INTRODUCTION AND PLANNING _____________________________________ This chapter describes the features of the IBM 8225 Fast Ethernet Stackable Hub (8225) and provides information you will need to integrate 8225s into your new or existing network. THE 8225 ________ The 8225 is a stackable Fast Ethernet hub that comes in three models: o Model 001, which incorporates twelve 100BASE-TX Fast Ethernet ports supporting the IEEE 802.3u 100BASE-TX specification over category 5, 100-ohm UTP or ScTP cabling or 150-ohm STP-A cabling. Each 8225 can accommodate an optional Fast Expansion Module, providing connectivity to 10BASE-T/100BASE-TX, 100BASE-T4, or 100BASE-FX networks, offering maximum flexibility in system connectivity. o Model 002, which provides all of the connectivity features of Model 001 and includes an SNMP agent that permits management of one or more Model 001s. o Model 003, which incorporates all of the connectivity and management features of Model 002 plus a remote monitoring (RMON) agent. Figure 1-1. Front View of the IBM 8225 Fast Ethernet Stackable Hub FEATURES All models of the 8225 include these features: o Twelve 100BASE-TX ports with shielded RJ-45 connectors that support the IEEE 802.3u 100BASE-TX specification. All of the 100BASE-TX ports are Medium Dependent Interface-X (MDI-X) ports. These ports perform an internal crossover function that allows easy connection to other devices using standard cables. The twelfth port is also accessible without the internal crossover function, at the port marked "12-MDI," permitting connection to devices having an internal crossover function using standard straight-through cables. o Front panel slot to accommodate an optional, slide-in Fast Expansion Module for connecting to 10BASE-T/100BASE-TX, 100BASE-T4, or 100BASE-FX networks. o Three independent 100-Mbps Fast Ethernet backplanes. (C) Copyright IBM Corp. 1996 1-1 o Rear panel slot to accommodate an optional redundant power module. o EtherWatch LED bars to display hub utilization and collision rates. o Repeating of all Ethernet frame formats. o Auto-partitioning and reconnect of ports whose attached devices create excessive collisions. o Jabber protection by disabling a port that receives 64 KB of continuous transmission and re-enabling the port when the condition clears. o A serial management port for configuring the 8225., o LEDs that indicate link status, activity, and partition status at the port level. o Storage of vital configuration data in nonvolatile memory. o The 8225 can be configured to issue warnings or disable a port automatically when frames are received at that port from any MAC address other than the one authorized to send to that port. o Can be mounted in an EIA standard 19-inch rack (mounting brackets included). The 8225 can also be placed on a tabletop or shelf. o Up to 6 8225s in any combination of models can be configured in a stack. o Field upgrades; Model 001 can be upgraded to Model 002 or 003, and Model 002 can be upgraded to Model 003. Model 002 provides these additional features to the entire stack: o An SNMP agent that provides support for these Management Information Bases (MIBs): - RFC 1213 (MIB II) - RFC 1516 (Ethernet repeater MIB) - RFC 1643 (Ethernet MIB) - Novell Hub MIB - IBM private MIB (listed in Appendix B). o A serial management port for configuring the 8225, upgrading microcode out-of-band, and out-of-band management. o A user interface, accessible by means of VT100 terminal emulation (in-band) or Telnet (out-of-band), for issuing management commands and retrieving information and statistics concerning individual 8225s, backplanes, or the entire stack. o SNMP manageability over IP networks using the following frame formats: Ethernet Version 2 Ethernet SNAP. 1-2 8225 Hub Installation and Planning Guide o SNMP manageability over IPX(**) networks using the following frame formats: Ethernet Version 2 IEEE 802.3 (raw) IEEE 802.2 IEEE 802.2 SNAP. o Manageability using optional applications and platforms, such as IBM Nways Manager for Windows(**), Nways Campus Manager LAN for AIX(**), and Nways Campus LAN for HP/UX(**). o For IP networks: - SNMP manageability over a Serial Line Internet Protocol (SLIP) link to the Management port - Support for the Bootstrap Protocol (BootP) for configuring and upgrading the microcode of any 8225 Model 002 or Model 003 - Support for TFTP for upgrading the microcode of any Model 002 or Model 003 - Telnet support. o For IPX networks, Novell Hub Management Interface (HMI) compliance. Model 003 provides these additional features: o All connectivity features, plus all management features of Model 002. In addition, Model 003 incorporates an RMON agent providing the functions defined in RFC-1757. STACKS A stack is formed when up to six 8225s are connected together. To create a _____ stack, two or more 8225s must be interconnected using optional, 8-inch, hub interconnect cables. For more information on interconnecting 8225s, see "Interconnecting 8225s" on page 1-4 and "Connecting Hub Interconnect Cables" on page 2-5. A managed stack is made up of any combination of Model 001s, Model 002s, and _______ Model 003s, as long as at least one Model 002 or 003 is included in the stack. In stacks with only one Model 002 or Model 003, that unit will automatically be designated the primary management agent, regardless of its physical position in the stack. For stacks having more than one Model 002 or Model 003, the following rules are observed: o The unit that is physically nearest the top of the stack will automatically be designated the primary management agent and the remainder will be designated backup management agents in order of their physical position in the stack. Chapter 1. Introduction and Planning 1-3 o Whenever a Model 003 is present, it will be designated the management unit, even if its physical position in the stack is lower than a Model 002 in the same stack. o In a stack with more than one management unit, in case of the failure of the primary management agent, the management agent that is physically next lowest in position in the stack will automatically assume primary management agent responsibility. For more information on managed stacks, see "Understanding Managed Stacks" on page 1-4. An unmanaged stack is made up exclusively of Model 001s. _________ There are four ways to manage the 8225: Using a local VT100 terminal emulator out-of-band Using SNMP over SLIP out-of-band Using Telnet over an IP network connection in-band Using SNMP over an IP or IPX network connection in-band. INTERCONNECTING 8225S You can increase the number of ports available to end stations by adding 8225s to a network, interconnecting them using the Fast Expansion Module or the hub interconnection cable. When the hub interconnection cable is used, management information can be passed between hubs, enabling management of an entire stack. Cabling and connector requirements for the Fast Expansion Modules are given in "Cabling Requirements for the Fast Expansion Modules" on page 1-9. UNDERSTANDING MANAGED STACKS ____________________________ This section describes how 8225s in a stack communicate with one another, the effects of segmenting 8225s within a stack, and how to link segmented 8225s. INTER-8225 COMMUNICATIONS IN MANAGED STACKS In an 8225 stack there are three 100-Mbps backplanes and one management backplane (or bus). This management backplane is used by the management agents in Model 002 and Model 003 to retrieve management information from all units in the stack. Regardless of the segmentation status of any 8225 or its position in the backplane, the hub retains its full management capability and the ability to access a wide range of information concerning all 8225s in a stack. Using any of the management methods mentioned above, you can perform any of the following actions on any 8225 in a stack while attached to the Model 002 1-4 8225 Hub Installation and Planning Guide or Model 003 that is currently the primary management hub as indicated by the Prim LED: o Restart the system o Display system information o Issue management commands to any hub in the stack - SNMP configuration - Port intrusion control - Segment configuration - Hub configuration - TFTP or XMODEM upgrades of microcode - Port configuration - User passwords - Backup ports - Console lockout o Collect statistics at the port, hub, or segment level. In addition, the management functions as defined in RFC-1757 can be performed from a Model 003. The RMON agent in the Model 003 implements the SNMP protocol, so it can be managed by any SNMP-based network management system. WHY SEGMENT 8225S WITHIN A STACK? Three major uses of segmentation are to improve performance, to troubleshoot, and to isolate groups of users. This section details those uses. "Segmenting 8225s within a Stack" on page 1-6 explains how segmenting is controlled. Improving Performance In an unsegmented stack, all of the 8225s remain in the factory-default segmentation status and are assigned to Backplane 1. This configuration represents a single collision domain. All devices attached anywhere in such a stack see all of the Ethernet frames generated anywhere in the stack, thus they share a single 100-Mbps bandwidth. As network traffic increases, excessive collisions can cause network performance to slow. You can improve performance by segmenting one or more 8225s in the stack to another backplane or by isolating them completely from any backplane. Each backplane or isolated 8225 is a separate collision domain, thus providing multiple 100-Mbps bandwidths. To enable segmented 8225s to communicate with the rest of the stack, interconnect them using the Fast Expansion Module or a bridge, router or switch. See "Linking Segmented 8225s" on page 1-6 for more detail. Chapter 1. Introduction and Planning 1-5 Troubleshooting Segmentation can help you isolate areas of your network that are experiencing problems. You can segment 8225s one at a time while monitoring stack performance. This technique can help you localize a problem area to the devices attached to a specific 8225. Isolating User Groups You might have users in your network who have no need for connectivity outside their department or workgroup. By placing their workstations on a separate backplane, you can limit their network access and isolate their bandwidth demands from the remainder of the network while retaining management of the 8225s. SEGMENTING 8225S WITHIN A STACK You can use a VT100 terminal emulator or an SNMP management application to connect an 8225 to any of the three backplanes or to isolate it completely from the stack. When this is done, the 8225 is said to have been segmented. _________ Even though one or more hubs have been logically removed from the Fast Ethernet bus, the management bus permits the management information described in "Inter-8225 Communications in Managed Stacks" on page 1-4 to be passed. LINKING SEGMENTED 8225S When you segment an 8225, you cause it either to be connected to another backplane or to be isolated completely from the rest of the stack. Devices connected to 8225s in any backplane are able to communicate with all other devices connected to any 8225 in that backplane. Each backplane is a separate collision domain, as are any 8225s that have been isolated. One easily implemented method of interconnecting multiple backplanes is by means of the 10BASE-T/100BASE-TX Fast Expansion Module. You can connect a 10BASE-T/100BASE-TX Fast Expansion Module in one 8225 to a port in an 8225 that is in a different backplane. You can also interconnect 8225s in different backplanes using a bridge, router, or Fast Ethernet switch. In order to manage a stack of 8225s: o The 8225 you want to manage must be a Model 002 or Model 003, or it must be connected in a stack that includes at least one Model 002 or Model 003, and ___ o There must be a Fast Ethernet link between the 8225 to which your management workstation is attached and the Model 002 or Model 003 that is serving as the primary management unit for the stack. 1-6 8225 Hub Installation and Planning Guide ASSIGNING BACKUP PORTS ______________________ A managed stack provides the option of making redundant connections to network-critical devices, such as servers or LAN switches. You can use the VT100 interface or any SNMP-based network management application to assign backup ports. Any port in an 8225, including those on Fast Expansion Modules, can be used as a backup for any other port. A stack can have up to 18 pairs of redundant links. The primary and backup ports can be on separate backplanes. Note that you must establish two physical connections to the desired device. When a backup port has been configured and activated, the primary port will be enabled and the backup port will be disabled to prevent looping. Before a backup port is in operation, the Link/Activity LED will indicate activity on the PRIMARY port and the Partition LED for the BACKUP port will be on. When the primary port is disabled, the secondary port will be enabled to keep the device connected. When you reset the backup function, the secondary port will be disabled and the primary port will be re-enabled. When a backup port is in operation, the Link/Activity LED will indicate activity on the BACKUP port and the Partition LED for the PRIMARY port will be on. Chapter 1. Introduction and Planning 1-7 FAST ETHERNET PLANNING ______________________ The size of each Ethernet collision domain you create is limited by these factors: o The cable length restrictions unique to each type of segment (that is, for 100BASE-TX, 100BASE-T4, and so on) o If you will use optical fiber links: - The limit of 2000 m (6561 ft) for full-duplex connection of any two devices in one collision domain - The limit of 412 m (1352 ft) for half-duplex connection of any two devices in one collision domain These factors are explained in greater detail in the following sections. MAXIMUM SEGMENT LENGTHS A Fast Ethernet segment is the total length of cable between either two repeaters or between a repeater and an attached device. The different types of Fast Ethernet supported by the 8225 place different limitations on segment lengths. +---------------------------------------------------------------------------+ | Table 1-1. Maximum Segment Lengths for the Supported Fast Ethernet Types | +------------------------+--------------------------------------------------+ | FAST ETHERNET TYPE | MAXIMUM SEGMENT LENGTH | +------------------------+--------------------------------------------------+ | 100BASE-TX | 100 m (328 ft) | | or | | | 10BASE-T | | +------------------------+--------------------------------------------------+ | 100BASE-T4 | 100 m (328 ft) | +------------------------+--------------------------------------------------+ | 100BASE-FX | 412 m (1352 ft) | | | Half duplex | | | | | | 2000 m (6561 ft) | | | Full duplex | +------------------------+--------------------------------------------------+ CABLES AND CONNECTORS _____________________ Cable and connector requirements differ depending on the port to which each cable connects. UTP and STP cable pinouts can be found in Appendix A, "Cable Pinout Diagrams" on page A-1. 1-8 8225 Hub Installation and Planning Guide CABLING REQUIREMENTS FOR 100BASE-TX PORTS This section describes the cables required to connect the 8225's 100BASE-TX ports to network devices such as workstations and servers. Problems with LANs are frequently due to incorrect cable selection or poor cabling practices. You should select components carefully and inspect installations for good installation practices so that your 100BASE-TX network will operate as intended. Your 100BASE-TX network will operate correctly on category 5, 100-ohm UTP or ScTP cable and connecting hardware as specified in the ANSI/TIA/EIA 568-A or CSA T529 standards. Your 100BASE-TX network will also operate on 150-ohm STP-A cable and components as specified in these standards. In addition, your network will operate on IBM Cabling System types 1, 6, and 9, 150-ohm STP or STP-A cable. If you are using 150-ohm cabling systems, impedance-matching devices must be used in conjunction with the cable. Your 100BASE-TX network will also operate correctly on category 5, 100- and 120-ohm, balanced, shielded or unshielded cables and components as specified in the ISO/IEC 11801 standard. It will also operate on 150-ohm, balanced, shielded cables and components as specified in the ISO/IEC standard. In addition, your network will operate on any link that meets the specifications of a Class D link as specified in the standard; this includes IBM Cabling System type 9 STP cabling. If you are using 120- or 150-ohm cabling systems, impedance-matching devices must be used in conjunction with the cable. All devices connected to the cables must be grounded. Do not use telephone extension cables in 100BASE-TX networks. The wire pairs in those cables are not twisted and the cable does not meet other requirements for use in a 100BASE-TX network. Applicable Cabling Standards In the United States, the ANSI/TIA/EIA 568-A Commercial Building ______________________________________ Telecommunications Standard has been widely adopted. The Canadian Standards ___________________________ Association has also participated in the development of this standard and issues a parallel document known as T529; the most current version of this ____ document is dated 1995. Many other countries use ISO/IEC 11801 Information _________________________ technology - Generic cabling for customer premises. __________________________________________________ It is good practice to use only those components that have been certified by an independent testing laboratory as meeting one or more of the standards. In the case of IBM Cabling System types 1, 6, and 9 cable, certification should be either to the IBM specification or to the applicable standard. CABLING REQUIREMENTS FOR THE FAST EXPANSION MODULES Cable and connector requirements differ depending on the Fast Expansion Module you use. Chapter 1. Introduction and Planning 1-9 10BASE-T/100BASE-TX Fast Expansion Module This Fast Expansion Module incorporates two RJ-45 connectors. For connection to 100BASE-TX networks, you should use cables meeting the requirements outlined in "Cabling Requirements for 100BASE-TX Ports." For connection to 10BASE-T networks, you can use category 3 or category 4 cables in addition to those specified for use in 100BASE-TX networks. 100BASE-T4 Fast Expansion Module This Fast Expansion Module incorporates two RJ-45 connectors. You can use category 3, 4, or 5 100-ohm UTP or ScTP cables. 100BASE-FX Fast Expansion Module This Fast Expansion Module incorporates two ST connectors. Use 62.5/125-micron multimode optical fiber that meets the specifications in TIA/EIA 568A or ISO/IEC 11801. The maximum length of optical fiber cable between devices should not exceed 2000 meters (6561 ft) if the link is being operated in full-duplex mode. CABLING REQUIREMENTS FOR THE MANAGEMENT PORT The Management port is a standard DB-9 male connector that provides an EIA/TIA 232-E (was RS 232-C) serial interface. You can connect locally, with a null-modem cable, or remotely, over telephone lines, using serial cables and modems at each end. Once connected, you can manage the 8225 and upgrade microcode. This is sometimes called out-of-band management. ___________ You can make a null-modem cable by connecting a null-modem adapter to a standard serial cable. PROTECTED VITAL CONFIGURATION DATA __________________________________ The following configuration information is stored in nonvolatile memory and will survive a power outage: o System name and location o Segment to which the hub is connected o ID number assigned to the hub o Password assigned to the hub The above are retained for all models.

If you plan to use an optional redundant power module, you will need two power cords and two connections. In order to ensure maximum redundancy, the connections should be made to outlets on separate ac circuits. NOTE: For safety reasons, it is recommended that the connection be made first to the 8225, then to the ac outlet.. The 8225's internal, auto-ranging power module adapts to voltages between 100 and 240 V ac at frequencies of 50 to 60 Hz, 3 Hz. Following are characteristics of the 8225's power module: POWER USAGE (MAXIMUM) 73 watts @ 249 BTU per hour (Model 001) 102 watts @ 348 BTU per hour (Model 002) 106 watts @ 362 BTU per hour (Model 003) 17 watts @ 58 BTU per hour (Expansion module) LINE CURRENT (MAXIMUM) 1.6 A @ 120 V ac; 0.8 A @ 240 V ac KVA (WORST CASE) 0.16 kVA PHYSICAL CHARACTERISTICS ________________________ This section gives the dimensions and weight of an 8225.

SPACE REQUIREMENTS If you will connect multiple 8225s in a stack, be sure that you have enough space available in your rack or shelf for the number of hubs that will be stacked together. Keep in mind that the length of a hub interconnection cable is fixed at 203 mm (8 in.). Allow at least 51 mm (2 in.) at the sides of the 8225 for air circulation and cable connections. A minimum of 305 mm (12 in.) of clearance at the rear of the 8225 is required in order to insert and remove the power modules. Leave eight inches in front for viewing the LEDs, installing Fast Expansion Modules, connecting cables, and for air circulation.

Introduction and Planning 1-15 DOCUMENTING YOUR INSTALLATION _____________________________ It is always a good idea to maintain charts or other documentation that pinpoint key aspects of your installation. By doing this, you will make your tasks in such areas as system expansion, reconfiguration, or troubleshooting easier to perform. RACK DOCUMENT You should document all components installed in each rack in your establishment. The larger the organization, the more useful this can be. Create a rack inventory document for each of the racks where you will be installing components. Indicate the location of each component in this document. Include the unit ID and model number of each component. STACK DOCUMENT You should document each 8225 stack. Retain this document as a record of which IP address has been assigned to each stack or individual 8225, each 8225's unit ID, and the location of each 8225. SETUP AND CABLING DOCUMENT A setup and cabling diagram can be used to indicate to the installer how and where to mount the 8225 and how to connect the appropriate cables to it. Include enough building and location information to enable the installer to find where to install the 8225. Include the 8225's backplane location, unit ID, and IP or IPX address. Indicate whether a Fast Expansion Module should be installed and, if so, the type (that is, 10BASE-T/100BASE-TX, 100BASE-T4, or 100BASE-FX). For each port, record an identifier for the device at the other end of the cable. Include information such as the device's MAC address and physical location. Record the identifier for the port to which the installer should connect the cable from the 8225's port. If the 8225 is to be installed in a wiring closet, indicate that the installer should connect a patch cable from a port in the 8225 to a port in a patch panel. LOCATOR DOCUMENT You should maintain information that enables you to relate adapter addresses to their physical location and device. This information is useful for problem determination and should be kept current, especially in larger installations. Each device that attaches to an 8225 is known to the network by its adapter address. This address can be one of two types: universally administered or 1-16 8225 Hub Installation and Planning Guide locally administered. See the adapter's documentation to learn how to determine the address of a particular adapter. Record adapter and hub addresses of all devices in the network in numerical order. Record the physical locations of all devices by building and room number. In addition to recording the device identification, you should also indicate such functions as hubs, bridges, print servers, file servers, gateways, and switches. Chapter 1.

INSTALLING AND ROUTING CABLES _____________________________ Remember these tips when connecting cables: o Avoid stretching or bending the cables. o Avoid routing the cables near potential sources of electromagnetic interference, such as motorized devices or fluorescent lights. o Route cables away from aisles and walkways to avoid creating trip hazards. Use floor cable covers to secure cables if such routes cannot be avoided. CONNECTING CABLES TO 100BASE-TX PORTS AND FAST EXPANSION MODULES 1. Refer to your network documentation to determine each cable's port or Fast Expansion Module assignment. 2. Using appropriate connectors, connect the cables to the ports or Fast Expansion Modules. 3. Label the cables so that it will be easy to identify the device at the other end of the cable if you have to troubleshoot a network problem. At the end of the cable nearest the 8225, place a label containing a unique identifier for the cable, the location and MAC address of the 2-4 8225 Hub Installation and Planning Guide device at the other end of the cable, and the number of the port to which the device is attached. 4. If required, at the attached device's end of each cable, connect a cable from the device to any faceplate or other intermediate connection point, as appropriate. 5. Label the cables so that it will be easy to identify the 8225 port at the other end of the cable if you have to troubleshoot a network problem. At the end of the cable nearest the attached device, place a label containing a unique identifier for the cable, the location and MAC address of the 8225 at the other end of the cable, and the number of the 8225 port to which the device is connected. CONNECTING HUB INTERCONNECT CABLES If you will be configuring multiple 8225s into one or more stacks, you will need optional hub interconnect cables (P/N 85H3825). One cable is required for every two hubs that will be interconnected. This cable is illustrated in Figure 2-4. Figure 2-4. 8225 Hub Interconnect Cable (P/N 85H3825) If you will be connecting multiple 8225s using the hub interconnect cable, follow the steps below. If not, go to "Powering On the 8225" on page 2-6. 1. Connect one end of the cable to the Down port of the 8225 that is ____ physically nearest the top of the stack. Be sure that the cable is firmly seated and that the latches are engaged. 2. Connect the other end of this cable to the Up port of the 8225 that is __ physically next lowest in the stack. Be sure that the cable is firmly seated and that the latches are engaged. 3. Repeat the above steps for each hub in the stack, progressing downward. NOTE: Never allow a hub interconnect cable to remain partially attached. If a hub interconnect cable is disconnected from one 8225 but is left connected to the other 8225, Ethernet traffic to all backplane buses will be disrupted. In Figure 2-5, the topmost 8225 is Model 002 and the two lower units are Model 001s. Note the hub interconnect cable connections. In this example, the Model 002 would be identified as occupying position 1, the Model 001 in the middle would occupy position 2, and the Model 001 on the bottom would occupy position 3. Figure 2-5. Example 8225 Stack Chapter 2. Installing the 8225 2-5 CONNECTING A MODEM OR A NULL-MODEM CABLE TO THE MANAGEMENT PORT If you have a modem or a null-modem cable to install, follow the steps given here. If not, go to "Powering On the 8225." 1. If you are installing a modem, unpack it and install it according to the manufacturer's instructions. An installed modem should be set to force Data Set Ready (DSR) signals. Typically, this is done by setting a switch on the modem. Refer to the documentation that came with your modem for specific instructions. 2. Connect one end of the serial cable (modem connection) or one end of the null-modem cable (direct connection) to the 8225 port labeled Management. __________ Figure 2-6. Location of the Management Port o If you have a managed stack, this will be the Model 002 or Model 003 whose Prim LED is on, indicating that it is the primary management ____ agent. o If you have an unmanaged stack of Model 001s, this will be any of the units. 3. If you are installing a modem, connect the other end of the cable to the modem and connect the modem to the telephone system. If you are installing a null-modem cable, connect the other end of the cable to the communications port on your computer. 4. Continue with "Powering On the 8225." POWERING ON THE 8225 ____________________ This section describes how you should expect the LEDs to function when you power the 8225 ON. 1. Connect the power cord to the connector at the back of the 8225, as shown in Figure 2-7. NOTE: If you have installed an optional, redundant power module, you will connect two power cords. Figure 2-7. Connecting the Power Cord 2. Insert the other end of the power cord or cords into the electric outlet. NOTE: There is no power switch on the 8225 3. Look for the following LED blink sequence: 2-6 8225 Hub Installation and Planning Guide o First, all LEDs on the front panel should come on for approximately one second. o Then, the Link/Activity LEDs on the individual ports should blink on, then off, in sequence from left to right (port 1 to port 12). NOTE: Because the POST diagnostics are of a brief duration, it may appear that one or more of the LEDs did not blink on and off. The important thing to note is whether any LEDs remain on and the Partition LEDs blink for 1 to 2 seconds. If this occurs, refer to _________ Chapter 4, "Troubleshooting and Service." o Finally, all LEDs that are appropriate for the particular 8225 stack configuration you have installed (such as the power module, Fast Expansion Module, management, and backplane LEDs) should reach their normal states. Refer to Table 3-1 on page 3-48 and Table 3-2 on page 3-50 for more information concerning the LEDs. Chapter 2. Installing the 8225 2-7 2-8 8225 Hub Installation and Planning Guide CHAPTER 3. 8225 ADMINISTRATION _______________________________ This chapter explains how to manage your 8225 installation.. Its primary emphasis will be on using the built-in user interface. You can also use SNMP to manage your 8225 installation. See "Preparing for SNMP Management" on page 3-54 for details. THE 8225 USER INTERFACE PROGRAM _______________________________ The 8225 incorporates a powerful user interface that can be used to manage individual 8225s or a complete stack using a terminal emulation program that supports VT100 emulation (out-of-band), or using Telnet over an IP connection (in-band). NOTE: Telnet is a component of most TCP/IP applications. You will need to install TCP/IP before you can take advantage of this option. For more information on using Telnet over an IP connection, see"Management Using Telnet" on page 3-53 . MANAGEMENT USING TERMINAL EMULATION SOFTWARE You can manage your 8225 installation in one of two ways using terminal emulation software: o By means of a direct, null-modem cable connection o By means of the public telephone network, using modems Obtain and install a terminal emulation software application that is compatible with your workstation's operating system and that supports VT100 emulation. Communicating Using a Null-Modem Cable Configure the terminal emulation application as follows: o Speed of 9600 bps o No parity o 8 data bits o 1 stop bit o VT100 emulation o The communications port of the workstation that you have configured in the emulation software NOTE: Some emulation applications (such as many Windows-based programs) use the workstation keyboard's cursor movement keys; for example, to switch between windows. Because the 8225's user interface program uses the cursor (C) Copyright IBM Corp. 1996 3-1 movement keys, it is necessary when using such terminal emulators to turn off this feature. In Windows 3.1, for example, perform the following steps: 1. From the Program Manager window, double-click the Accessories group icon. 2. Inside the Accessories window, double-click the Terminal icon. This will open a blank terminal emulation session. 3. From within the Terminal window, click SETTINGS from the menu bar. 4. Select TERMINAL PREFERENCES. 5. Deselect the check box "Use Function, Arrow, and Control Keys for Windows." 6. Select OK. 7. You can save your current session settings by selecting FILE from the menu bar and selecting SAVE AS.... Give a file name and open this file the next time you start your emulation session. For information on connecting an 8225 to a null-modem cable, see "Connecting a Modem or a Null-Modem Cable to the Management Port" on page 2-6. SPECIAL CONSIDERATIONS: Because most communications software assumes that you will be using a modem, if you will be connecting using a null-modem cable, you need to be certain that your emulation software supports communication with a device that is directly attached to your workstation. Follow any special instructions from the application manufacturer concerning configuration steps that may be required to support communication with a directly attached device. Communicating Using a Modem If you will be communicating with the 8225 by means of a modem connection, you will need to install a second modem and connect it to your computer. Configure the terminal emulation application as follows: o Maximum speed of your modem o No parity o 8 data bits o 1 stop bit o VT100 emulation o The workstation's communications port that will be used 3-2 8225 Hub Installation and Planning Guide ESTABLISHING A SESSION WITH THE 8225 To initiate a session using the 8225's user interface program, perform the following steps: 1. Either o Invoke your emulation software to establish a direct connection by means of the null-modem cable; or o Invoke your emulation software and dial the number of the modem that is attached to the 8225. 2. After you have established a connection with the 8225, you will be presented with one of two situations: o If the 8225 was already powered on, you will see a blank screen. o If you power on the 8225 after establishing the connection, you will see a series of diagnostic messages. NOTE: If any of these messages indicates a failure, see Chapter 4, "Troubleshooting and Service." 3. In either case, press ENTER two or three times. You will be prompted for a password (Model 001) or user and password (Model 002 and Model 003). o All 8225 Model 001s are shipped with a password of ADMIN. Persons accessing the Model 001 using this password will have both read and write capability and will be able to alter the configuration of the 8225, o All Model 002s and Model 003s are shipped with a user name of ADMIN and no preset password. A password can be assigned (see "User Passwords" on page 3-35). Persons accessing the 8225 using this combination will have both read and write capability and will be able to alter the configuration of the 8225 installation, as well as collect hub, segment, and stack statistics. o In addition, all 8225 Model 002s and Model 003s are shipped with a user name of GUEST. Persons accessing the 8225 using this user name will have read capability only and will be able to read, but not change, the installation's configuration and collect statistics. If you are connecting to a Model 002 or Model 003, you must press ENTER after entering the user name and before entering the password. Press ENTER a second time after entering the password. 4. You are now presented with the 8225's main menu. The remainder of this chapter will treat each of the management options available to you from these menus. Chapter 3. 8225 Administration 3-3 MODEL 001 MANAGEMENT OPTIONS ____________________________ NOTE: If you attempt to communicate with a Model 001 that is configured in a managed stack, a message will be displayed informing you that a management agent has been detected and that the Management Port of the Model 001 has been disabled.

The latest IBM 8225 private MIB is also available from these sites under the file name 8225MIB.EXE. ___________ To get the microcode from the BBS: 1. Prepare your computer to call the IBM PC Company BBS. You need a computer with a modem and communications software in order to make the call. The BBS auto-senses the speed of your modem, supporting speeds between 1200 and 14 400 bps. Make sure that your communications software is set to use 8 data bits, no parity, 1 stop bit, and no flow control. 2. Dial (919) 517-0001. If you are a first-time user, you will be prompted for your first and last names, and then you will be asked to enter a password. You might want to write your password in the following space. +--- YOUR PASSWORD -----------------------------------------------------+ | | | IBM Personal Computer Company BBS password: _________________ | | | +-----------------------------------------------------------------------+ 3. Find the file containing the microcode and download it to your computer. Using the BBS' search facility, search for 8225. The name of the ____ microcode file will be in the format 8225xddd.EXE, where: ____________ x is a letter indicating the target product type: S for SNMP, or _ _ Model 002, and R for RMON, or Model 003. _ ddd is a 3-digit number that indicates the microcode version. ___ Return to the main menu, and then use your communications program to transfer the microcode file to your computer. If your communications software offers the option, download the file in binary form. ______ NOTE: For convenience and to avoid overwriting existing files, you might want to place the file into a temporary subdirectory that you create for the purpose. 4. Decompress the microcode file. At a DOS or OS/2 command prompt, enter 8225XDDD, where x is the target _ product and ddd is the appropriate version number, and the compressed ___ file will decompress into two files: Chapter 3. 8225 Administration 3-51 o The microcode file, IBMxddd.IMG ___________ o A README file, README.TXT __________ 3-52 8225 Hub Installation and Planning Guide To get the files from the Internet: 1. Access the IBM PC Company anonymous ftp site: o If you are using a Web browser, the URL is: ftp://ftp.pc.ibm.com o If you are using a command-line invocation of FTP, the address is: ftp.pc.ibm.com 2. The files are in the pub/pccbbs/network subdirectory. __________________ 3. If the software you are using provides the option, download the files in binary form. ______ NOTE: For convenience and to avoid overwriting existing files, you might want to place the file in a temporary subdirectory that you create for the purpose. 4. Decompress the files as outlined in step 4 under "Getting New Microcode" on page 3-51. MANAGEMENT USING TELNET _______________________ You can access your 8225 using Telnet, either in-band, over an Ethernet connection or out-of-band, using SLIP. When you connect using Telnet, you will see the user interface that has already been documented in this chapter. CONFIGURING FOR SLIP The 8225 management unit supports two IP addresses, one for Ethernet and one for the serial line. When configuring your 8225, these addresses are entered on the Segment Configuration panel (see Figure 3-10 on page 3-15) in the IP Address and Serial IP fields, respectively. Both of these addresses share a common subnet mask. In order for SLIP to function, both IP addresses must be on the same network. If the subnet mask is "255.255.255.0", you might configure the two addresses "9.123.1.9" (Ethernet IP address) and "9.123.1.10" (serial line IP address). If the addresses are on the same network, the first three portions of the IP address must be identical. Another requirement is that the SLIP client/host (the PC or device that is connected to the 8225 by a serial link) must use the same IP address and subnet mask as the 8225 Serial Line IP. Using the above example, the address and subnet mask for the SLIP client/host must be "9.123.1.10" and "255.255.255.0", respectively. Chapter 3. 8225 Administration 3-53 PREPARING FOR SNMP MANAGEMENT _____________________________ SNMP management requires that you have a managed stack: that is, that your stack contain at least one 8225 Model 002 or Model 003. Model 002 incorporates an SNMP agent and Model 003 incorporates an RMON agent that implements the SNMP protocol. Model 002 supports the following MIBs: o MIB II (RFC1213) o Repeater MIB (RFC1516) o Ethernet MIB (RFC1623) o Novell Hub MIB o IBM 8225 Private MIB Model 003 supports all of the above, as well as the RMON MIB. These MIBS can be managed by most network management applications, including IBM Nways Manager for Windows, Nways Campus Manager LAN for AIX, and Nways Campus LAN for HP/UX. The 8225 supports SNMP/IPX and Novell HMI specifications, enabling this system to be integrated seamlessly into the NetWare environment. Before you can use an SNMP-based network management application, you must configure your primary 8225 management agent using either the user interface program or BootP. For information on the user interface program, see "The 8225 User Interface Program" on page 3-1. SETTING AN IP ADDRESS USING BOOTP If you have selected one of the BootP options on the Hub Configuration panel (Figure 3-12 on page 3-18), the 8225 automatically sends out BootP requests every 6 seconds for up to 2 minutes after a power-up. The BootP request contains the MAC address of the 8225. The requests seek a BootP server, which you must have previously configured with an address resolution table containing MAC addresses and corresponding ________________________ IP addresses. When the BootP server receives the request, it sends an IP address to the requesting 8225's MAC address. NOTE: BootP requests will not pass through routers. BootP servers vary from manufacturer to manufacturer, so use the following example for reference only. Refer to your BootP server's documentation for specific instructions. 3-54 8225 Hub Installation and Planning Guide +----------------------------------------------------------------------------------+ | | | | | ibvdddmmmmmmmmmmmm:\ | | HT=ethernet:\ | | HA=mmmmmmmmmmmm:\ | | IP=ddd.ddd.ddd.ddd:\ | | SM=ddd.ddd.ddd.ddd:\ | | GW=ddd.ddd.ddd.ddd | | | | | Figure 3-31.

You must remove the cover of the 8225 to observe these LEDs. The POWER LED should be ON, the FAIL LED should be OFF, and the WATCHDOG LED should blink during repeater activity. If your 8225 is not working correctly and any of these is failing, replace the management board. Chapter 4. Troubleshooting and Service 4-3 HOT-SWAPPING 8225S You can disconnect the hub interconnect cable from an 8225 and plug it into a replacement 8225 without powering off the other 8225s in the stack (that is, you can hot-swap 8225s). If you hot-swap an 8225, the ports will take 1 or 2 minutes to resynchronize; however, each 8225 performs repeater functions normally while resynchronizing. All Ethernet traffic will be disrupted during the time that interhub cabling is not fully connected. To hot-swap an 8225: 1. Disconnect the power cord from the ac outlet and then from the 8225 that is to be replaced. 2. Unplug all the cables connected to the hub that is being replaced, making sure to label the cables so that you will know where to reconnect them. 3. If the 8225 you are removing from the stack has a Fast Expansion Module, and the replacement does not, remove the Fast Expansion Module from its slot and install it in the replacement 8225. NOTE: Make sure that the power to an 8225 is disconnected before you remove or install its Fast Expansion Module. 4. Connect the cables to the ports in the replacement 8225. 5. Connect the power cord to the 8225 and then connect the other end to the ac outlet. PROBLEM DETERMINATION THROUGH THE MANAGEMENT PORT When power is applied to an 8225 hub, a set of self-tests is performed. To review the results of these tests, you can connect a computer that has a terminal emulation program to the Management port, remove power from the 8225 to be tested, and then reconnect power. The result of the self-test is displayed on the terminal. For details about terminal emulation programs see Chapter 3, "8225 Administration" on page 3-1. 4-4 8225 Hub Installation and Planning Guide SAMPLE 1 +----------------------------------------------------------------------------------+ | | | | | | | IBM 8225 Fast Ethernet Stackable Hub Model 001 | | Power-up System Self-Diagnostic Process | | vn.nn mm-dd-yy (C)Copyright IBM corp. | | | | | | SYSTEM TESTS : | | ---------------------------------- | | Boot EPROM checksum test ...

The term "Machine" means an IBM machine, its ________________________________________________________________________ features, conversions, upgrades, elements, or accessories, or any combination _____________________________________________________________________________ of them. Unless IBM specifies otherwise, the following warranties apply only _____________________________________________________________________________ in the country where you acquire the Machine. If you have any questions, _________________________________________________________________________ contact IBM or your reseller. _____________________________ +---------------------------------------------------------------------------+ | | | MACHINE: IBM 8225 Fast Ethernet Stackable Hub | | | | WARRANTY PERIOD*: 1 year | | | | *Contact your place of purchase for warranty service information. | _________________________________________________________________ | | +---------------------------------------------------------------------------+ PRODUCTION STATUS Each Machine is manufactured from new parts, or new and used parts. In some cases, the Machine may not be new and may have been previously installed. Regardless of the Machine's production status, IBM's warranty terms apply. THE IBM WARRANTY FOR MACHINES IBM warrants that each Machine 1) is free from defects in materials and workmanship and 2) conforms to IBM's Official Published Specifications. The warranty period for a Machine is a specified, fixed period commencing on its Date of Installation. The date on your receipt is the Date of Installation, unless IBM or your reseller informs you otherwise. During the warranty period IBM or your reseller, if authorized by IBM, will provide warranty service under the type of service designated for the Machine and will manage and install engineering changes that apply to the Machine. For IBM or your reseller to provide warranty service for a feature, conversion, or upgrade, IBM or your reseller may require that the Machine on which it is installed be 1) for certain Machines, the designated, serial-numbered Machine and 2) at an engineering-change level compatible with the feature, conversion, or upgrade. Many of these transactions involve the removal of parts and their return to IBM. You represent that all removed parts are genuine and unaltered. A part that replaces a removed part will assume the warranty service status of the replaced part. (C) Copyright IBM Corp. 1996 C-1 If a Machine does not function as warranted during the warranty period, IBM or your reseller will repair it or replace it with one that is at least functionally equivalent, without charge. The replacement may not be new, but will be in good working order. If IBM or your reseller is unable to repair or replace the Machine, you may return it to your place of purchase and your money will be refunded. If you transfer a Machine to another user, warranty service is available to that user for the remainder of the warranty period. You should give your proof of purchase and this Statement to that user. However, for Machines which have a life-time warranty, this warranty is not transferable. WARRANTY SERVICE To obtain warranty service for the Machine, you should contact your reseller or call IBM. In the United States, call IBM at 1-800-IBM-SERV (426-7378). In Canada, call IBM at 1-800-565-3344. You may be required to present proof of purchase. IBM or your reseller will provide certain types of repair and exchange service, either at your location or at IBM's or your reseller's service center, to restore a Machine to good working order. When a type of service involves the exchange of a Machine or part, the item IBM or your reseller replaces becomes its property and the replacement becomes yours. You represent that all removed items are genuine and unaltered. The replacement may not be new, but will be in good working order and at least functionally equivalent to the item replaced. The replacement assumes the warranty service status of the replaced item. Before IBM or your reseller exchanges a Machine or part, you agree to remove all features, parts, options, alterations, and attachments not under warranty service. You also agree to ensure that the Machine is free of any legal obligations or restrictions that prevent its exchange. You agree to: 1. obtain authorization from the owner to have IBM or your reseller service a Machine that you do not own; and 2. where applicable, before service is provided -- a. follow the problem determination, problem analysis, and service request procedures that IBM or your reseller provide, b. secure all programs, data, and funds contained in a Machine, and c. inform IBM or your reseller of changes in a Machine's location. IBM is responsible for loss of, or damage to, your Machine while it is 1) in IBM's possession or 2) in transit in those cases where IBM is responsible for the transportation charges. EXTENT OF WARRANTY IBM does not warrant uninterrupted or error-free operation of a Machine. The warranties may be voided by misuse, accident, modification, unsuitable physical or operating environment, improper maintenance by you, removal or alteration of Machine or parts identification labels, or failure caused by a product for which IBM is not responsible.
