Input/output connectors and expansion slots - (NF 8500R - Type 8681)


Input/output connectors and expansion slots

Input/output (I/O) connectors provide ports for transferring information into and out of the server.
You can connect a variety of I/O devices to the server, including a monitor, keyboard, mouse, and printer.
For more information on the ports and their specific technologies, see 'External options'.

At the rear of the server is an I/O function card that provides access to some I/O connectors.
Adapters installed in expansion slots might also provide I/O connectors.
The following illustration shows the expansion slots and the I/O connectors (ports) on the I/O function card, chassis, and the Advanced System Management PCI Adapter.

 

-1- External connector knockouts for Advanced System Management PCI Adapter token-ring option:
The chassis has an external connector knockout that can be used when you install the Advanced System Management PCI Adapter token-ring option.


-2- External SCSI device connector:
External SCSI devices attach here. The knockout for a second external SCSI connector is not used.


-3- Serial port A connector:
Serial signal cables for modems and other serial devices connect here to the 9-pin serial port A connector.
See 'Devices and I/O ports' for port assignment information.
If you are using a 25-pin signal cable, you need a 9-pin-to-25-pin adapter cable.


-4- Advanced System Management PCI Adapter 10/100 Mbps Ethernet port connector:
This connector attaches the Advanced System Management PCI Adapter to a network hub for remote communication.

Note: The Advanced System Management PCI Adapter 10/100 Mbps Ethernet connector cannot be accessed from the network operating system.
The connector is dedicated to connecting the Advanced System Management PCI Adapter to an Ethernet network through a service-processor interface, such as Netfinity Manager.


-5- Serial port B connector:
Serial signal cables for modems and other serial devices connect here to the 9-pin serial port B connector.
See 'Devices and I/O ports' for port assignment information.
If you are using a 25-pin signal cable, you need a 9-pin-to-25-pin adapter cable.


-6- Advanced System Management PCI Adapter dual serial port connector:
This connector can be used to attach to a Y-cable that is shipped with the server.
This Y-cable can be used to attach to a modem that is dedicated to communication with the Advanced System Management PCI Adapter.


-7- Advanced System Management Interconnect port connector:
This connector is used to attach other compatible service processors for remote access.


-8- Advanced System Management external power connector:
This connector is not used.


-9- Parallel port connector:
A signal cable for a parallel device, such as a printer connects here.


-1- Video port connector:
The monitor signal cable connects here.


-11- Universal Serial Bus connectors:
You can attach I/O devices to these two Universal Serial Bus (USB) connectors.
You need a 4-pin cable to connect devices to USB 1 or 2.
A hot-plug keyboard-and-mouse option can be cabled or uncabled from the USB connectors without error or loss of service.
Review the operating-system documentation to determine whether the operating system supports USB devices.

Note: If a standard (non-USB) keyboard is attached to the keyboard port, the USB ports are disabled while the power-on self-test (POST) is running, and no USB devices will work during POST.


-12- Power supply connectors:
The three system power cords connect here.


-13- PCI expansion slots:
The server has twelve 64-bit, PCI expansion slots. All PCI slots support hot-plug PCI adapters.


-14- Keyboard port connector:
The keyboard cable connects here.


-15- Mouse port connector:
The mouse cable connects here.
This port sometimes is called an auxiliary-device or pointing-device port.

Note: For pin assignments and other details about these connectors, see 'External options'.
