Features

The IBM Quad-B2 (10Base-2) PeerMaster MicroChannel adapter provides the ability to connect a PS/2 MicroChannel server to four separate 10Mbps Ethernet LAN segments:

• Performs high performance data transfers between the host PC and adapter.
• Provides high performance data transfers among ports on an adapter.
• Provides high performance data transfers among ports across multiple adapters with no host processor intervention.
• Provides a cost efficient, high performance means to forward cross-segment traffic without impacting server performance.
• Performs 64-bit data transfer across the Micro Channel at burst rates of 640Mbps, which equals the total bandwidth of 64 Ethernet ports.

Supported Systems

This adapter is a Type 5 Micro Channel adapters. You can install it only in Type 5 adapter system-bus slots. Type 5 adapters are longer and wider than standard Micro Channel adapters. You can install Type 5 adapters in IBM PS/2 Models 85 and 95 and later-version PS/2 MicroChannel servers.

The PC Server Type 8641 (Models MZO, MZV, MZS, MZE, MZL)supports Type 5 Adapters in MicroChannel expansion slots 5 and 6, however, the adapter support bracket must be repositioned. If the server has been shipped with Peermaster adapter installed, the bracket has already been repositioned.

Cabling for 10Base2 Networks

To connect any port of the Quad-B2 PeerMaster adapter to a 10Base2 thin Ethernet cable segment - a thin Ethernet cable segment is the length of the cable between the repeaters - do the following:

• Attach a bayonet connector (BNC) T-connector to the BNC network port at the rear of the computer.
• Attach the end of the coaxial cable to an open end of the T-connector.
• Attach the other end of the cable to an open end of the T-connector at the rear of the next workstation in which a 10Base2 is installed, then, continue making connections to the rest of the workstations.
• Attach a 50-ohm cable terminator at each end of every segment.

NOTE:

• Avoid severe bending of the cable.
• Do not exceed 185 meters (600 feet) of interconnection without using a signal repeater to attach another network segment.
• Do not attach more than one Quad-B2 PeerMaster 10Base2 port to the same 10Base2 network segment.

Use one of the following network operating systems:

• OS/2 LAN Server 2.x or 3.x
• Novell NetWare 3.1 or 4.0x

The PeerMaster Server Adapter Option Diskette is shipped with the PeerMaster Server Adapter options. The diskette contains the following:

• Device drivers
• Setup programs
• NetFinity enablers
• Diagnostic programs
