Features

The IBM Quad-BT (10Base-T) 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 10Base-T Networks

Two types of network cables may be connected to the Quad-BT PeerMaster adapter: straight-through and crossover.

• Straight-Through

Use straight-through cables when connecting your adapter to an external 10Base-T concentrator hub.

• Crossover

Use crossover cables to directly connect your adapter to another 10Base-T device, such as a workstation, server, or another adapter. Crossover cables create dedicated segments. A dedicated segment is two point-to-point devices connected to a dedicated link.

Ensure that you do not externally join ports of adapters (using bridges, switches, or concentrators).

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
