operating system to address the Ethernet controller. The device drivers are provided
on the ServerGuide
When you connect your server to the network, the Ethernet controller automatically
detects the data-transfer rate (10 Mbps, 100 Mbps, or 1000 Mbps) on the network
and then sets the controller to operate at the appropriate rate. In addition, if the
Ethernet ports that your server is connected to support auto-negotiation, the Gigabit
Ethernet controller will set the appropriate duplex state. That is, the Ethernet
controller will adjust to the network data rate, whether the data rate is standard
Ethernet (10BASE-T), Fast Ethernet (100BASE-TX/1000BASE-T), half duplex
(HDX), or full duplex (FDX). The controller supports half-duplex (HDX) and
full-duplex (FDX) modes at both speeds.
For information on configuring your Ethernet controller, see the Broadcom
NetXtreme Gigabit Ethernet Software CD that comes with your server. For updated
information about configuring your Ethernet controller, go to the IBM Support Web
site at http://www.ibm.com/pc/support and navigate to the area for your specific
server type. From this area you can download documentation, the most current
device drivers for your server, and software that supports advanced networking
functions. After downloading, run the downloaded program launch.exe.

High-performance Ethernet modes

Your Ethernet controller supports optional modes, such as teaming, priority packets,
load balancing, fault tolerance, and virtual LANs, which provide higher performance,
security, and throughput for your server. These modes apply to the integrated
Ethernet controller and to the controllers on supported Ethernet adapters.

The following illustration shows the pin-number assignments for the RJ-45 port.
These assignments apply to the 10BASE-T, 100BASE-TX, and 1000BASE-T
devices.

Integrated system management processor (ISMP) interconnect ports

The integrated system management processor (ISMP) ports (ISMP A and B) use a
dual RJ-45 connector to interconnect ISMPs of several servers through an optional
Remote Supervisor Adapter.
Note: ISMP ports (ISMP A and B) are used for the RS-485 interconnect network

Remote Supervisor Adapter in this server. If you install an optional IBM
Remote Supervisor Adapter in this server, you must use the RJ-45 connector
on the adapter for interconnect network communications.
