The integrated Ethernet controller is located on PCI bus B (slots 2 and 3) on the
system board. See “Adapter considerations” on page 51 for detailed information
about the PCI buses in your server.
To access the Ethernet port, connect a Category 3, 4, or 5 unshielded twisted-pair
(UTP) cable to the RJ-45 connector on the rear of your server.
Note: The 100BASE-TX/1000BASE-T Fast Ethernet standard requires that the
cabling in the network be Category 5 or higher.
The Ethernet (RJ-45) connector has two LEDs. The Ethernet link LED is on the
right. When this green LED is on, there is an active connection on the Ethernet
port. The Ethernet activity LED is on the left. When this amber LED is on, there is
activity between the server and the network. These LEDs have the same functions
as the Ethernet link LED and the Ethernet activity LED on the rear of the server
(see “Server controls and indicators” on page 4).
For information on configuring the Gigabit Ethernet controller, see “Configuring the
Gigabit Ethernet controller” on page 23 or the Broadcom NetXtreme Gigabit
Ethernet Software CD that comes with the server.

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
communications. These ports become inactive if you install an optional IBM
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.
Cabling the server
Notes:
1. You must turn off the server before connecting any cables to or disconnecting
any cables from the server.
2. See the documentation that comes with your options for additional cabling
instructions. It might be easier for you to route cables before you install certain
options.
