Chapter 3. I/O connectors and indicators

The Ethernet (RJ-45) connector has two lights. The Ethernet-link status light is on the
left. When this green light is on, there is an active connection on the Ethernet port.
The Ethernet transmit/receive activity light is on the right. When this amber light is on,
there is activity between the server and the network. These lights have the same func-
tions as the Ethernet-link status light and the Ethernet transmit/receive activity light on
the rear of the server (refer to the User’s Guide on the IBM Documentation CD).
Configuring the Gigabit Ethernet controller
The server comes with an integrated Ethernet controller. This controller provides an
interface for connecting to 10-Mbps, 100-Mbps, or 1000-Mbps networks and provides
full duplex (FDX) capability, which enables simultaneous transmission and reception
of data on the Ethernet local area network (LAN).
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.
Note: See the documentation on the Broadcom NetXtreme Gigabit Ethernet Soft-
ware CD that came with your server for information about configuring the
Ethernet controller.

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