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-

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.
