Ethernet port

The server comes with an integrated Ethernet controller.
This controller provides an interface for connecting to 10-
Mbps or 100-Mbps networks and provides full-duplex (FDX)
capability, which enables simultaneous transmission and
reception of data on the Ethernet local area network (LAN).
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 the server.
Note: The 100BASE-TX Fast Ethernet standard requires
that the cabling in the network be Category 5 or
higher.
The Ethernet (RJ-45) connector has two lights. The Ether-
net 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 on the right. When
this amber light is on, there is activity between the server
and the network. These lights have the same functions as
the Ethernet link-status light and the Ethernet trans-
mit/receive activity light on the information panel (see "Infor-
mation LED panel" on page 10).

Configuring the Ethernet controller

When you connect the server to the network, the Ethernet
controller automatically detects the data-transfer rate
(10Mbps or 100Mbps) on the network and then sets the
controller to operate at the appropriate rate. 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), half duplex (HDX), or full duplex
(FDX). The controller supports half-duplex (HDX) and full-
duplex (FDX) modes at both speeds.
The Ethernet controller is a PCI Plug and Play device. You
do not need to set any jumpers or configure the controller for
your operating system before you use the Ethernet control-
ler. However, you must install a device driver to enable your
operating system to address the Ethernet controller. The
device drivers are provided on the ServerGuide CDs.

Failover for redundant Ethernet

The IBM Netfinity 10/100 Fault Tolerant Adapter is an
optional redundant network interface card (NIC adapter) that
you can install in the server. If you install this NIC adapter
and connect it to the same logical LAN segment as the pri-
mary Ethernet controller, you can configure the server to
support a failover function. You can configure either the
integrated Ethernet controller or the NIC adapter as the pri-
mary Ethernet controller. In failover mode, if the primary
Ethernet controller detects a link failure, all Ethernet traffic
associated with it is switched to the redundant (secondary)
controller. If the appropriate device drivers are installed,
this switching occurs without any user intervention. When
the primary link is restored to an operational state, the Ether-
