The following table shows the pin-number assignments for the auxiliary-device
connector on the end of the cable.
Ethernet ports
The server comes with two integrated Ethernet controllers. 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.
Configuring the Ethernet controller: When you connect the server to the network,
the Ethernet controller for that Ethernet port automatically detects the data-transfer
rate (10 Mbps or 100 Mbps) on the network and then sets the controller to operate at
the appropriate rate. In addition, if the Ethernet port that the server is connected to
supports auto-negotiation, the 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), 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 controller. However, you must install a device driver to enable your
operating system to address the Ethernet controllers. The device drivers are provided
on the ServerGuide CDs.
Failover for redundant Ethernet: The IBM Netfinity 10/100 Ethernet Adapter or the
IBM 10/100 Etherjet PCI family of adapters are optional redundant network interface
cards (NIC adapter) that you can install in your server. If you install this NIC adapter
and connect it to the same logical segment as the primary 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 primary Ethernet controller.
In failover mode, if the primary Ethernet controller detects a link failure, all Ethernet
