Ethernet port
Your 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 your server.
Notes:
1. The 100BASE-TX Fast Ethernet standard requires that the cabling in the network
be Category 5 or higher.
2. If you plan to use the IBM Advanced Appliance Configuration Utility to
configure and manage your appliance, be sure to connect the built-in Ethernet
connector to the same physical network as your systems management console.
Configuring the Ethernet controller
When you connect your 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 controller. 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 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 traffic associated with it is switched to the redundant (secondary) controller.
This switching occurs without any user intervention. When the primary link is
restored to an operational state, the Ethernet traffic switches back to the primary
Ethernet controller. The switch back to the primary Ethernet controller can be
automatic or manually controlled, depending on the setup and operating system.
Note that only one controller in the redundant pair is active at any given time. For
example, if the primary Ethernet controller is active, then the secondary Ethernet
controller cannot be used for any other network operation.
Note: Your operating system determines the maximum number of IBM Netfinity
10/100 Fault Tolerant Adapters that you can install in your server. See the
documentation that comes with the adapter for more information.
