Configuring the Ethernet controller
The Netfinity 5000 comes with an Ethernet controller on
the system board. The Ethernet controller provides
10BASE-T and 100BASE-TX support through the RJ-45
connector on the back of the server.
When you connect the server to the network, the Ethernet
controller 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. 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). This process is also known as
auto-negotiation. This auto-negotiation occurs without
software intervention. The controller supports half-duplex
(HDX) and full-duplex (FDX) modes at both speeds.
Auto-negotiation works only if the hub or switch to which
the server is connected also supports auto-negotiation. If
the hub or switch does not support auto-negotiation, the
speed (10 Mbps or 100 Mbps) will still be detected
correctly, but half-duplex mode will always be selected. A
full-duplex switch that does not support auto-negotiation
will not attach to the Netfinity 5000 in full-duplex mode.
In this case, if you want the network to operate in
full-duplex mode, you must manually override the settings
to obtain a full-duplex connection. To do this, the server
must have a device driver that supports manual overrides.
Use the ServerGuide CDs to install this device driver.
Refer to the “ServerGuide and Netfinity Manager
Information” section of this
Server Library for instructions
on installing device drivers. The ServerGuide CDs contain
IBM Update Connector, a dial-up
1 program that keeps the
BIOS and device drivers current. Verify that you have
installed the appropriate device driver. Also, refer to the
Ethernet documentation for additional information on
operating modes, manual overrides, and device drivers.
Attention:
Ÿ
The 10BASE-T Ethernet and the 100BASE-TX Fast
Ethernet cabling in the network must be Category 5
or higher to meet various standards, including
electromagnetic compatibility.
Ÿ
You must install a device driver to enable the
operating system to address the Ethernet controller.
Use the ServerGuide CDs to install this device driver.
