Configuring the Ethernet controller
If a conflict exists, one or more of the following conditions might
exist:
Ÿ
The system cannot load the operating system.
Ÿ
The system does not work.
Ÿ
An application program does not operate, or it returns an error.
Ÿ
Screen messages indicate that a memory-address conflict exists.
Note: Start the Configuration/Setup Utility program to view the
addresses that are used by your system board functions.
The best way to resolve memory-address conflicts is to change the
addresses that are used by the application program or the device
driver. You can use the Configuration/Setup Utility program to
view and change addresses.
Configuring the Ethernet controller
Your Netfinity 3000 server 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
your server. When you connect your 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 requiring
software intervention. The controller supports half-duplex (HDX)
and full-duplex (FDX) modes at both speeds.
However, auto-negotiation works only if the hub or switch to which
your 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 3000 server 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, your server must have
