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.

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 Chapter 3.

Configuring the Ethernet controller

If a conflict exists, one or more of the following conditions might

exist:

The system cannot load the operating system.

The system does not work.

An application program does not operate, or it returns an error.

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
