• Reinstall the new software or new device. Troubleshooting the Ethernet controller This section provides troubleshooting information for problems that might occur with the 10/100 Mbps Ethernet controller. Network connection problems If the Ethernet controller cannot connect to the network, check the following: • Make sure that the cable is installed correctly. The network cable must be securely attached at all connections. If the cable is attached but the problem persists, try a different cable. If you set the Ethernet controller to operate at 100 Mbps, you must use Category 5 cabling. If you directly connect two workstations (without a hub), or if you are not using a hub with X ports, use a crossover cable. Note: To determine whether a hub has an X port, check the port label. If the label contains an X, the hub has an X port. • Determine if the hub supports auto-negotiation. If not, try configuring the integrated Ethernet controller manually to match the speed and duplex mode of the hub. • Check the Ethernet controller lights on the operator information panel. These lights indicate whether a problem exists with the connector, cable, or hub. - The Ethernet Link Status light illuminates when the Ethernet controller receives a LINK pulse from the hub. If the light is off, there might be a defective connector or cable, or a problem with the hub. - The Ethernet Transmit/Receive Activity light illuminates when the Ethernet controller sends or receives data over the Ethernet Network. If the Ethernet Transmit/Receive Activity light is off, make sure that the hub and network are operating and that the correct device drivers are loaded. - The Ethernet Speed 100 Mbps light illuminates when the Ethernet controller LAN speed is 100 Mbps. • Make sure that you are using the correct device drivers, supplied with the server. • Check for operating system-specific causes for the problem. • Make sure that the device drivers on the client and server are using the same protocol. • Test the Ethernet controller. How you test the Ethernet controller depends on which operating system you are using (see the Ethernet controller device driver README file). 28 Netfinity 6000R Type 8682 Models 1RY, 2RY

Troubleshooting the Ethernet controller

This section provides troubleshooting information for prob-

lems that might occur with the 10/100 Mbps Ethernet con-

troller.

Network connection problems

If the Ethernet controller cannot connect to the network,

check the following:

•

Make sure that the cable is installed correctly.

The network cable must be securely attached at all

connections.

If the cable is attached but the problem

persists, try a different cable.

If you set the Ethernet controller to operate at 100

Mbps, you must use Category 5 cabling.

If you directly connect two workstations (without a hub),

or if you are not using a hub with X ports, use a cross-

over cable.

Note:

To determine whether a hub has an X port,

check the port label.

If the label contains an

the hub has an X port.

•

Determine if the hub supports auto-negotiation.

If not,

try configuring the integrated Ethernet controller manu-

ally to match the speed and duplex mode of the hub.

•

Check the Ethernet controller lights on the operator

information panel.

These lights indicate whether a problem exists with the

connector, cable, or hub.

—

The Ethernet Link Status light illuminates when

the Ethernet controller receives a LINK pulse from

the hub.

If the light is off, there might be a defec-

tive connector or cable, or a problem with the hub.

—

The Ethernet Transmit/Receive Activity light illumi-

nates when the Ethernet controller sends or

receives data over the Ethernet Network.

If the

Ethernet Transmit/Receive Activity light is off,

make sure that the hub and network are operating

and that the correct device drivers are loaded.

—

The Ethernet Speed 100 Mbps light illuminates

when the Ethernet controller LAN speed is

100 Mbps.

•

Make sure that you are using the correct device drivers,

supplied with the server.

•

Check for operating system-specific causes for the

problem.

•

Make sure that the device drivers on the client and

server are using the same protocol.

•

Test the Ethernet controller.

How you test the Ethernet controller depends on which

operating system you are using (see the Ethernet con-

troller device driver README file).
