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.

vDetermine 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.

vCheck 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.

vMake sure that you are using the correct device drivers, supplied with the server.

vCheck for operating system-specific causes for the problem.

vMake sure that the device drivers on the client and server are using the same protocol.

vTest 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).

Ethernet controller problem

Suggested Action

 

 

The server stops running

The PCI BIOS interrupt settings are incorrect.

when loading device drivers.

Check the following:

 

 

v Determine if the interrupt (IRQ) setting assigned to the Ethernet controller is also

 

assigned to another device in the Configuration/Setup Utility program.

 

Although interrupt sharing is allowed for PCI devices, some devices do not function

 

well when they share an interrupt with a dissimilar PCI device. Try changing the

 

IRQ assigned to the Ethernet controller or the other device. For example, for

 

NetWare Versions 3 and 4 it is recommended that disk controllers not share

 

interrupts with LAN controllers.

 

v Make sure that you are using the most recent device driver available from the

 

World Wide Web.

 

v Run the network diagnostic program.
