Ethernet controller problem

 

Suggested Action

 

 

The server stops running

The PCI BIOS interrupt settings are incorrect.

when loading device drivers.

Check the following:

 

 

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.

 

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

 

 

World Wide Web.

 

Run the network diagnostic program.

 

If the problem remains, call for service.

 

 

The LAN activity light does

Check the following:

not light.

Make sure that you have loaded the network device drivers.

 

 

The network might be idle. Try sending data from this workstation.

 

Run diagnostics on the LEDs.

 

The function of this LED can be changed by device driver load parameters. If

 

 

necessary, remove any LED parameter settings when you load the device drivers.

 

 

Data is incorrect or sporadic.

Check the following:

 

Make sure that you are using Category 5 cabling when operating the server at 100

 

 

Mbps.

 

Make sure that the cables do not run close to noise-inducing sources like

 

 

fluorescent lights.

 

 

The Ethernet controller

Reseat the adapter.

 

Determine if the interrupt (IRQ) setting assigned to the Ethernet adapter 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

Try a different connector on the hub.

 

 

Reinstall the device drivers. Refer to your operating-system documentation and

 

 

to the ServerGuide information.

 

If the problem remains, call for service.
