Ethernet controller problem

Suggested Action

 

 

Ethernet Link Status light

Check the following:

does not light.

v Make sure that the hub is turned on.

 

v Check all connections at the Ethernet controller and the hub.

 

v Check the cable. A crossover cable is required unless the hub has an X

 

designation.

 

v Use another port on the hub.

 

v If the hub does not support auto-negotiation, manually configure the Ethernet

 

controller to match the hub.

 

v If you manually configured the duplex mode, make sure that you also manually

 

configure the speed.

 

v Run diagnostics on the LEDs.

to or by this Ethernet controller.

 

v Make sure that you have loaded the network device drivers.

 

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

 

v Run diagnostics on the LEDs.

 

v 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:

 

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

 

Mbps.

 

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

 

fluorescent lights.

 

 

The Ethernet controller

Check the following:

stopped working when

v Make sure that the PCI system BIOS is current.

the server.

v Reseat the adapter.

 

v 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 changing the

 

IRQ assigned to the Ethernet adapter or the other device.

 

 

The Ethernet controller

v Try a different connector on the hub.

 

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

 

the ServerGuide information.
