Ethernet controller
problems
Suggested action
The server stops running
when loading device drivers. The PCI BIOS interrupt settings are incorrect.
Check the following:
• Determine if the 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/PCI-X devices, some devices do not
function well when they share an interrupt with a dissimilar PCI/PCI-X device. Try
changing the IRQ assigned to the Ethernet controller or the other device.
• 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 Ethernet Link Status
light does not illuminate. Check the following:
• Make sure that the hub is turned on.
• Check all connections at the Ethernet controller and the hub.
• Check the cable. A crossover cable is required unless the hub has an X
designation.
• Use another port on the hub.
• If the hub does not support auto-negotiation, manually configure the Ethernet
controller to match the hub.
• If you manually configured the duplex mode, make sure that you also manually
configure the speed.
• Run diagnostics on the LEDs.
If the problem remains, call for service.
The Ethernet
Transmit/Receive Activity
light does not illuminate. Check the following:
• 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.
Data is incorrect or sporadic. Check the following:
• Make sure that you are using Category 5 cabling when operating the system at 100
Mbps.
• Make sure that the cables are not routed close to noise-inducing sources like
fluorescent lights.
The Ethernet controller
stopped working when
another adapter was added
to the system. Check the following:
• Make sure that the cable is connected to the Ethernet controller.
• Make sure that the PCI-X system BIOS code is current.
• Reseat the adapter.
• Determine if the 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/PCI-X devices, some devices do not
function well when they share an interrupt with a dissimilar PCI/PCI-X device. Try
changing the IRQ assigned to the Ethernet adapter or the other device.
If the problem remains, call for service.
