• Check for operating system-specific causes for the problem.
• Make sure that the device drivers on the client and system are using the same
protocol.
• Test the Ethernet controller.
The way you test the Ethernet controller depends on which operating system you
are using (see the Ethernet controller device driver README file).
Ethernet controller troubleshooting chart
You can use the following troubleshooting chart to find solutions to 10/100 Mbps
Ethernet controller problems that have definable symptoms.

Ethernet controller
problem
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 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.
Ethernet Link Status light
does not light. Check the following:
• Make sure 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 hum 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 your also manually
configure the speed.
• Run diagnostics on the LEDs.
If the problem remains, call for service.
The LAN activity light does
not light (when available). 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.
