Table 4 provides solutions to 10/100 Mbps Ethernet controller problems that have
the described symptoms.

Ethernet controller problem Suggested Action
The appliance stops running

Ethernet Link Status light
does not light.
– 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 bad 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.

protocol.
How you test the Ethernet controller depends on which operating system you are
using (see the Ethernet controller device driver README file).
The PCI BIOS interrupt settings are incorrect.
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.
v Make sure that you are using the most recent device driver available from the
World Wide Web.
v Run the network diagnostic program.
If the problem remains, call for service.
Check the following:
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.
If the problem remains, call for service.
