Ethernet controller problem Suggested Action
Ethernet Link Status light
does not light.
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.
The Ethernet Transmit/
Receive Activity light does not
light.
Check the following:
Note: The Ethernet Transmit/Receive Activity LED illuminates only when data is sent
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
stopped working when
another adapter was added to
the server.
Check the following:
v Make sure that the cable is connected to the Ethernet controller.
v Make sure that the PCI system BIOS is current.
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
stopped working without
apparent cause.
Check the following:
v Run diagnostics for 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.
