Description FRU/action
The server stops
running when loading
device drivers.
The PCI BIOS interrupt settings are incorrect.
v Determine whether the interrupt (IRQ) setting that is 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.
v
Make sure that you are using the most recent device driver that is available from the
World Wide Web.
v
Reseat or replace the adapter.
The Ethernet link status
LED does not work.
v
Make sure that the hub is turned on.
v Check all connections at the Ethernet controller and the hub.
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 Reseat or replace the adapter.
The Ethernet
transmit/receive activity
LED does not work.
v Make sure that you have installed the network device drivers.
v
The network might be idle. Try sending data from this server.
Data is incorrect or
sporadic.
v
Make sure that you are using Category 5 or higher cabling when operating the server at
100 Mbps or at 1000 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.
v Make sure that the cable is connected to the Ethernet controller.
v
Make sure that the PCI system BIOS code is current.
v Reseat the adapter.
v
Determine whether the interrupt (IRQ) setting that is assigned to the Ethernet adapter is
also assigned to another device in the system. Use the Configuration/Setup Utility
program to determine whether this is the case.
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 that is
assigned to the Ethernet adapter or the other device.
v
Reseat or replace the adapter.
The Ethernet controller
stopped working without
apparent cause.
v
Try a different connector on the hub.
v Reinstall the device drivers. See the operating-system documentation and the
ServerGuide information.
v Reseat or replace the adapter.
Ethernet controller messages
The integrated Ethernet controller might display messages from certain device
drivers. The latest available information concerning these messages is at the IBM
Support Web site at http://www.ibm.com/support/.
