xSeries 440:Troubleshooting Guide
If you directly connect two workstations (without a hub), or if you are not using a
hub with X ports, use a crossover cable.
Note: To determine whether a hub has an X port, check the port label. If the label
contains an X, the hub has an X port.
• Determine if the hub supports auto-negotiation. If not, try configuring the
integrated Ethernet controller manually to match the speed and duplex mode of
the hub.
• Make sure that you are using the correct device drivers, supplied with your server.
• Check for operating-system-specific causes for the problem.
• Make sure that the device drivers on the client and server are using the same
protocol.
• Test the Ethernet controller.
How you test the Ethernet controller depends on which operating system you are
using (see the Ethernet controller device driver README file).

problems that have definite 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 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. 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.
Data is incorrect or sporadic. Check the following:
• Make sure that you are using Category 5 cabling when operating the server at 100
Mbps.
• 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:
• Make sure that the cable is connected to the Ethernet controller.
• Make sure that your PCI system BIOS is current.
• Reseat the adapter.
• 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.
