same protocol.
The way you test the Ethernet controller depends on which operating system you
are using (see the Ethernet controller device driver README file).
The PCI BIOS IRQ settings are incorrect.
Check the following:
v Determine if the IRQ setting assigned to the Ethernet controller is also assigned to
another device in the IBM Setup Utility program.
Although interrupt sharing is possible 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 persists, call for service.
Check the following:
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.
Check the following:
v Make sure that you are using Category 5 cables when operating the computer at
100 Mbps.
v Make sure that the cables do not run close to noise-inducing sources like
fluorescent lights.
