Data is incorrect or
sporadic.
The Ethernet
controller stopped
working when
another adapter was
added to the server.

Suggested Action
The PCI BIOS interrupt settings are incorrect.
Check the following:
•
Determine if the 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.
Check the following:
•
Make sure that you have loaded the network device drivers.
•
The network might be idle. Try sending data from this
workstation.
•
Run diagnostics on the LEDs.
•
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:
•
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.
Check the following:
•
Make sure that the cable is connected to the Ethernet controller.
•
Make sure that your PCI server BIOS is current.
•
Reseat the adapter.
•
Determine if the 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
