Troubleshooting
the Installation
Follow these troubleshooting tips if you have trouble installing or configuring your
NIC,
or if the NIC installation fails.
■
Make sure that the NIC is correctly installed in a PCI slot. Check for specific
hardware problems, such as broken traces or loose or broken solder
connections.
Go to:
NIC Installation
.
■
Inspect all cables and connections. Check the length and rating of the cable.
Make sure that the cable segment is compliant with the requirements for a
3CR990 NIC.
Go to:
Cabling Requirements
.
■
Make sure that you are using the latest BIOS for your PC. If your BIOS has not
been upgraded in the previous 12 months, contact your PC manufacturer to
obtain the current version of your BIOS software.
■
Run the NIC diagnostics tests.
Go to:
Running Diagnostics Programs
.
■
Replace the failed NIC with a working NIC and run the diagnostics tests again,
using the same option settings as those used on the failed NIC. If the working
NIC passes all tests, the original NIC is probably defective. For information on
product repair
Go to:

CAUTION:
Before inserting or removing the NIC from the PC, turn the PC power
off and unplug the power cord.
