WARNING:
Before inserting or removing the NIC from
the server, turn off the power to the server.
■
Check the NIC installation. Make sure that the board is
seated correctly in the slot. Check for specific hardware
problems, such as broken traces or loose or broken
solder connections.
■
Inspect all cables and connections. Check the length
and rating of the cable. Make sure that the cable
segment is compliant with the requirements shown
in
Cabling Types and Distances
.
■
The network port may be defective or improperly
configured. Connect the NIC to a different network
port and run the tests again.
■
Check the configuration settings and change them if
they conflict with another device.
■
Make sure that your server is using the latest BIOS.
■
Check the PCI BIOS parameters for the slot where the
NIC is installed.
Table 8

should be set. These parameters may not be
