Troubleshooting the 100/10 PCI Ethernet Adapter
Note: If you cannot find the problem in the troubleshooting charts,
go to “Testing the System” on page 127 to test the system. If
you already have run the test program, or if running the test
program does not reveal the problem, have the system
serviced.
Troubleshooting the 100/10 PCI Ethernet
Adapter
This section provides troubleshooting information for problems that
might occur when the 100/10 PCI Ethernet Adapter is installed in
the server.
Network Connection Problems
If the adapter cannot connect to the network, check the following:
Make sure the cable is installed correctly.
The network cable must be securely attached at all connections.
If the cable is attached but the problem persists, try a different
cable.
If you set the Ethernet adapter to operate at 100 Mbps, you
must use Category 5 cabling.
If you directly connect two workstations (no hub), use a
crossover cable. Refer to the “Hardware Specifications and
Cabling Information” section in the help file for a list of
recommended cables and information on how to install cabling.
Check the LEDs on the rear of the Ethernet adapter.
The Ethernet adapter has three diagnostic LEDs beside the cable
connector. These lights help indicate whether a problem exists
with the connector, cable, or hub.
– The LNK LED illuminates when the adapter receives a LNK
pulse from the hub. If the LED is OFF, there might be a
bad connector or cable, or a problem with the hub. The
LNK LED is also OFF when you run the diagnostic tests in
the Setup program.
