Installation and Reference for the BayStack 22 PC Card Adapter

Hardware Issues

Perform the following tasks to check for hardware problems:

Verify that you are using the correct cables and the correct cable lengths, as described in “Cable Requirements ” on page 1-6.

Make sure the media coupler is firmly connected to the network card and to a network device.

Use a different port on the network device.

Verify that the BayStack 22 network card is fully and firmly seated in the slot connector in the computer. Check the connector edges of the card for damage.

Replace the network card in question with a network card that you are sure functions properly. Run generic network interface card diagnostic tests.

Install the network card in question into another computer and run the tests again.

Remove all other network cards from the computer and run the tests again.

If the verification/diagnostic run is not normal, there is probably an interrupt number conflict. You must manually resolve the conflict by running a CMOS Setup utility after you have reinstalled the expansion cards.

Software Issues

Perform the following tasks to check for software problems:

Verify that the proper driver is loaded, as explained in Chapter 3, “ Software Installation.” Be sure you followed the directions for the operating system you are running on the computer.

Check that the new configurations match the configurations of the network device if you have manually configured the speed or mode of the network card. Nortel Networks recommends setting the network card to autonegotiation when installing the network driver.

Verify that the PCMCIA slot in the computer is an enabled bus-master slot. Some computers may require that you configure the PCMCIA slot to enable bus mastering. Refer to your computer manual for information about the PCMCIA BIOS setup program.

Verify that your BIOS software correctly supports the PCMCIA Local Bus Specification, version 2.0 or later. Upgrade your BIOS software if needed.
