Cabling Problems

The following may be symptoms of cabling problems:

• Network does not come up

• X.25 link layer does not come up, or does not stay up

• The message xmit hung appears in the console

• No data is being sent or received

Check the following:

1. Make sure you are using the correct type of cable. Refer to Appendix A, Cabling for cabling diagrams.

2. Make sure all cables are properly seated.

3. If you are operating over an LAPB link, make sure that you are using a cable that is designed for synchronous use. If you have a spare cable, replace your existing cable and retry the connection.
