Problem Isolation
Once you have determined that a problem exists, perform the following steps to isolate
the problem for repair:

Evaluate the alarms and isolate the problem to the extent possible.
3. Review the slot configuration and look at the individual ports. Evaluate any
information to further isolate the problem.
