Problem Isolation

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

1. Check to ensure power is available to all modules.

2. Review the LED displays to determine if any module is in an alarm state.

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.

4. Check wiring to ensure connected equipment cables are properly installed and

secured. Do not assume the problem is internal to the Broadmore 1750.
