Switch Control Destructive EPN Maintenance Board Interface Test (#325)

This test is destructive.

any FAIL This failure indicates that communications with the Maintenance circui t

pack in the EPN is probably not possible. The EPN Manager I may not be

usable.

1. Run the Short Test Sequence several times to make sure the error is

occurring consistently, run the Long Test Sequence to reset t he Switc h

Control. Sometimes running the Long Test Sequence may clear the

problem. Remember the Long Test Sequence is destructive. Placing

and receiving calls is affected for several seconds.

2. Replace the Netcon circuit pack whenever it is convenient for the

customer (unduplicated system) or right away (High or Critical

Reliability system).

3. The procedure for replacing the Netcon circuit pack is described in

Chapter 6, ‘‘Reliability Systems: A Maintenance Aid’’. The procedure

for doing the same in systems without High or Critical Reliability is

described in Chapter 5, ‘‘Routine Maintenance Procedures’’.

PASS The EPN Maintenance circuit pack interface between the processor and

the Switch Control is working correctly. Test #325 is a mor e thor ough test of

this interface but it is destructive.
