cause is identified, the problem can be corrected by replacing the defective
card, connecting accidentally-disconnected cables, or correcting the
software problem.
CS 1000M Large Systems and Meridian 1 Large Systems provide
built-in self-diagnostic indicators and software and hardware tools.
These diagnostic facilities simplify system troubleshooting and reduce
Mean-Time-To-Repair (MTTR).
This document focuses on the maintenance of Fiber Remote IPE
equipment at the remote site and in the local system. It is assumed that
local non-Fiber Remote IPE functions were operating operate correctly
before beginning to diagnose Fiber Remote IPE problems.
System installation and maintenance guide sections of Communication
Server 1000M and Meridian 1 Large System Maintenance (NN43021-700)
() describe how to maintain the entire system. This section describes how
to maintain the Fiber Remote IPE equipment as an integral part of the local
system.

Diagnostic tools

Diagnostic tools are used to troubleshoot problems in the system, including
problems with the Fiber Remote IPE. When diagnosing Fiber Remote IPE
problems, it can be necessary to use more than one tool.

Hardware diagnostic tools

Hardware diagnostic tools consist of:
•
card self-tests
•
LED indicators
•
display codes
•
enable/disable switches
Self-test
A self-test is automatically performed by each Fiber Remote IPE card:
•
when the card is inserted in an operating system module
•
when the card is enabled
•
when the system is powered up or reset.
A self-test can also be performed on a card using software commands.
