114 Remote IPE maintenance
Once the cause is identified, correct the problem by replacing the defective
card or Fiber Remote Multi-IPE Interface unit, connecting accidentally
disconnected cables, or correcting the system software problem.
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 Multi-IPE
Interface units at both sides of the fiber-optic link. The 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 Multi-IPE
Interface unit as an integral part of the local system.
It also describes how to maintain and troubleshoot the Superloop
Network and the Peripheral Controller cards dedicated to the Remote IPE
operation.
