You must approach problem identification systematically. A problem can
have more than one cause. To isolate the cause, a knowledge of MIVS
operation is required. Once you identify the cause, you can correct the
problem by replacing the defective card, connecting accidentally
disconnected cables, or correcting the software security problem.
The system and the MIVS provide built-in self-diagnostic indicators and
software and hardware tools. These diagnostic facilities simplify system
troubleshooting and reduce the Mean Time To Repair (MTTR).
This document focuses on the maintenance of the MIVS equipment. It
requires that the system operate correctly before you start diagnosing the
MIVS problems. Large System: Maintenance (553-3021-500) describes how
to maintain the entire system. This chapter describes how to maintain the
MIVS as an integral part of the system.
