This book is not intended to solve all levels of troubles. It is limited to troubles that
can be solved by using the Alarm Log, Error Log, trouble-clearing procedures,
maintenance tests, and traditional troubleshooting methods. If the trouble still has
not been resolved, it is the responsibility of the maintenance technician to
escalate the problem to a higher level of technical support. Escalation should
conform to the procedures in the Technical and Administration Escalation Plan.
Organization
This book consists of 2 volumes and a total of 3 chapters:
■
Chapter 1, ‘‘Maintenance for CSI systems’’
describes the system’s design
and maintenance strategy, including circuit packs, how power is supplied to
the system, the various reset and reboot processes (and how these
processes are used to perform maintenance and to recover systems or
subsystems that are out of service), common maintenance tasks (including
removing and installing circuit packs, removing and restoring power,
system backups, upgrading software, and various testing and
troubleshooting procedures), and interpreting circuit pack LEDs.
■
Chapter 2, ‘‘Maintenance Commands’’
explains how to use the
maintenance commands including specific command syntax, typical forms,
and display output.
■
Chapter 3, ‘‘Maintenance Objects’’
has specific troubleshooting and repair
instructions for every maintenance component in the system. This chapter
also contains repair procedures for system-alarmed and user-reported
troubles. For each Maintenance Object (MO), a table lists the alarm level,
hardware error associated with the MO, the associated test that caused the
error, the test sequences and the specific command line entry required to
run the tests, and a brief description of each test. Explanations of error
codes associated with each test are given along with specific maintenance
procedures used to resolve each problem.
The individual maintenance objects are labeled with the name of the MO
exactly as the name appears in the Alarm Log; for example, MAINT (for
Maintenance circuit pack). The only exception is the Common Port Circuit
Pack that uses “XXX-BD” for its maintenance name. The XXX-BD section
contains a set of common tests used by certain circuit packs listed in the
section. The common portion of these circuit packs is the generic hardware
that interfaces with the Time Division Multiplex (TDM) Bus.
