About this Book
555-233-143 xx Issue 1 May 2002
Intended Use
■
As a guide for diagnosing and repairing an S8700 Media Server system for
use by field technicians, remote service personnel, and user-assigned
maintenance personnel
■
As a training manual for teaching technicians how to maintain the system
■
As a reference source on the system’s maintenance capabilities
This document assumes that the technician has a working knowledge of
telecommunications fundamentals and PBX maintenance practices. This
document also assumes that the system was initially installed and tested properly
and brought into service with every fault cleared. Adjuncts and other devices
external to the switch are covered by their own service documentation.
How to Use this Document
Most maintenance sessions involve analyzing the Alarm and Error Logs to
diagnose a trouble source and replacing a component such as a circuit pack. The
information in
Chapter 8, ‘‘Maintenance-Object Repair Procedures’’ will generally
suffice to address these needs. Certain complex elements of the system, such as
fiber links and the packet bus, require a more comprehensive approach. Special
procedures for these elements appear in
Chapter 4, ‘‘Alarms, Errors, and
Troubleshooting’’ .
This document is not intended to solve every level of trouble. When the limits of
these procedures have been reached and the problem has not been resolved, it is
the technician’s responsibility to escalate to a higher level of technical support.
Escalations should conform to the procedures in the Technical and Administration
Plan.
NOTE:
This document is designed to be read online and in paper format. Because
of the large volume of information, additional cross-references have been
added to make it easier to locate information when using the manual online.
