System Maintenance

SECTION 1 INTRODUCTION
The technician can use this book to troubleshoot and diagnose problems during and after system
installation. The troubleshooting flow charts and general test procedures help the technician identify
possible causes of the problem by defining the problem area.
Using the System Data Upload/Download feature, all System Programming and Speed Dial data can be stored
on disk for safe keeping. After all System Programming is completed, it should be downloaded to a disk for
backup. When system memory fails, this data on the disk can be uploaded and the memory restored.
SECTION 2

OPERATIONAL TEST PROCEDURES

General Information
When an UNIVERGE SV9100 system is first powered up, an initialization is performed. During this process the
GCD-CP10 (CPU), located in the first chassis, scans each interface slot to determine the hardware
configuration used. This information is stored in the resident system program memory with the system
default values. This section provides test procedures that are used before, during, and after the initialization
process.
Before Initializing
The technician must follow these steps before initializing the system.
Cable Connections
All wiring for power supplies or flat cable connectors should be checked for solid connections.
