2.1 General Information
When an UNIVERGE SV8100 system is first powered up, an
initialization is performed. During this process the CD-CP00-US
(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.
2.2 Before Initializing
The technician must follow these steps before initializing the
system.
2.2.1 Cable Connections
All wiring for power supplies or flat cable connectors
should be checked for solid connections.
