General Information
When an Electra Elite 192 system is first powered up, an
initialization is performed. During this process the CPUB( )-U10
ETU, located in the Basic KSU, 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.
3.2
Before Initializing
The technician must follow these steps before initializing the
system.
3.2.1
Cable Connections
All wiring for power supplies or flat cable connectors
should be checked for solid connections.
3.2.2
AC/DC Power
Check all power with an AC/DC multimeter. (Refer to
Table 9-1 Voltage Measurement
.) Run this test with only
the CPUB( )-U10 ETU and the ESI(8)-U10 ETU installed.
