General Information
When an Electra Elite 48 system is first powered up, an initialization
is performed. During this process, the MBD-U10 Unit, located on
the backplane of the B48-U10 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 10-1 Voltage Measurement
.) Run this test with no
additional interface cards installed.
