Multiple Chassis with Isolated Backplane
Testing the Installed
Hardware
To test the installed hardware:
1
Make sure that all cards are fully seated into the backplane.
2
Apply power to the chassis by connecting the power cord.
3
Make sure the cooling fans are operating.
The chassis power supply incorporates a load sensing mechanism. If you
do not have any cards in the chassis, the chassis and power supply fans
do not operate.
You can observe the progress of the start routine by watching the
terminal connected to the system’s serial port. See Chapter 8
“Maintenance, Diagnostics, and Troubleshooting”if you experience any
problems.
The start routine verifies that the chassis hardware is functional. Line card
ports are not yet ready to receive calls.
During the power-up process, the NBX 100 tests system components
through the chassis backplane connections. The length of time it takes
the system to power up depends on the number of line cards installed.
The control processor must download software to each line card port,
which takes about two seconds per port. This software download process
occurs every time you turn on the system.
