4.5 Monitor the System Displays and LEDs
On power up, the DECNIS 600 automatically tests each module and then tests
the operation of the installed system:
1. Module self-test
The DECNIS 600 activates a module self-test on each card that is installed
and enabled. The module self-test checks the card for faults.
2. System self-test
When each card has completed its module self-test, the DECNIS 600 runs
a system self-test. This test checks that each card can interact with the
rest of the system. It then runs a diagnostic check to test the operation of
the whole system.
