LED Test
Description
This test verifies proper operation of all the LEDs on the DDM-2000 OC-12 shelf.

shelf and replace the faulty unit.
NOTE:
If the shelf is not fully equipped, move circuit packs around and repeat the test.
Test all circuit pack positions.

The DDM-2000 OC-12 will respond with "In Progress ...."for the duration of
the test and will issue a prompt < when the test has completed. All LEDs on the shelf
under test should light for 10 seconds, then extinguish for 10 seconds. Then the proper
LEDs will light to indicate the shelf’s current status.
Local Equipment Test
Description
This test verifies proper operation of the circuit packs and the circuit pack positions
which are equipped in the DDM-2000 OC-12 shelf. The shelf must successfully pass
this test before testing any other feature of the DDM-2000 OC-12.
NOTE:
After completing the local equipment test, isolate and replace any failed units. If
any units are replaced, repeat the LED test and local equipment test until both
tests pass without failures.
