Automatic protection switching and alarm test

............................................................................................................................................................................................................................................................
Description
This section provides the procedures for verifying the 1665 DMX shelf automatic
protection switching.
Note the following:
•
•
•
•
•
•
A properly grounded ESD wrist strap MUST be worn when handling circuit packs.
Unterminated optical connectors may emit laser radiation. Do not view beam with
optical instruments.
Main OLIU switching test
Use this procedure to test the following Main OLIU circuit packs in a UPSR (default)
configuration:
............................................................................................................................................................................................................................................................
5 - 8
These tests do NOT simulate circuit pack failures.
The tests will verify proper alarm reporting and LED indications when circuit
packs are removed.
All protected circuit packs will be tested.
A properly grounded wrist strap must always be worn while handling circuit
packs.
This test is performed with the 1665 DMX shelf optically looped back on itself
(that is, with the IN of the OLIU M1 looped to the OUT of the OLIU M1, and the
IN of the OLIU M2 looped to the OUT of the OLIU M2).
Prior to performing each test, the shelf under test must be clear of all alarms (that
is, only green LEDs are lit).
CAUTION
Laser Safety
When connecting fiber loops between the IN and OUT ports on optical circuit
packs, always connect to the IN port first and then the OUT port. This will
prevent any optical radiation from being present at the fiber end.
CAUTION
