Automatic Protection Switching and Alarm Test
Description
This section provides the procedures for verifying the Metropolis
®
DMXplore shelf automatic protection switching.
Note the following:
•
These tests do NOT simulate circuit pack failures.
•
The tests will verify proper alarm reporting and LED indica-
tions when circuit packs are removed.
•
This test assumes that two OLIU circuit packs have been
installed.
•
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 Metropolis
®
DMXplore shelf
optically looped back on itself (that is, with the
OUT
of the
OLIU Main 1 looped to the
IN
of the OLIU Main 1, and the
OUT
of the OLIU Main 2 looped to the
IN
of the OLIU Main
2).
•
Prior to performing each test, the shelf under test must be
clear of all alarms (that is, only green LEDs are lit).
CAUTION
...........................................................................................................................................................................
A properly grounded ESD wrist strap MUST be worn when
handling circuit packs.
WARNING
Unterminated optical connectors may emit laser radiation. Do
not view beam with optical instruments.
