Determining the Cause of the Alarm Indicator
1.
Turn the PS19 DC power switch OFF (turn the switch downwards).
2.
Disconnect the expansion cable(s) connected to the relevant cage.
3.
Remove all cards from the relevant cage so that they protrude from the cage by
approximately 1 inch (2.5 cm).
4.
Turn ON the PS19 DC and check the red Alarm indicator.
If the Alarm indicator is lit, either the PS19 DC is malfunctioning or the
problem is caused by the backplane. Replace the PS19 DC unit.
If the Alarm indicator is not lit, the unit is functioning properly and the alarm
is being caused by one of the cards.
5.
For cages that include common control cards (see table below).
To determine which control card is causing the problem, turn the PS19 DC power
switch OFF again (turn the switch downwards) and re-insert the first control card.
Then turn the PS19 DC power switch ON and check the red Alarm indicator.
Continue this process, adding one common control card at a time, and turning
OFF the PS19 DC power switch before inserting each card. Turn the PS19 DC
power switch ON and check the red Alarm indicator after inserting each card. If
the red Alarm indicator is lit, the last card inserted is causing the problem and
should be replaced.
Turn the PS19 DC power switch OFF, insert the common control cards (MEX-IP2,
HDC, or PX). Then turn the PS19 DC power switch ON and check the red Alarm
indicator once again. If the red Alarm indicator is off, the problem is caused by
one of the cards that was removed.
6.
To determine which shared service and peripheral card is causing the problem,
insert the cards into their appropriate slots, one at a time, beginning from the right
side of the cage. Ensure that the card’s rear panel connectors engage properly with
the backplane and that they initialize properly.
If the Alarm indicator lights when one of the cards is inserted, then that card is
faulty.
