Determining the Cause of the Alarm Indicator
1.
Turn the PS500 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 PS500 DC and check the red
Alarm
indicator.
If the
Alarm
indicator is lit, either the
PS500 DC is malfunctioning
(replace as described on
page 7-8, Installation
.)
or the problem is caused by the backplane
(contact the manufacturer).
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 main cages, IPx 500M that include a MCP-IPx card:
Turn the PS500 DC power switch OFF again (turn the switch downwards) and
re-insert the MCP-IPx card. Then turn the PS500 DC power switch ON and check
the red
Alarm
indicator. If the red
Alarm
indicator is lit, the MCP-IPx card is
causing the problem and should be replaced.
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.
