Auxiliary alarm lights

When an alarm condition occurs, any of the six auxiliary
addition to the main alarm light, to help diagnose the alarm condition. The following sections
describe the six auxiliary alarm lights.
5.7.4.1
The red external alarm (labeled EXT ALARM) light switches on to indicate that an alarm
condition has triggered the built-in relay outputs to turn on any externally installed alarms
such as lights or bells.
The external alarm is connected to the matrix through the 9-pin D-type connector on the
matrix's rear panel labeled Alarm I/O.
5.7.4.2
The red Temp (temperature) alarm light switches on to indicate one or both of the
following:
• The active CPU card has detected a temperature in the matrix above a threshold.
• One of two CPU cards has been removed from the matrix.
Note: This feature only operates if there are two CPU cards installed in the matrix. If there is only
one CPU card, the Temp alarm light does not switch on if the card is removed.
5.7.4.3
The red fan-fail alarm light illuminates when either fan in the power-supply module stops
rotating correctly.
5.7.4.4

If a DC output or AC input to the first power supply drops too low, the

switches on to indicate the same condition. One of the green power supply lights may then
switch off to help indicate the source of the trouble.
Note: The PSU1 fail light only works if the first power supply is plugged into the matrix's midplane
from inside the matrix.
A temperature sensor inside the power supply senses if the power supply overheats, and
switches on the second matrix cooling fan. The
the active CPU card, not a power supply, has overheated.
