CABINET (Cabinet Sensors)
Cabinet Temperature Query Test (#122)
This test queries the Processor circuit pack for the status of the cabinet sensors in
the Compact Modular Cabinet. The 650A Power Supply is equipped with thermal
protection that shuts the power supply down if the internal temperature exceeds
the maximum rated safe operating temperature. Only one alarm lead is supported
by this cabinet type to indicate both a power or a fan problem.
This means that a failure of this test can also mean a power problem, not
necessarily just a temperature (fan) problem. Also, alarm leads from multiple
cabinets are tied into one single lead.

period.
Internal system error
1. Retry the command at 1-minute intervals a maximum of 5 times.
There is a fan and/or power problem in one or more of the cabinets. The
LEDs on the power supply may indicate the problem source. Otherwise
follow the procedures below for each cabinet:
1. If none of the fans are running:
a. Verify 8-14 volt DC power is available to the fan units by checking
the wiring connector.
— If there is 8-14 volt DC power at the connector, there should be
power to the fans. If the fans still do not run, replace the fan
assembly.
— If there is no 8-14 volt DC power at the connector, the power unit
fan output is defective or thermally shut down. Let the power unit
cool and recycle AC input power. If not fan output, replace the
power unit. If the fans still do not run, escalate the problem.
2. If only 1 of the fans is not running, replace the fan.
3. If all the fans can be started, wait five minutes and rerun the test. If the
test fails again, go to Step 4 or 5 as applicable.
