RMC Power/Fan Query Test (#77)
This test queries the Processor circuit pack for the status of the cabinet sensors in
the Avaya IP600 cabinet. Only one alarm lead is supported by this cabinet type to
indicate a power, temperature, 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.

Result Description / Recommendation
1000 ABORT System resources required to run this test are not available.
1. Retry the command at 1-minute intervals up to 5 times.
2000 ABORT Response to the test request was not received within the allowable time period.
2029 ABORT Internal system error.
1. Retry the command at 1-minute intervals up to 5 times.
1 FAIL There is a fan, temperature, power, or voltage problem in one or more of the
cabinets. The power supply’s LEDs may indicate the problem’s source.
1. If none of the fans are running, then:
a. Verify 8- to 14-Volt DC power is available to the fan units by checking
the wiring connector.
— If there is 8- to 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 not, then the power unit’s fan output is defective or thermally shut
down. Let the power unit cool, and recycle AC input power. If no
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 every fan can be started, wait 5 minutes and rerun the test. If the test fails
again, proceed to Step 4 or 5 as applicable.
4. If the fans are not at high speed, measure the cabinet’s temperature at the
air intake and the air exhaust at the top of the cabinet.
a. If the 5- to 60
0
-C criteria is met, there is a problem with the fans that is
preventing the fans from operating at high speed. Replace the fans. If
the fans run at high speed, wait 5 minutes to give the cabinet time to
cool down and, rerun the test. If the problem persists, go to step 5.
If not, the Processor circuit pack is incorrectly reporting this condition.
Look for and resolve every error on these MOs first, then rerun the test.
