Power Management Unit Tests

Control Tests
164 Part H: Diagnosing
The Service Kit lets you test aspects of the PMU and monitor additional details
of its operation.
The Control Tests form lets you simulate a mains failure. You can also check
that the fan, the fault LED, and the auxiliary output are working.
Simulating Mains Failure
The Control Tests form lets you simulate a mains failure so that you can test the
BSS's battery backup and the PMU's DC-DC converter.
Important: This test affects any other base station in the BSS.
Important: This test will shut the whole BSS down if there is no
backup power supply.
To simulate mains failure
1. Select Diagnose > Power Management > Control Tests.
2. Click Start Test at the bottom of the Control Tests form.
3. Click Mains Failure Test.
4. Check that power to the PA and the Reciter/control panel stays on.
Testing the Fan
You can ask the base station to turn the PMU fan on and off; this tests the fan
and its control circuitry.
