Testing the module power supply
Use this procedure to test module power supplies and ringing generators and their interface to the system monitor. This procedure should be performed for each power supply at system installation, or whenever a module is installed.
Note: Performing these tests on a single CPU system may cause a sysload. Performing these tests on a dual CPU system may cause an initialization. Disregard INI messages during the tests.
Procedure 59
Testing module power supply
1Verify that the green LED on each power supply is lit and that each red column LED is OFF.
2Set the power supply to OFF. If there is an MPDU in the module, use the associated circuit breaker on the MPDU. If there is a switch on the power supply, use the switch.
•The green LED on the power supply should go out.
•The red column LED should light.
•The system terminal should display PWR0002 and BSD090.
Note: If the power supply is in an IPE Module, XMI messages may be generated.
•The system terminal should then display BSD000.
3Set the power supply to ON.
•The green LED on the power supply should light.
•The red column LED should go out.
•The system terminal should display PWR0000.
