BOARD
Description and recommendation
Power supply is administered but not detected.
1. Verify that the power supply is plugged in.
2. Replace the power supply.
1. It is unlikely that these failure codes will occur when redundant power supplies are present because each
power supply is measuring the backplane voltage rather than the power supply voltage.
Power Supply Voltage Test (#1536)
The TN2312BP IPSI scans the status of each 655A power supply on the serial bus every 5
seconds. This test returns the status of the most recent scan of the 655A DC output voltages.
This test runs on POW-SUP (Power Supply).
