FAIL The -48V is out of tolerance.
1. Use the status environment command to check the voltages: -
48V (+/- 8%) (- 44.2 to 51.8 V)
2. If redundant power supplies are present, there may be a problem
with the backplane. Verify that each power supply can detect the
problem by using the recycle carrier command, specifying the
slot number of the power supply to be shut down. Refer to the notes
and cautions for this command in Maintenance Commands
Reference (03-300191) before executing the recycle carrier
command.
3. Replace the power supply.
4. If the problem persists, check the backplane for shorts.

FAIL The fan voltage is out of tolerance.
1. Use the status environment command to check the voltages:
+12/14 V (+11.4 to +15 V)
2. If redundant power supplies are present, there may be a problem
with the backplane. Verify that each power supply can detect the
problem by using the recycle carrier command, specifying the
slot number of the power supply to be shut down. Refer to the notes
and cautions for this command in Maintenance Commands
Reference (03-300191) before executing the recycle carrier
command.
3. Replace the power supply.
4. If the problem persists, check the backplane for shorts.
PASS The power supply voltage test passes.
NO
BOARD
Power supply is administered but not detected.
1. Verify that the power supply is plugged in.
2. Replace the power supply.
1. The values of these failure codes might be added together. For example, a value of 3 indicates that both
the +5V and the -5V are out of tolerance or a value of 15 indicates that all four voltages are out of
tolerance.
