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.
