Verifying power supply operation
Perform the following tasks to verify operation of the power supply:
1. Check the LED indicator on the power supply. The LED patterns may temporarily change during POST and other diagnostic
tests. For information on interpreting LED patterns, refer to Interpreting power supply LEDs on page 110. Be sure to check all
the power supply modules.
2. Check the power supply status by entering the following commands:.
The power supply status displays OK, Absent, or Faulty. If a power supply displays absent or faulty, contact the device supplier
to order replacement parts. Both physically absent or faulty could also be the result of the power supply not being properly
seated or being turned off.
•
psShow - Displays the status of each power supply as OK, Absent, or Faulty. If a power supply displays absent or faulty,
contact the device supplier to order replacement parts. Both physically absent or faulty could also be the result of the power
supply not being properly seated or being turned off.
