Maintenance and troubleshooting
Power supply failure
When a power supply is operating properly, its status LED is green. If not, follow these steps to
troubleshoot the power supply:
1.
Check for overheating. Overheating can cause a power supply to enter the protection state.
Make sure the switch is well ventilated.
2.
Check for loose power cord connection, and reconnect the power cord. If the power cord is
broken, replace it.
3.
Verify that the power supply is fully seated in the slot.
4.
Verify that the power source is supplying power at the correct voltage.
5.
If the other power supply slot is empty, plug the power supply into the empty slot to check for
an operating anomaly.
6.
Plug a new power supply of the same model into the same slot, and connect it to the same
power input end. If the new power supply can work properly, the old power supply has failed.
Contact HP technical support to replace the old power supply.

If the problem persists, contact HP for help.
