h1susauxey front end computer has a failed power supply
Fil, Jonathan, Erik, Dave:
At EY Fil found h1susauxey has its front panel FAIL LED lit. He tracked the issue down to a failed power supply. This is a redundant dual power supply system.
Strangely this system is not beeping, which is the default behaviour if a power supply unit is inserted but not operational.
The IPMI shell confirms that the system has correctly identified the failure:
ipmi sensor output:
OK | (2751) PS1 Status | Presence detected |
Fail | (2818) PS2 Status | Power Supply Failure detected |
WP11652
Erik replaced the failed power supply with a good spare, status is good
h1susauxey: OK | (2751) PS1 Status | Presence detected |
h1susauxey: OK | (2818) PS2 Status | Presence detected |
