I have a PowerEdge R320 that displays PSUA0016 PSU 1 is absent. This is impossible since it only has one power supply and powers up fine. Things I have tried:
1. Clear bios of errors reboot
2. Run Lifecycle controller to test and clear errors. It states all errors are cleared an nothing to report.
3. Run Centos OS with Openmanagment . When I run option 3 Clear all ESM errors it gives error about the Serial Number and appears to do nothing. Shut down system remove power and hold power button for 10 seconds.
The crazy thing is now I have intrusion detection on the LCD that wont go away after inspecting the power cables on the inside.
Thanks for any advice.
