Last week, we lost power to the building and the generator kicked in as expected. However, one of the server racks with the Dell UPS 5600R lost complete power. The error messages on the UPS were 1) Rectifier Fault and 2) DC Link Over Voltage. I was able to restore power to the rack by pressing the power button several times on the UPS.
We have tested the UPS by turning off the circuit breaker to the UPS to ensure that the UPS kicks in automatically and it did. We can't figure out why it failed that last time...
Do you know what these error messages mean? Is there a way to check the logs on the UPS?
Thank you
