We have a SYS-1028U-TNRT+, but one of the redundant power supplies has a blinking green status LED. If power is removed from the non-blinking PSU, the server loses power. Plug in power to both PSUs to power on the system. Then remove power from non-blinking PSU. The system loses power, why?
Blinking green status LED is an indication that the power supply was not inserted all the way into the Power Distributor that caused the intermittent "Green" status light. To resolve the problem, re-seat the power supply and make sure it firmly inserts to the Power Distributor Unit.
