So long story short they were installing a generator in the location where the server is which was running ESX 4.0. So I puttyed in, did a shutdown as I have done many times. Then turned off the UPS that it was connected to. 2 days later (now) I come back power up the UPS and the other things on the UPS come up switch, etc. nothing major. ML 350 nada not even power supply LEDs. Switched UPS outlets and even regular outlet nada. Changed wires nada. A quick search on google saids its bad power supplies which I find hard to believe as I just turned off the UPS no shock no anything aside from a quick blip right before I turned them off when the vendor started cutting out power a bit earlier then expected. Ideas!?
