PDU/UPS fun and games!?!?!
I was DCM for a Local Authority in the UK "There's Lovely".
We had bought a new UPS - but we think it was being overloaded and actually went 'pop' with a spark when in use.
Result - no power to the DC.
I call the manufacturers and they suggest that I put it into bypass mode...
this involved cutting the zip-tie on the middle power handle ("cut the red wire, not the blue wire" went through my head as I squatted with a pair of cutters).
I cut the tie and removed it and gave the bypass switch a ¼ turn
"*** BANG ***" - I leapt so high that I think I banged my head on the ceiling and poo-ed my pants (metaphorically - but it was close).
The UPS was fine - my "friends and colleagues" had arranged that my operator was standing behind me with a metal serving tray and a rubber mallet(!?), so that, at the moment of switchover, he whacked the tray.
Anyway, I only received 5 years "suspended" for justifiable homicide :-/
thanks for listening DPM/DCM/RCT
