I spent a frantic ten minutes in the early hours of last night scrabbling around in the dark with wire cutters and a fading torch trying to patch in a LCD monitor and KVM switch to UPS power, the normal mains supply for them having previously failed due to a midnight team digging up the road outside. Happily I managed to do a proper shutdown of the protected servers before the UPS battery (and my torch) gave out.
If ye are ever enagaged in wiring up a server rack cabinet, can ye
a) Connect these low wattage items permanently to the UPS output, or... b) Put them on an obvious extension block and compatible inter-connector so they can be quickly unplugged and swapped from dead mains supply to UPS output?
I was pretty lucky to find random IEC leads and a spare 13A extension block in a cardboard box next to the rack. And a tool box...
Phew....
