I was looking at the wrong power - that was the 230 that feeds the =
lamps.
FFS power is at the back of that same rack, 120V plugged into a UPS =
outlet above the manual mirror support air valves.  We found this =
morning that the wire had caught on something on top of the pier and =
been broken.  Should be up and running again soon, James is splicing it =
and we'll get it securely tied off after that.
