My big APC UPS has tripped twice now.
We have the builders in. They've patched in the two circuits that the servers use, and the power is flowing through. Though they're still working on the distribution board.
The UPS won't power on with all devices attached. No problem... switch a few off and it comes up. Very noisily though.
I don't know if this is a sign of the UPS being on it's last legs or something dicky with the power feed.
Anybody have any experience of this??
