IT SupportOur IT support guy has been in the job since 1979, and never misses an opportunity to pick up a mouse and say "Hello computer" into it, Star Trek-style. Tell us your tales from the IT support cupboard, either from within or without.

That's where Serial comes into its ownThe UPS (at least IMHO w/ROV control desks) just sends out a telegram saying "Bugger me, the mains has gone! Turn off!" and the software on the PCs picks it up.
So if you've got multiple PCs hooked up to the same UPS you can split the RS232 Rx signal off to the different machines (either using a Y-adaptor (which cause more trouble than they're worth...) or a few MAX232 ICs).
With USB there's a whole load of other messing about.
Ethernet's probably the best option, though. Or having a set-up where you've got the intended number of servers coming off the UPS. What were you thinking having multiple servers on a single UPS that can't shut even one of them down automatically?!
