[Discuss] APC Back-UPS ES 350

I recently got a couple of UPS devices from a company leaving the Regus
office. I'm pretty sure at least one of the  batteries is good. Since we
have had a very stable power situation at home, I have never needed a
UPS.. There are several advantage of a UPS  over just a battery backup.
The question I have since I don't have the CD that came with it is its
usability under Linux. Certainly from a pure electrical standpoint, it
would keep my systems up for a short time, but most UPS systems come
with software that can be configured to shut the system down gracefully
in the event of a power failure. Recently, as a result of Irene we had a
few short power outages, and last year we had a truck pull down the
cables on our street. I haven't checked online to see if there is
support for UPS on Linux.

The second question is operating cost. I recall a few years (15) ago at
a BCS event, one group would pop the breakers when they plugged in their
UPS, yet their systems worked fine with no UPS. I know the UPS will draw
some current even if it has nothing plugged into it.

The third question is that there are 3 backed up sockets, but I want to
plug in the router, cable modem, monitor and computer. Is there any
issue connecting a couple of low power devices with an extension cord.
