> Buy a row of -48 batteries and a
-48 power source, your servers will stay up for hours.
That's only half of the solution. How will the phones be
powered? Some thoughts:
-If your power is iffy and you know it will go out,
install a positive interlock at the main breaker
panel for those breakers responsible for your servers. Then, get ye to the
home reno store and buy a 2kw generator. When the power goes out, the sequence
is like this:
Power goes out > UPS keeps up servers > You
start the generator > Interlock switches from mains to generator > UPS
"thinks" power is back
About $400 for the interlock and, say, $1200 for the
generator
-Midspan POE injector will keep up your phones if it
is UPS'ed as above. Some phones suck a lot of power. My 3Com midspan injector
is 200W with 24 ports, but I can only use 15 of those for my Mitel 5220's
before the injector shuts down. The 5220's take 14 W at a time!
$900 for the injector
-A small UPS for each phone would work, they are very
inexpensive these days and should keep a phone running for a few hours.
$29 at Costco X # of

-We have a disaster recovery plan with our telco
filed. When our T1 goes out, we call a certain number (by cell of course!) and
say: "Enable the plan" and they re route our DID's to cell numbers. This is a
software change on their end and it takes a few minutes. This will vary
by carrier, of course. Ours (Allstream / AT & T) are really good to work
with. The ILEC, Telus? Not so much.
