Thanks for the info, everybody. Switch and surge protection arrived, are
installed, and UPS is on its way. -Gary

The UPS does give more protection. The power to the switch is always
consistent. Brown-outs occur when something huge gets turned on in a
building. There is a large power draw, and it takes the power grid a little
bit to recover. That drop in voltage is not good for any computer
equipment, but most stuff can handle it. A surge protector will not help,
but a UPS will. Also, power spikes can sometimes screw up network data, but
aren't usually enough to trip a surge protector. You may see screwy things
on that network and spend hours trying to troubleshoot them when it's just a
power issue. I like the peace of mind that comes from knowing the equipment
is running exactly as it is specified.

Nancy and Paul,
If you need to protect from power fluctions only and don't care if the the
equipment goes out during power failure, get a surge supressor. If you need
continuity as well as power protection, get a UPS. Is it that basic? Or is
it more complicated than that? Does a UPS give more protection, due to the
battery buffering the power fluctuations?

Gary,
I have some small APC and Tripp Lite UPS. They both work fine and I can
still get batteries for some older units. In a nut shell a UPS works
something like this. The batteries soak up the electricty and outputs a
consistant level to the equipment, during surges or brown outs.
Different models come with different number of power plugs for the equipment
and can handle different amount of VA. How long they will run your equipment
during a power outage, depends on the battery size. You just need to size
one to your needs.
Hope this helps.
Nancy

OK. I've looked around on the web. Prices go anywhere from $29.95 to a
couple hundred dollars for UPS's. Anyone have an opinion about which one to
buy - or not to buy? Does the price reflect the quality? Thanks for any
input. -Gary

I would definitely add a UPS. Look at your power requirements for the new
switch. A 500VA UPS should be more than enough and I only paid $80 for the
last one I bought (haven't checked prices in a while). $80 sounds like a
pretty cheap security blanket to me. Why take a chance?
Thanks,
Gary

All my high end switches are powered from UPS'es. Usually a decent UPS
comes with a replacement warranty if they inadvertently let a surge through
and smoke some stuff connected to them. I know you didn't use a wall outlet
to power your switch right? ;)
In case you didn't, this would be an excellent opportunity to start building
that screaming network with 3Com Gigabit Ethernet managed rackmountable
switches you had been drooling over....

Replace the switch and save yourself the trouble down the road. Even
if it does work or you can get it to work other componets have been
