I'm guessing you meant UPS, anyway, a UPS wont protect you from human
error.
Also, most buildings, at least in this country, have a fire emergency
shutoff requirement, meaning mains is isolated from the building, and
the back up gennies are also forbidden to be engaged - UPS's dont last
forever.
Guys, please don't argue on kindergarten level. The UPS is for backing
a
sudden death, but not for running five days. Of course you can do a
controlled
shutdown if battery level falls below a trigger value. And this is
about all
you need: control. There is no fs error as long as you perform a
regular
and you've never seen these cause problems with FS? then you must be a
newbie, in over 25 years I've seen it happen several times - yes even
after an apparent controlled shutdown.
shutdown. If UPS-backup is forbidden in your country then I suggest
moving to
civilized regions of the planet ;-)
Now whos on kindergarten level, do you really want fireman pouring water
on fire on a level of a building thats powered up because some lamer has
a generator running? really? I'm sure those firemen would gladly hand
YOU the hose, the best UPS systems runtime we've seen under average load
for a large ISP data centre is 21 mins, usually ample time to allow the
generators to start up, come to full power, and switch in taking over
the load, but thats not going to help during a building fire, once their
depleted, their depleted.
