Re: AS400 lost power

We have a sizable UPS.  As part of routine maintenance the service company 
checks the batteries.  Here's the catch.  Your warranty probably will 
replace a battery if it goes bad.  However, that's small consolation after 
you've just lost power.  Now, when they test, and some are getting weak, 
we've been known to replace them all.  (Got 4 trolling motor batteries 
this way.)  The service company normally charges us for the batteries when 
we do it this way.  A little costly, but at least the UPS stays up when 
you expect it to.

Then again, maybe your UPS is undersized for your environment?

Theory is that our UPS is only supposed to last long enough until the 
generator automatically kicks on.  Now when someone accidentally flipped 
the breaker between power source and UPS we lost the machine room.  But 
the UPS did last 45 minutes.  Running two 270's, i5-520, i5-570 (with 3 
total racks), 4 racks of pc's, 3 racks of misc cabling equipment (like 
routers, switches, modems, etc), and 4 terminals.

AS400 lost power







Why, why, why.....

Our data center lost power and the AS400 went down hard but the file 
servers in
the same room stayed up.  The room is on a UPS but the batteries were so 
weak
that it didn't really matter. 

Why would this happen?

(BTW, batteries are now replaced and UPS works).

TIA,


Jerry
