RE: AS400 lost power

["Eric Graeb" <egraeb@xxxxxxxxxxxxxxxxxxx>]

Assuming all hardware in the room is on the same UPS and given the same
priority and there are no other limitations caused by extension cords, power
bars etc.  I'd say the UPS was set to communicate with the AS/400 it would
have told the AS/400 to start shut down procedures but the file servers
would remain running.  The other possibility is the power requirement for
the file servers was likely less then the AS/400.  There was enough power
left in the ups to sustain their power requirements but not enough for the
higher requirement of the AS/400.

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
