RE: Power Handling programs and QPWRRSTIPL

I have calculated the duration of the ups batteries and start a controlled
powerdown 1/2 life of the batteries.  This save the ups batters to handle
situtations such as you stated.

Subject: Power Handling programs and QPWRRSTIPL


I'm writing a power handling program to better control the shutdown of
our system when the power dies and were running on UPS batteries.  I'm a
little concerned about setting QPWRRSTIPL = 1 (which auto-IPL's the
system once power is restored).  My concern revolves around the
following scenario.  

My UPS batteries get fully discharged during a power outage.  Utility
power then gets restored and an IPL is started automatically.  5 or 10
minutes into the IPL, power drops once again and, since my UPS batteries
were just fully discharged, they are of no use and the 400 goes down in
the middle of an IPL.

To me, that seems a rather dangerous possibility.  Am I overstating the
risk or is it an acceptable one.  My initial reaction is for me to set
up pager software to send an operator a message to come in and manually
re-start the system when it comes back up??


Any Thoughts??
