Is there a method to test the internal batteries on a 9406-720 without
taking it off the UPS and running it via the internal batteries, or, do we
need to power down the UPS while the 720 is running and wait for it to crash
We need to do some failure testing on some systems that are connected to
UPS's but we are unsure of how healthy the UPS's are (they are Eton
Powerware 9325s, as specified by IBMs Econfig, and are 4 years old).
What we need to find out is should there be a power failure how long can
the 720 continue to run once the UPS battery has depleted. Obviously the UPS
are set to send the signal to the AS/400 to begin a PWRDWN IMMED as soon as
there is a power disruption.
Your thoughts, as always, are appreciated.
