Suggested Action
The utility voltage is frequently
outside the UPS operating range.
Update the configuration.
Contact a qualified electrician to
make sure that utility power is
suitable for the UPS.
Remove one or more devices to
reduce the power requirements.
Make sure that the devices are
not defective.
If the UPS is supplying battery
power, save current work and
shut down the system. Allow the
batteries to charge.
If the UPS is supplying utility
power, no user intervention is
required. Allow the batteries to
charge.
Allow batteries to charge for 24
hours, then initiate self-test. If
LED 10 is red, replace batteries.
Update the Shutdown Delay
from 5-seconds to 3-minutes.
Use Compaq Power
Management Software to specify
a suitable delay.
