a.
Enter the On Battery values. When a utility power failure occurs, the UPS automatically switches to
battery power. One or all of the values in this column are set to allow protected servers to be
powered by a UPS operating on battery power. In the event of a utility power failure, all On Battery
settings are evaluated, and the first trigger that is reached initiates the shutdown sequence.
i.
In the Shutdown initiated if remaining backup time under field (entire UPS), enter the minimum
amount of battery life that can remain before the UPS shutdown sequence starts (0 to 99999
seconds, 180 seconds by default). The UPS Network Module initiates a UPS shutdown when the
remaining battery life reaches the specified time.

In the Shutdown initiated after field (individual load segments), enter the number of seconds after
the power fails that the UPS Network Module should wait before starting to shut down the load
segment (0 to 99999 seconds, 300 seconds by default). Enter a shorter delay for load segments
that power less critical equipment to preserve UPS battery power for other load segments.
In a redundant configuration, do not set the Shutdown initiated after values for both HP Network
Modules to the same time. Set the delay one minute apart so that HP Power Protector can
perform a graceful shutdown.
IMPORTANT: The Shutdown initiated after value entered for the UPS Network Module must be
equal to or greater than the HPPP Client configured with the longest Shutdown initiated after time.
