To configure the shutdown parameters: 1. Configure shut down and restart: 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 (120 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 (120 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. The value you enter is continually compared with the maximum Shutdown initiated after shutdown time of all subscribed HPPP Clients. The highest value is automatically used. If the Shutdown initiated after (sec) field is set to none, UPS devices power down as late as possible without performing a graceful shutdown. HP UPS Network Module web interface 36
