Upon reset, the value defaults to the maximum value of 99999 seconds. • The Operating system shutdown time value entered for the HPPP Administrator must be equal to or greater than the HPPP Client configured with the greatest operating system shutdown time. • After the operating system shutdown begins, the shutdown process cannot be canceled, even if utility power is restored. • For load shedding, each Client shuts down based on the delay settings for that Client. This increases the backup time for the remaining Clients. • The UPS powers down after all load segments power down. • If any other condition happens during the initiated shutdown, such as the battery capacity is under limit, the HPPP Administrator sends a shutdown command to all Clients to start the shutdown process earlier.

Configuration and operation 62
Upon reset, the value defaults to the maximum value of 99999 seconds.
•
The Operating system shutdown time value entered for the HPPP Administrator must be equal to or
greater than the HPPP Client configured with the greatest operating system shutdown time.
•
After the operating system shutdown begins, the shutdown process cannot be canceled, even if utility
power is restored.
•
For load shedding, each Client shuts down based on the delay settings for that Client. This increases the
backup time for the remaining Clients.
•
The UPS powers down after all load segments power down.
•
If any other condition happens during the initiated shutdown, such as the battery capacity is under limit,
the HPPP Administrator sends a shutdown command to all Clients to start the shutdown process earlier.
The following example shows the shutdown parameters for a UPS with two load segments, one connected
server that has HPPP Administrator installed, and three connected servers that have HPPP Clients installed on
each server.
