Compaq 204451-002 - UPS T2200 XR Reference Manual page 40

The following items should be carefully considered before utilizing Shutdown
Timing:
I
The length of battery protection increases as the load on the UPS
decreases.
I
After a power outage recovery, another outage could occur before the
UPS batteries fully charge. For a more robust system fault tolerance, set
the Countdown Time to a value small enough to allow battery reserve
for at least two shutdowns.
I
Do not allow the UPS to shut off until all applications are terminated
and all files in the system are closed. Set the Shutdown Delay to a value
large enough to ensure that the software has time to shut down a
worst-case computer environment.
I
If a system shutdown is necessary, the Compaq Power Management
software saves only named files. To avoid loss if a power failure occurs,
name any new files when they are opened.
