Appendix A—Glossary Explanation
Agent—Agent is a background application of the Windows/Unix/Linux operating system.
UPS Battery Low—When utility power fails and the battery supplies power, if the battery
voltage is lower than a certain value (refer to UPS Specification), the
UPS will send a audible alarm at 1 second intervals.
UPS battery backup time exhausted—Indicates when the UPS AC fails, the battery
supply time has exceeded the “battery backup time” that has been set
(“Battery backup time” can be set in the “Shutdown parameter” screen
of HP Value UPS Manager).
UPS output overload—UPS load is more than 100% rated load.
Load too high—UPS load is more than 100%～110% rated load.
Supply power in Bypass mode—For the reason of the UPS not on or the hardware
fault, the input will not pass the inverter of the UPS, but output directly.
At this moment, if AC fails, the UPS will not startup backup battery, so
the output will also out of electricity.
UPS self-test—After UPS supply mode is switched from utility power mode to battery
mode and work on for a period of time, return to utility power mode again.
The purpose of self test: First, is to check if it can supply normally in
battery mode; second, is to make the battery discharge once, which is
helpful for the battery maintenance and can prolong the battery’s service
life.
Self-test failure—Indicates that it is found out that it is not able to supply power normally
in battery mode via self-test .
Battery Backup Time—The time that the battery supplies power when utility power fails.
After this time has expired, the Agent begins to shutdown any open
applications.
Shutdown File Max Execution Time—The time to close any running applications before
system shutdown.
System Shutdown Need Time—The time for system shutdown, and it is also the time
from system startup until the UPS powers down..
Remote Shutdown by Agent—local Agent will shutdown in shutdown delayed time
after the specified Agent shutdown.
Start Warning before Scheduled Shutdown—If the user has set a time for shutdown, HP
Value UPS Manager will begin warning at this time before a
scheduled shutdown.
