Output power
The UPS continuously monitors the power consumed by the load. The
value given is a percentage of the full load rating of the UPS. This informa-
tion may be logged using UPS monitoring software, plotted using a spread-
sheet application, and used to track load usage over extended periods.
Output voltage, internal temperature, battery voltage, battery capacity
The UPS continuously monitors the rms output voltage, internal tempera-
ture (°C), battery voltage, and the remaining battery capacity as a percent-
age of the fully charged condition. This information is valuable for
troubleshooting.
5.5.3 Power management
Shut down
While the UPS is operating on-battery, you may direct it to shut down after
a user-specified delay. Controlled shutdown of the UPS conserves battery
capacity and helps to extend battery life.
Shut down with delayed restart
You may direct the UPS to shut down in any mode following a user-
specified delay, and then restart after a user-specified interval. The restart
delay may be used to stagger the power-up of multiple network servers
protected by multiple UPSs.
Simulate power failure
You may direct the UPS to simulate a power failure by briefly operating
on-battery. This function is useful for test purposes.
Turn off
You may direct the UPS to turn off immediately, or after a user-specified
delay.
