5.0 Operation

■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.
