-LEDs flashing: status change in progress.

-LEDs ON: the outlets are supplied with power.

Outlets 1 and 2 can be remotely programmed and controlled. They may be used for sequential start-up of the protected applications, shedding of non-priority applications during operation on battery power, and priority management at the end of battery backup time to reserve the longest possible backup time for the most sensitive applications. These outlets are programmed using Solution Pac software.
