The REPO feature shuts down the protected equipment immediately and does not follow the orderly shutdown procedure initiated by any power management software. Any devices that are operating on battery power are also shut down immediately. When the REPO switch is reset, the equipment will not return to utility or battery power until the UPS is manually restarted.
