This read-write DisplayString accepts a port specification (using shorthand formats like "1/2" or ranges like "1-3") and, per its source description, briefly drops PoE power on the named port(s) in order to force a power cycle of the attached device. Admins use this as a remote power-cycle command for locked-up PoE devices like IP cameras or phones, without needing physical access to unplug them. For example, writing "1/2,1/5" to this object would momentarily cut and restore PoE power on ports 1/2 and 1/5 to reboot whatever is plugged into them.
