Abstract
A system and method is described that allows a PoE-capable switch to selectively provide power to one or more remote devices in an instance where power being supplied to the switch itself is limited or failing. In one embodiment, the switch receives a notification from an uninterruptable power supply (UPS) and, in response to receiving the notification, selectively provides power to one or more devices powered by the switch. Selectively providing power to one or more of the devices may include providing power to only a subset of the devices, providing a different amount of power to different ones of the devices, or providing power for different durations to different ones of the devices. In an alternate embodiment, in response to receiving the notification, the switch communicates with a remote device and causes the remote device to activate at least one power saving feature.
