Patent ID: 10129038

Abstract:
Disclosed is a system apparatus and device for facilitating the backup of network edge devices and methods of operation thereof. A monitoring circuit(s) may detect inoperable electrical power condition(s) (IEPC) on the power-line of a network edge device. Upon detection of an IEPC a backup power source may provide electrical power to the edge device. Upon detection of a connectivity fault between the edge device and its packet sink, a packet sink emulator may emulate a packet sink of the edge device. The disclosed system apparatus and device may implement a Power over Ethernet (PoE) power backup device for providing power to one or more edge devices, the device comprising: a PoE input port, an auxiliary power input port, a PoE output port, a power storage circuits, and power management circuits for detecting available power, switching between power sources, and regulate the power switching based on power detection outputs.
