Abstract
A system and method for supplying uninterruptible power has active power negotiation and an extended range. The system includes a housing, a power supply input, a power source equipment input, a powered device output, an alternative power supply, and a control module. The control module includes a comparator, a switch, a converter, and an injector. The injector includes a regulator and power autonegotiation module. The injector actively manages the power to the powered device, even when the PoE available from older power source equipment differs from the PoE requirements of an updated powered device. There can also be an Ethernet switch as a power source equipment extension between the powered device and the system. The Ethernet switch extends the range of the powered device from the system.
