  • Power over ethernet battery backup
    Patent number: 7498692
    Abstract: An apparatus, system, and method for providing DC battery backup power to Power over Ethernet, (PoE) Mid Span or End Point Power Sourcing Equipment, (PSE), such that in the event of the loss of utility power the PSE device is able to continue to provide power for some time while battery capacity remains. The apparatus includes an AC to DC converter that receives an AC power input and outputs DC power to the power over Ethernet circuitry and a DC battery pack that provides backup DC power to the power over Ethernet circuitry.
