1. A power supply comprising:
- a chargeable battery based secondary power supply;
an alternating current input interface for receiving an alternating current signal;
a power supply module that is operative to;
convert the alternating current signal into a direct current signal;
provide the converted direct current power to at least one power over Ethernet port;
monitor the alternating current input interface to identify an interruption in an alternating current signal;
test the chargeable battery based secondary power supply to ensure that it is operating correctly; and
switch the power provided to the at least one power over Ethernet port from the converted direct current power signal to the chargeable battery based secondary power supply.

Abstract
A multi-functional power supply that is advantageously suitable for distributed networking environments, such as the deployment of wireless networks. The power supply provides PoE ports for powering various devices and includes redundancy, back-up support, failover detection and monitoring/reporting. Thus, the power supply is particular well suited for a router or switch type environment that enables powered devices to be located in strategic locations without being limited by the provision of AC power outlets.

20. A power supply system that can be incorporated into a network based device and used to power one or more PoE ports, the power supply system comprising:
-
a chargeable battery; a plurality of PoE ports; an alternating current input interface for receiving an alternating current signal; a power supply module operative to; monitor the alternating current input interface to identify an interruption in an alternating current signal; convert the alternating current signal into a direct current signal; provide the converted direct current power to at least one PoE port; test the chargeable battery to ensure that it can handle a load; switch the power provided to the one or more PoE ports from the converted direct current power signal to the chargeable battery if a disruption in the alternating current signal is detected; a failover communication interface enabling the power supply to be communicatively coupled with at least one backup power supply operating in an off-line mode; and a failover module operative to; detect a failure in the power supply unit; request a backup power supply to change to an on-line mode for providing power to devices current attached to the PoE ports of the power supply system; and switching the power supply unit to an off-line mode after receiving a response from the backup power supply indicating that the backup power supply can change to an on-line mode; and a monitor module that enables the power supply unit to be monitored and controlled over an interface to an external device.
