Network Appliance with Power Conditioning
First Claim
1. A network appliance apparatus to convey communication signals over a communication network to other nodes thereof in accordance with a network protocol, the network node appliance receiving electrical power from an alternating current (AC) electrical power source, the network node appliance comprising:
- a communication circuit to perform network communication operations on the communication signals in accordance with the network protocol;
a power conditioning circuit to produce conditioned electrical power from the received electrical power;
a power monitor and control circuit electrically coupled to the power conditioning circuit to analyze the conditioned electrical power against established power criteria and to generate a switch control signal in a signal state corresponding to each of a plurality of events that occur when the respective power criteria are met;
a switch circuit electrically interposed between the power conditioning circuit and the communication circuit to selectively provide the conditioned electrical power to the communication circuit in accordance with the state of the switch control signal; and
a housing enclosing the communication circuit, the power conditioning circuit, the power monitor and control circuit and the switch circuit and having disposed thereon electrical and communication port connectors through which the electrical power and the communication signals are provided to the power conditioning circuit and the communication circuit, respectively.

Abstract
A network appliance apparatus conveys communication signals over a communication network and is constructed from a communication circuit and a power conditioning circuit in a common housing. The power conditioning circuit conditions alternating current (AC) electrical power and it is determined which power criteria are met by the conditioned electrical power. The conditioned electrical power is selectively provided to the communication circuit in response to one of the power criteria being met such that the conditioned electrical power is removed from the communication circuit when another of the power criteria is met.

20. A tangible, non-transitory computer-readable medium having encoded thereon processor instructions that, when executed by a processor in a network appliance apparatus that conveys communication signals over a communication network by a communication circuit contained in a housing, configures the processor to perform:
-
determining within the housing which of established power criteria are met by conditioned electrical power produced by a power conditioning circuit within the housing from alternating current (AC) electrical power received through an electrical port connector in the housing; and selectively providing within the housing the conditioned electrical power to the communication circuit in response to one of the power criteria being met such that the conditioned electrical power is removed from the communication circuit when another of the power criteria is met.
