Abstract

A vertical-mount network remote power management outlet strip embodiment of the present invention comprises a long, thin outlet strip body with several independently controllable power outlet sockets distributed along its length. A power input cord is provided at one end, and this supplies AC-operating power to relays associated with each of the power outlet sockets. The relays are each addressably controlled by a microprocessor connected to an internal I2C-bus serial communications channel. The power-on status of each relay output to the power outlet sockets is sensed and communicated back on the internal I2C-bus. A device-networking communications processor with an embedded operating system translates messages, status, and controls between the internal I2C-bus and an Ethernet port, and other external networks.
