Abstract: In a network including a controllable device, a method for sending a network management method to the controllable device including asserting a network management command directed to the controllable device and in response to the network management command generating and sending over the network a first number of WOL packets having a predetermined relationship to one another, followed by generating and sending over the network a second number of WOL packets, a predetermined relationship between the second number of WOL packets defining the network management command.

Abstract: An electronically controlled method of controlled enabling and disabling of ports, the method constituted of: receiving a message responsive to an access event, the message comprising an identifier of the accessing party and an indication of the access event; determining at least one power over Ethernet supplying port associated with the identifier of the accessing party; and enabling, in the event the indication of the access event is of entry, the determined at least one power over Ethernet supplying port associated with the identifier of the accessing party; and disabling, in the event the indication of the access event is of exit, the determined at least one power over Ethernet supplying port associated with the identifier of the accessing party.

Abstract: A method for communicating settable priority data from a powered device being powered over communication cabling to power sourcing equipment, the method comprising: prior to connecting power to operational circuitry of the powered device, transmitting first multi-bit data from the powered device to the power sourcing equipment; subsequent to the transmitted first multi-bit data, connecting power received over the communication cabling to the powered device operational circuitry; receiving information from the powered device operational circuitry; disconnecting the received power from the powered device operational circuitry; and subsequent to the disconnecting, and prior to reconnecting power to the operational circuitry, transmitting second multi-bit data from the powered device to the power sourcing equipment, the second multi-bit data being a function of the received information, at least one of the first multi-bit data and the second multi-bit data being a function of a settable priority.

Abstract: A system and method for power over Ethernet comprising: a plurality of power over Ethernet supplying ports; and a management station in communication with each of the plurality of power over Ethernet supplying ports, the management station being operative to: disable at least one first power over Ethernet supplying port of the plurality of power over Ethernet supplying ports on a predetermined scheduled basis. Preferably the management station is further operative to: receive an entry indication; and enable the disabled at least one first power over Ethernet supplying port responsive to the received entry indication.
