A method of powering on a plurality of devices includes identifying a plurality of power distribution units disposed in a rack, wherein each power distribution units is connected to receive power from a main power source, and wherein each power distribution unit includes a circuit breaker. The method further includes identifying a plurality of devices disposed in the rack, wherein each device is connected to receive power from one of the power distribution units, and wherein the plurality of devices are selected from server nodes, network switches and external data storage devices. For each of the power distribution units, the plurality of devices that are connected to the power distribution unit are powered on in a sequence to prevent an inrush current from tripping the circuit breaker within the power distribution unit. The sequence powers on the devices identified as network switches and external data storage devices prior to powering on the devices identified as server nodes.

An information terminal apparatus includes a flat plate-shaped conductive housing including a first principal surface, a second principal surface, and a side surface that connects the principal surfaces, and a display provided on the first principal surface. The conductive housing includes a slit extending from the first principal surface to the second principal surface. Near the slit, a power feeding coil coupled to an IC element for an HF-band RFID system is disposed. The power feeding coil is magnetically coupled to the conductive housing via the slit. Thus, the conductive housing is utilized as a radiation element of the HF-band RFID system.

A power-over-Ethernet (PoE) apparatus is provided with PSE controllers that are cooperable to manage a global power budget of the PoE apparatus automatically. Information indicative of the global power budget is conveyed to a group of PSE controllers. The PSE controllers cooperate collectively to allocate the global power budget among themselves automatically and autonomously. This is accomplished in simple fashion without using a separate, programmed microcontroller. Each PSE controller also manages its own local power budget, allocating available local power among its own power sourcing ports.
