A rack with a mounting bay to accommodate servers, wherein 1) the mounting bay defines two opposing internal areas disposed parallel to an insertion direction of the servers and divided into a multiplicity of slots, 2) one or more data lines for data connection of servers are configured in the rack, 3) the data lines include optical data lines, and 4) on at least one of the two internal areas of the mounting bay, an end section of a data line with a data interface is disposed on each slot such that a contactless optical data connection to a further data interface on a corresponding server is enabled.

Rack, server and assembly comprising such a rack and at least one server

An electronic device (), which can assume an operating state and at least one energy-saving state, with a power supply () that can be connected to a mains voltage, and an evaluation unit (), which can control the electronic device () from the operating state into the energy-saving state and vice versa, wherein the evaluation unit () is connected to the power supply () in such a way that the power supply () can be turned off by the evaluation unit () for assuming the energy-saving state and can be turned on again for assuming the operating state, and the evaluation unit () can be supplied, at least in the turned-off state of the power supply (), with energy from another electronic device, which is connected via a standard interface to the electronic device, and/or with energy from a capacitor and/or with energy from an accumulator and/or with energy from a solar cell. The invention also relates to the method for controlling the electronic device in at least one energy-saving state and also to a computer and also to an arrangement made from a computer and the electronic device.
