Abstract: PROBLEM TO BE SOLVED: To provide a simple enclosure service using a high speed point-to point serial bus. SOLUTION: An enclosure service in a computer system comprising a host computer and at least one target device is supplied on a functional path, favorably a comparatively high-speed point-to-point serial bus between the host computer and at least one target device. At least one target device and the host computer respectively have a full power operation mode and an auxiliary power mode. The host computer generates the enclosure service command and transmits it, on the functional path, to at least one target device. At least one target device, even in the auxiliary power mode, can receive the enclosure service command and respond to it.
