An SOI connection for connecting sourcedrain regions of one transistor to sourcedrain regions of another transistor without the use of overlying metal. The method further includes receiving commands sent to the server regularly and assigning a first predetermined value to the software MUX when the received command is not an Intelligent platform management interface command. The closed-loop control device is configured such that it bridges or turns off at least one of the pump stages on the basis of the conditions that are to be taken into account.
