Abstract

The invention is related to hot plugging of an electrical circuit (1) into a separate non-quiesced signal net (6) in an active system (7), such as a digital or analog bus. The inventive solution proposes the addition of a preconditioning network (4) to precondition the electrical circuit (1) to be hot plugged by partially precharging the parasitic input capacitances (C.sub.c, C.sub.e, C.sub.m) of the electrical circuit (1) before hot plugging. The precharging of the parasitic input capacitances serves to minimize transient effects on the active system (7).
