ABSTRACT:
The method of management of the hot insertion of an electronic card (11) in a system (10) comprises the successive connection of the card to two supply potentials (U0, Ui) available in a connector (20) so as to obtain transient connection signals (41, 42) during the hot insertion of the card, the detection of the transient signals for providing a binary signal (Vi), one binary state (Vi=1) of which represents the hot insertion of the card, and the use of said state of the binary signal (Vi) for rendering the card operational in the system. The hot insertion detector (37) includes a bistable logic circuit fed during the connection of the card to said potentials and provided with biasing means adjustable depending on the presence or otherwise of the transient signals.
