Abstract

L'invention concerne un procédé et un appareil de gestion d'une carte principale et d'une carte de sauvegarde, ledit procédé consistant : à détecter un signal de remplacement à chaud entre la carte de circuit principale et la carte de sauvegarde ; à effectuer un processus de filtrage sur le signal de remplacement à chaud ; à déterminer si un niveau du signal de remplacement à chaud a changé après le processus de filtrage ; si le niveau du signal de remplacement à chaud a changé après le processus de filtrage, à commander la carte principale et la carte de sauvegarde afin que celles-ci n'émettent pas de signal de commande interactive.
