Abstract

L'invention concerne un procédé de détection de défaut d'insertion pour un dispositif externe, ainsi qu'un dispositif informatique, ayant trait au domaine technique des serveurs, destinés à assurer la connexion correcte entre une station d'accueil et un dispositif informatique, de sorte que le dispositif informatique puisse utiliser normalement un dispositif matériel à étendre qui est inséré dans la station d'accueil. Le dispositif informatique comprend un contrôleur, une pluralité de connecteurs d'adaptateur et au moins deux stations d'accueil; chaque station d'accueil comprend au moins deux connecteurs d'extension; l'un des connecteurs d'adaptateur est connecté à un connecteur d'extension; la pluralité de connecteurs d'adaptateur sont connectés séparément au contrôleur; et le contrôleur est configuré pour : déterminer la relation de connexion en cours de chaque station d'accueil, la relation de connexion comprenant une relation de connexion entre chaque connecteur d'extension de la station d'accueil et le connecteur d'adaptateur correspondant; et émettre des informations d'alarme lorsque la relation de connexion en cours de la station d'accueil est différente d'une relation de connexion prédéfinie de ladite station, les informations d'alarme servant à indiquer que la relation de connexion en cours de la station d'accueil est incorrecte.
