Abstract

L'invention porte sur un procédé et un appareil pour supporter une entrée de multiples terminaux d'interface série. Le procédé comprend les étapes suivantes : lorsqu'un terminal d'interface série initie une demande d'entrée, la demande d'entrée est transmise à un panneau de commande principal d'un châssis dans lequel un Contrôleur de Système (SC) principal est situé; le panneau de commande principal du châssis dans lequel le SC est situé détermine si le terminal d'interface série qui initie la demande d'entrée est ou non autorisé à entrer, et notifie le résultat d'entrée au terminal d'interface série qui initie la demande d'entrée. Par conséquent, grâce à la présente invention, lorsqu'il n'y a pas de terminal d'interface série dans l'état d'entrée et/ou lorsque le terminal d'interface série qui initie la demande d'entrée appartient au châssis dans lequel est situé le SC principal, le terminal d'interface série qui initie la demande d'entrée est autorisé à entrer afin de permettre à tout terminal d'interface série de demander une entrée, permettant ainsi de mettre en œuvre l'entrée flexible pour le terminal d'interface série et d'être propice à une maintenance de dispositif.
