Abstract
UNA UNIDAD DE CONTROL ES DESCRITA, QUE INCLUYA UNA UNIDAD DE PROCESO (12) CONTROLADA POR UN PROCESADOR DE SERVICIO (14), Y UNA PLURALIDAD DE ADAPTADORES (18) QUE CAMBIAN DATOS Y / O SEÑALES DE CONTROL CON DICHA UNIDAD DE PROCESO (PU). PARA ASEGURAR UNA OPERACION CONTINUA DE LA UNIDAD DE CONTROL, LOS ADAPTADORES ESTAN COLOCADOS DENTRO DE AL MENOS DOS GRUPOS (56, 58) Y EL PU ESTA COLOCADO DENTRO DE AL MENOS DOS PARTES (26, 28), CADA GRUPO DE ADAPTADORES SE CONECTA A UNA PARTE DEL PU DEDICADO POR UN BUS PRIMARIO (52, 54). ADEMAS, EN ORDEN PARA PERMITIR LA RETIRADA DE UN GRUPO DE ADAPTADORES HACIA OTRA PARTE DEL PU SI LA PARTE DEL PU A LA CUAL ES NORMALMENTE CONECTADA ESTA INOPERATIVA, UN DISPOSITIVO INTERRUPTOR BUS (30) ES PROVISTO. ESTE DISPOSITIVO INCLUYE AL MENOS DOS PARTES INTERRUPTOR (38, 40) Y CADA UNA REPRESENTA LA INTERRUPCION DE UN GRUPO DADO DE ADAPTADORES HACIA UNA PARTE DEL PU DADA, ACORDE AL ESTADO DE CADA PARTE DEL PU. POR LO TANTO, CADA PARTE DEL INTERRUPTOR ES CONECTADA A UN GRUPO DADO DE ADAPTADORES POR UN BUS PRIMARIO (52, 54) Y A LOS OTROS GRUPOS DE ADAPTADORES POR BUSES SECUNDARIOS (46, 48) QUE LLEGA A SER ACTIVO EN MODO RETIRADA.
