摘要： A PCI Express switch which connects a plurality of peripheral devices to an arbitrary one of a plurality of CPUs through an Ethernet is constituted by a plurality of upstream and downstream PCI Express-network bridges, an Ethernet switch, and a system manager. Each of the upstream and downstream PCI Express-network bridges includes a PCI Express adapter which terminates a link of a PCI Express bus, a network adapter which terminates a link to the Ethernet switch, and a control unit which encapsulates a TLP in a frame, the destination of which is a MAC address of a bridge to which the destination is connected to transmit and receive the frame. Because the switch according to the present invention comprising a plurality of upstream PCI Express-network bridges and a plurality of downstream PCI Express-network bridges connected to the plurality of upstream PCI Express network bridges through a network is equivalent to a conventional PCI Express switch, it is needless to change a conventional PCI software.

摘要： A detecting unit detects a connection of an external device to a connection port and stores the connection in a bridge state storage unit. This setting is autonomously completed by a device before an initial configuration is started by a host. A data transfer unit receives initial configuration data of a link-connection bridge from the host. Data is transferred to the linked-uplink-connection bridge with reference to the bridge state storage unit, data to a bridge which is not linked up is wasted, or an Unsupported Request is returned to the host to represent the absence of the link-connection bridge.

摘要： A communication equipment notifies a server equipment of a communication port to which a communication cable is connected. If another communication port as a connection partner of the notified communication port is not yet connected to the communication cable, the server equipment transmits a first notification instruction to another communication equipment having the said another communication port. The said another communication equipment indicates, in a viewable manner, a communication port corresponding to the first notification instruction as a communication port to which the communication cable is required to be connected.
