[0050] CPU50はステップ S38で CPU周辺制御部 48及び PCIバス 44を介して障害発生 のポートのインタフェース回路 42からポート接続状態を含む詳細情報を取得する。そ して、 CPU50はステップ S39で取得したポート接続状態を含む詳細情報を CPU周 辺制御部 48経由でコンソール端末 34に送信する。これにより、ポート接続状態を含 む詳細情報がコンソール端末 34に表示される。 In step S38, the CPU 50 acquires detailed information including the port connection status from the interface circuit 42 of the failed port via the CPU peripheral control unit 48 and the PCI bus 44. Then, the CPU 50 transmits detailed information including the port connection status acquired in step S39 to the console terminal 34 via the CPU peripheral control unit 48. This includes the port connection status. Detailed information is displayed on the console terminal 34.
[0051] 本実施形態では障害が発生したポートを、ダイヤルスィッチを回転させて選択し確 定スィッチを押下して確定することで、コンソール端末 72に障害ポートの状態が表示 され、ポートのポート番号やラインセット番号の目視確認やキーボード操作が不要に なり、障害発生のポートの特定及び情報取得時間を短縮でき、修復作業に着手する ことが可能となり、管理者の作業効率の向上が可能となる。  [0051] In the present embodiment, the failure port status is displayed on the console terminal 72 by selecting the failed port by rotating the dial switch and confirming by pressing the confirm switch, and the port number of the port In addition, visual confirmation of line set numbers and keyboard operation are no longer necessary, and it is possible to identify the port where the failure occurred and shorten the time to acquire information, and to start repair work, improving the work efficiency of the administrator. .
[0052] なお、上記実施形態では、ネットワークインタフェースとしてモジュラ一式コネクタ RJ 45を用いて!/、るが、ネットワークインタフェースは光ファイバのコネクタであっても良!ヽ  In the above embodiment, the modular connector RJ 45 is used as a network interface! /, But the network interface may be an optical fiber connector.
[0053] なお、 LED39a, 68a, 68b, 78が請求項記載の接続状態表示手段に対応し、スィ ツチ 39b,インタフェース回路 69,ダイヤルスィッチ 73,確定スィッチ 74が特定手段 に対応し、コンソール端末 34, 64, 72, CPU周辺制御部 48, CPU50が詳細情報 表示手段に対応する。 [0053] The LEDs 39a, 68a, 68b, 78 correspond to the connection state display means described in the claims, the switch 39b, the interface circuit 69, the dial switch 73, and the confirmation switch 74 correspond to the specifying means, and the console terminal 34 , 64, 72, CPU peripheral control unit 48, CPU50 correspond to detailed information display means.
