  • 問題を分離するには、以下の手順を実行します。
    • コントローラポートのステータスを確認し、Tx 信号の 電力が少ない場合はSFPを交換します。
    • 接続されているスイッチポートのSFPステータスを確認し、スイッチポートのTx 電力が少ない場合はSFPを交換します。
    •  両方のFCエンド側でSFP Tx電力が正常で、 いずれかの側でSFP Rx電力が低い場合は、FCケーブルを交換します。
    • パッチパネルが関連している場合は、リンクコンポーネントのトラブルシューティングを行います。
    • 両端に低いRx信号がある場合は、 その間にパッチパネルがあるかどうかを確認し、テスト目的で別のポートを試してください。
