はじめに
一般的な機器では、ご利用環境(設置ラック環境等)によって筐体の温度が上昇しFanの回転速度が変化することがあります。本記事ではFPR1000/2100シリーズの筐体温度やFanの回転速度について確認する方法を紹介します。
* 動作確認にはFPR2110-ASA Software Version 9.12.3.7 、FPR1140-ASA Software Version 9.14.1.10 を使用しています。
確認方法
FXOS の CLI から下記コマンドを実施することで確認することができます。
なお、筐体やSoftware Version によって出力形式が異なる場合がありますので、下記出力例はあくまで参考に掲載しています。
- show stats
- コマンド実行時点のシャーシに関する詳細な統計情報を表示できます。

同様にFPR2130/2140 シリーズにて特定のFanの詳細情報を取得する際は、scope fan-module コマンドで推移後、show stats history fan-stats detail expand コマンドを実施します。
firepower-2130 /chassis # scope fan-module 1 1
firepower-2130 /chassis/fan-module # scope fan 1
firepower-2130 /chassis/fan-module/fan # show stats history fan-stats detail expand

トラブルシューティングでの利用
一例となりますが、Fan の回転が非常に速く障害の可能性を疑われた場合は、上記コマンドを取得いただき筐体温度やFanの回転数、Status が Operable となっているかをご確認下さい。もし筐体温度が高い場合は、ご利用環境の問題も考えられますため、空調環境の改善が必要となる可能性も考えられます。
また、ハードウェアの問題が検知された場合は show fault コマンドに詳細が出力されますので、合わせてご確認下さい。
