LEDの割り当てと表示パターン、使用例


LEDの割り当て (LED assignment)

Status LED

MA-X3xx には、2色(赤/緑) LED が 4 個 (POWER, STATUS-1〜3) 実装されています。
(English:MA-X3xx is equipped with four two-color (red/green) LEDs (POWER, STATUS-1 to 3).)


それぞれのデフォルトでの割り当ては下記のようになっています。
(The default assignments for each are as follows)

LED Color 状態 意味 sysfs以下 相対PATH
POWER 緑(green) 消灯 電源OFF(Power OFF) PowerLED:G
点灯 電源ON(Power ON)
赤(red) 消灯 power-stat:r
点灯
STATUS-1 緑(green) 消灯 system-status1:g
点灯
赤(red) 消灯 system-status1:r
ハートビート Kernel動作中(Kernel is running)
STATUS-2 緑(green) 消灯 system-status2:g
点灯
赤(red) 消灯 system-status2:r
点灯
STATUS-3 緑(green) 消灯 system-status3:g
点灯 出荷状態での起動(Default startup)1)
赤(red) 消灯 system-status3:r
点灯
点滅(flashing) シャットダウン処理中(shutdown process in progress)


全ての LED は LED class driver2) での実装となっていますので、 sysfs3) I/F により任意の動作に変更が可能です。
(All LEDs are implemented with LED class driver2) , so they can be changed to any operation by sysfs3) I/F.)
