Chassis power supply LED indicators

Indicator Name	Color	Description
Status/AC/DC OK	Solid Green	Normal operation. The power supply is properly connected to the AC power source. It functions correctly and delivers DC power to the system.
Status/Failure	Solid Amber or Solid Red	Fault or Failure. The power supply has failed, is not providing DC power, or has a critical fault, such as over-temperature or a fan failure. The module typically needs to be replaced.
Status/AC/DC OK	Off	No power. The cause of no power is one of the following: the AC power cord is not connected, the power switch is off, or the power supply is completely dead.
Status/AC/DC OK	Blinking Green	Hot-swap ready/Pending. The power supply is in a standby state, waiting to be fully initialized. It might also be ready for removal or insertion (though this state is less common on all models).
