Table 1: AC Power Supply LEDs on a QFX3500, QFX3600, or QFX3600-I Device
LED | Color | State | Description |
|---|---|---|---|
AC OK | Unlit | Off | The power supply is disconnected from power, or power is not coming into the power supply. |
Green | On steadily | Power is coming into the power supply. | |
DC OK | Unlit | Off | The power supply is disconnected from power, or the power supply is not sending out power correctly. |
Green | On steadily | The power supply is sending out power correctly. | |
Fault | Amber | On steadily | An error has been detected in the power supply. Replace the power supply as soon as possible. To maintain proper airflow through the chassis, leave the power supply installed in the chassis until you are ready to replace it. |
If the AC OK LED and the DC OK LED are unlit, either the AC power cord is not installed
properly or the power supply fuse has failed. If the AC
OK LED is lit and the DC OK LED is
unlit, the AC power supply is installed properly, but the power supply
has an internal failure.
