SRX4120 Chassis LEDs

This topic describes the status LEDs for the chassis and ports on the SRX4120.

The LEDs on the SRX4120 indicate the status of the device and its components. You can also use the LEDs for troubleshooting.

Chassis Status LEDs

You can find the chassis status LEDs on the front panel of the SRX4120.
