Starting in Junos OS Release 20.1R1, you can use the request chassis beacon command on EX4300-48MP
switches to identify the switch or a port on the switch. When you execute the command, the status LEDs
on the RJ-45 network ports blink two times per second irrespective of the mode the ports are operating
in (see How to Locate a Device or Port Using the Chassis Beacon).
