Starng in Junos OS Release 20.1R1, you can use the request chassis beacon command on EX4300-48MP
switches to idenfy the switch or a port on the switch. When you execute the command, the status
LEDs on the RJ-45 network ports blink two mes per second irrespecve of the mode the ports are
operang in (see How to Locate a Device or Port Using the Chassis Beacon).
Table 26 on page 82 describes the Status LED on the ports on the 4-port 1-Gigabit Ethernet SFP/10-
Gigabit Ethernet SFP+ uplink module for EX4300-48MP and EX4300-48MP-S switches.
