Supported EX Series switches
In Junos OS Release 19.3A2, the J-Web interface supports EX4650 switches as standalone switches, EX2300, EX2300-C, EX3400, EX4300, EX4300-MP, and EX4600 switches which are supported from earlier releases.
You cannot connect to and perform initial configuration of EX2200-24T-4G-DC and EX4600 switches by using the EZSetup procedure from the J-Web interface; you must use EZSetup from the switch console.
To obtain more information about the components that are supported on each switch, and the special compatibility guidelines for the release, see the Hardware Guide for the switch.
