Is the EX-SFP-1GE-T supported on the EX-UM-4X4SFP? We might need some extra copper ports on the EX4300. The configurator only list SX and LX SFPs as options.
These appear to be supported. You can find the full list of supported optics here: EX4300 Optical Interfaces
The table list only the EX4300-32F.
32-port EX4300 switches—Junos OS for EX Series switches, Release 13.2X51-D15 or later".
I would like to use it in the EX4300-48P as 49th and 50th copper port.
