Looking at the documentation (linked below), it would appear the EX4650 has the exact same rack-mount kit as the EX4500 
and EX4600 do.

They all share the fundamental problem I'm taking about, namely that there are fixed mounting ears on the port side of 
the switch, which prevent removal through the cold aisle (assuming data centre/PSU-to-port airflow).

The "sliders" are really just there to prevent the PSU end of the switch to sag.
