10. Attach the rear mounting-blades to the rear post by using the appropriate screws for
your rack. Tighten the screws.
11. Ensure that the switch chassis is level by verifying that all the screws on the front of
the rack are aligned with the screws at the back of the rack.

Mounting an EX3300 Switch in a Recessed Position in a Rack or Cabinet
You can mount an EX3300 switch in a rack or cabinet such that the switch is recessed
inside the rack from the rack front by 2 inches. You can use the 2-in.-recess front brackets
provided in the separately orderable four-post rack-mount kit to mount the switch in a
recessed position.
Reasons that you might want to mount the switch in a recessed position include:
•
You are mounting the switch in a cabinet and the cabinet doors will not close completely
unless the switch is recessed.
•
The switch you are mounting has transceivers installed in the uplink ports—the
transceivers in the uplink ports protrude from the front of the switch.
