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.
To mount the switch in a recessed position on four posts, follow the instructions in
“Mounting an EX3300 Switch on Four Posts in a Rack or Cabinet” on page 71. To mount
the switch in a recessed position on two posts, follow the instructions in “Mounting an
EX3300 Switch in a Recessed Position in a Rack or Cabinet” on page 74.

Mounting an EX3300 Switch on a Desk or Other Level Surface
You can mount an EX3300 switch on a desk or other level surface by using the four rubber
feet that are shipped with the switch. The rubber feet stabilize the chassis.
Before mounting the switch on a desk or other level surface:
•
Verify that the site meets the requirements described in “Site Preparation Checklist
for EX3300 Switches” on page 41.
•
Place the desk in its permanent location, allowing adequate clearance for airflow and
maintenance, and secure it to the building structure.
•
Read “General Safety Guidelines and Warnings” on page 133, with particular attention
to “Chassis Lifting Guidelines for EX3300 Switches” on page 144.
