Mounting an EX4300 Switch in a Recessed Position in a Rack or Cabinet
You can mount an EX4300 switch in a recessed position on two posts of either a two-post
rack or a four-post rack such that the switch is recessed inside the rack from the rack
front by 2 inches. To mount the switch in a recessed position, use the front-mounting
brackets provided in the separately orderable four-post rack-mount kit.
Reasons to mount the switch in a recessed position include:
•
You are mounting the switch in a cabinet and the cabinet doors do not closecompletely
unless the switch is recessed.
•
The switch you are mounting has an uplink module with transceivers installed in it—the
transceivers in the uplink module ports protrude from the front of the switch.
To mount the switch in a recessed position, on two-posts or on four-posts, follow the
instructions in “Mounting an EX4300 Switch on Two Posts of a Rack or Cabinet” on
page 167 or “Mounting an EX4300 Switch on Four Postsof a Rack or Cabinet” on page 169.
