Mounting an EX4550 Switch in a Recessed Position in a Rack or Cabinet
You can mount an EX4550 switch in a recessedposition on twoposts 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 mount 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 doorsdo not closecompletely
unless the switch is recessed.
•
The switch you are mounting has an expansion module with transceivers installed in
it—the transceivers in the expansion module 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 EX4550 Switch on Two Posts in a Rack or Cabinet” on page 148 or “Mounting
an EX4550 Switch on Four Posts in a Rack or Cabinet” on page 151.
