You can mount an EX3200 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:
To mount the switch in a recessed position on four posts, follow the instructions in Mounting an EX3200 Switch on Four Posts in a Rack or Cabinet. To mount the switch in a recessed position on two posts, follow the instructions in Mounting an EX3200 Switch on Two Posts in a Rack or Cabinet.
