Mounting an EX3200 or EX4200 Switch on Four Posts in a Rack or Cabinet

You can mount an EX3200 or EX4200 switch on four posts of a 19-in. rack or cabinet by using the separately orderable four-post rack-mount kit. (The remainder of this topic uses “rack” to mean “rack or cabinet.”)

You can mount the switch on two posts in either a two-post rack or a four-post rack by using the mounting brackets provided with the switch. See “Mounting an EX3200 or EX4200 Switch on Two Posts in a Rack or Cabinet” on page 118.

NOTE: If you need to mount the switch in a recessed position on either a two-post rack or a four-post rack, you can use the 2-in.-recess front brackets provided in the separately orderable four-post rack-mount kit.

NOTE: If you are mounting an EX4200 switch on four posts, ensure that the rack is

27.5in. through 30.5 in. deep if you will mount the switch flush with the rack front and that the rack is 29.5 in. through 32.5 in. deep if you will mount the switch 2 in. recessed from the rack front, thus ensuring that the protective earthing terminal is accessible through the opening in the rear bracket.

Before mounting the switch on four posts in a rack:

■Verify that the site meets the requirements described in “Site Preparation Checklist for EX3200 and EX4200 Switches” on page 81.

■Place the rack in its permanent location, allowing adequate clearance for airflow and maintenance, and secure it to the building structure.

■Read “General Safety Guidelines and Warnings for EX Series Switches” on page 207, with particular attention to “Chassis Lifting Guidelines for EX3200 and EX4200 Switches” on page 220.

■Remove the switch from the shipping carton (see “Unpacking an EX3200 or EX4200 Switch” on page 114).

Ensure that you have the following parts and tools available to mount the switch on four posts in a rack:

■Phillips (+) screwdriver, number 2

■6 flat-head 4-40 mounting screws (provided with the four-post rack-mount kit)

■12 flat-head 4x6-mm Phillips mounting screws (provided with the four-post rack-mount kit)
