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

You can mount an EX3200 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 Switch on Two Posts in a Rack or Cabinet.

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.

Before mounting the switch on four posts in a rack:

• Verify that the site meets the requirements described in Site Preparation Checklist for EX3200 Switches.
• 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, with particular attention to Chassis Lifting Guidelines for EX3200 Switches.
• Remove the switch from the shipping carton (see Unpacking an EX3200 Switch).

Ensure that you have the following parts and tools available:

• 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)
• One pair each of flush or 2-in.-recess front brackets
• One pair of side-rail brackets
• One pair of rear brackets
• Screws to secure the chassis and the rear brackets to the rack (not provided)

Note: One person must be available to lift the switch while another secures it to the rack.

Caution: If you are mounting multiple units on a rack, mount the heaviest unit at the bottom of the rack and mount the other units from the bottom of the rack to the top in decreasing order of the weight of the units.

1. Attach the front brackets (either the flush or the 2-in.-recess brackets) to the side-rail brackets using six 4-40 flat-head Phillips mounting screws. See Figure 1.

2. Place the switch on a flat, stable surface.
3. Align the side-rail brackets along the side panels of the switch chassis. Align the two holes in the rear of the side-rail brackets with the two holes on the rear of the side panel.
4. Insert 4x6-mm Phillips flat-head mounting screws into the two aligned holes and tighten the screws. Ensure that the remaining four holes in the side-rail brackets are aligned with the four holes in the side panel. See Figure 2.

5. Insert the 4x6-mm Phillips flat-head mounting screws into the remaining four holes in the side-rail brackets and tighten the screws.
6. Have one person grasp both sides of the switch, lift the switch, and position it in the rack, aligning the side-rail bracket holes with the threaded holes in the front post of the rack. Align the bottom hole in both the mounting brackets with a hole in each rack rail, making sure the chassis is level. See Figure 3.

7. Have a second person secure the front of the switch to the rack by using the appropriate screws for your rack.
8. Slide the rear brackets into the side-rail brackets. See Figure 4.

9. Attach the rear brackets to the rear post by using the appropriate screws for your rack. Tighten the screws.
10. Ensure that the switch chassis is level by verifying that all the screws on the front of the rack are aligned with the screws at the back of the rack.
