Mounting an EX3200 or EX4200 Switch on Two Posts in a Rack or Cabinet
You can mount an EX3200 or EX4200 switch on two posts of a 19-in. rack or cabinet by using the mounting brackets provided with the switch. (The remainder of this topic uses “rack” to mean “rack or cabinet.”)
You can mount the switch on four posts of a four-post rack by using the mounting brackets provided with the separately orderable four-post rack-mount kit. See Mounting an EX3200 or EX4200 Switch on Four 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 an EX3200 or EX4200 switch on two posts in a rack:
- Verify that the site meets the requirements described in Site Preparation Checklist for EX3200 and EX4200 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 for EX Series Switches, with particular attention to Chassis Lifting Guidelines for EX3200 and EX4200 Switches.
- Remove the switch from the shipping carton (see Unpacking an EX3200 or EX4200 Switch).
Ensure that you have the following parts and tools available:
- Phillips (+) screwdriver, number 2
- 2 mounting brackets and 8 mounting screws (provided in the accessory box shipped with the switch)
- Screws to secure the chassis to the rack (not provided)
- 2-in.-recess front brackets if you will mount the switch in a recessed position (brackets are from the separately orderable four-post rack-mount kit).
- Dust covers for ports (for EX4200-24F switches only; optional)
![]() | Note: One person must be available to lift the switch while another secures the switch to the rack. |
![]() | Caution: If you are mounting multiple switches on a rack, mount a switch in the bottom of the rack first and proceed to mount the rest of the switches from bottom to top. |
To mount the switch on two posts in a rack:
- Place the switch on a flat, stable surface.
- Align the mounting brackets along the front, rear,
or center of the side panels of the switch chassis depending on how
you want to mount the switch. For example, if you want to center-mount
the switch, align the brackets along the centers of the side panel.
See Figure 1.
Figure 1: Attaching the Mounting Bracket Along the Front of the Switch


Note: If you need to mount the switch in a recessed position, use the 2-in.-recess front mount brackets from the separately orderable four-post rack-mount kit.
- Align the bottom holes in the mounting brackets with holes on the side panels of the switch chassis.
- Insert mounting screws into the aligned holes. Tighten the screws.
- Ensure that the other holes in the mounting brackets are aligned with the holes in the side panels. Insert a screw in each hole and tighten the screws.
- Have one person grasp both sides of the switch,
lift the switch, and position it in the rack, aligning the mounting
bracket holes with the threaded holes in the rack or cabinet rail.
Align the bottom hole in both the mounting brackets with a hole in
each rack rail, making sure the chassis is level. See Figure 2.
Figure 2: Mounting the Switch on Two Posts in a Rack

- Have a second person secure the switch to the rack by using the appropriate screws. Tighten the screws.
- Ensure that the switch chassis is level by verifying that all screws on one side of the rack are aligned with the screws on the other side.
- If the switch is an EX4200-24F model, we recommend that you insert dust covers in any unused SFP ports.
