Mounting an EX4500 Switch on Two Posts in a Rack or Cabinet
You can mount an EX4500 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 EX4500 Switch on Four Posts in a Rack or Cabinet.
Before mounting the switch on two posts in a rack:
- Verify that the site meets the requirements described in Site Preparation Checklist for EX4500 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 EX4500 Switches.
- Remove the switch from the shipping carton (see Unpacking an EX4500 Switch).
Ensure that you have the following parts and tools available:
- Phillips (+) screwdriver, number 2
- 2 mounting brackets and 20 mounting screws (provided in the accessory box shipped with the switch)
- Screws to secure the chassis to the rack (not provided)
- Dust covers for ports
 | Note: One person must be available to lift the switch while another secures the switch to the rack. |
 | Caution: If you are mounting multiple units on the rack, mount the heaviest unit at the bottom and mount the others from bottom to top in order of decreasing weight. |
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 or
rear of the side panels of the switch chassis depending on whether
you are front-mounting or rear-mounting the switch. See Figure 1.
Figure 1: Attaching the Mounting Bracket Along the Front of the Switch
- 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.
- We recommend that you insert dust covers in any unused ports.
