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” on page 68.
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” on page 43.
■ 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 145, with particular attention to “Chassis Lifting Guidelines for EX4500
Switches” on page 158.
■ Remove the switch from the shipping carton (see “Unpacking an EX4500 Switch”
on page 64).
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:
1. Place the switch on a flat, stable surface.
2. 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 23 on page 67.
