7. Have a second person secure the switch to the rack by using the appropriate
screws. Tighten the screws.
8. 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.
9. We recommend that you insert dust covers in any unused ports.

Mounting an EX4500 Switch on Four Posts in a Rack or Cabinet
You can mount an EX4500 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 EX4500
Switch on Two Posts in a Rack or Cabinet” on page 66.
NOTE: If you are mounting the switch on four posts, ensure that the rack is 21.5 in.
through 31.5 in. deep if you will mount the switch flush with the rack front and that
the rack is 23.5 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 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).
■ Have two persons available to mount the switch. One person will support the
switch in a level position, and the second person will secure the switch to the
rack.
