You can mount the switch on four posts in a four-post rack by using the mounting brackets
provided with the separately orderable four-post rack-mount kit. See “Mounting an
EX4550 Switch on Four Posts in a Rack or Cabinet” on page 151.
NOTE: If you need to mount the switch in a recessed position on two posts
of either a two-post rack or a four-post rack, you can use the 2-in.-recess
front mount brackets provided in the separately orderable four-post
rack-mount kit.
Before mounting the switch on two posts in a rack:
•
Verify that the site meets the requirements described in “Site Preparation Checklist
for EX4550 Switches” on page 71.
•
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” on page 253, with particular attention
to “Chassis Lifting Guidelines for EX4550 Switches” on page 263.
•
Remove the switch from the shipping carton (see Unpacking an EX4550 Switch).
Ensure that you have the following parts and tools available:
•

•
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 mount brackets if you will mount the switch in a recessed position
(brackets are part of the separately orderable four-post rack-mount kit).
•
Cover panels for module slots (provided in the accessory box shipped with the switch)
•
Dust covers for ports (provided in the accessory box shipped with the EX4550-32F
switches)
NOTE: One person must be available to lift the switch while another secures
