Mounting an EX4200 Switch on Four Posts in a Rack or Cabinet
You can mount an EX4200 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 EX4200 Switch
on Two Posts in a Rack or Cabinet” on page 160 .
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-mounting
brackets provided in the separately orderable four-post rack-mount kit.
NOTE: If you are mounting an EX4200 switch on four posts, ensure that the
rack is 27.5 in. through 30.5 in. deep if you will mount the switch flush with
the rack front and that the rack is 29.5 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
mounting-blade.
Before mounting the switch on four posts in a rack:
•
Verify that the site meets the requirements described in “Site Preparation Checklist
for EX4200 Switches” on page 61 .
• 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 267 , with particular attention
to “Chassis Lifting Guidelines for EX4200 Switches” on page 277 .
• Remove the switch from the shipping carton (see “Unpacking an EX4200 Switch” on
page 153 ).
Ensure that you have the following parts and tools available:
• Phillips (+) screwdriver, number 2
•
6 flat-head 4-40 mounting screws (provided with the four-post rack-mount kit)
•
12 flat-head 4x6-mm Phillips mounting screws (provided with the four-post rack-mount
kit)
• One pair each of flush or 2-in.-recess front-mounting brackets (provided with the
four-post rack-mount kit)
•
One pair of side mounting-rails
• One pair of rear mounting-blades (provided with the four-post rack-mount kit)
