Mounting a J-EX4200 Switch on Four Posts in a Rack or Cabinet
You can mount a J-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 a J-EX4200 Switch
on Two Posts in a Rack or Cabinet” on page 92.
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 brackets
provided in the separately orderable four-post rack-mount kit.
NOTE: If you are mounting a J-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
bracket.
Before mounting the switch on four posts in a rack:
•
Verify that the site meets the requirements described in “Site Preparation Checklist
for J-EX4200 Switches” on page 57.
• 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 J-EX Series Switches” on page 171,
with particular attention to “Chassis Lifting Guidelines for J-EX4200 Switches” on
page 184.
• Remove the switch from the shipping carton (see “Unpacking a J-EX4200 Switch” on
page 88).
Ensure that you have the following parts and tools available:
•
Phillips (+) screwdriver, number 2
•
Flat-blade screwdriver if you are installing the switch in a rack with square, nonthreaded
holes
• 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 brackets
