Juniper EX4300 Hardware Guide

You can mount the switch on two posts of either a two-post rack or a four-post rack by
using the mounting brackets provided with the switch. See “Mounting an EX4300 Switch
on Two Posts of a Rack or Cabinet” on page 167.
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:
To ensure that the protective earthing terminal is accessible through the
opening in the rear mounting-blade:
•
Ensure that the rack is 27.5 in. (70 cm) through 30.5 in. (77.5 cm) deep if
you are mounting the switch flush with the rack front on four posts of a
rack.
•
Ensure that the rack is 29.5 in. (75 cm) through 32.5 in. (82.5 cm) deep if
you will mount the switch 2 in. recessed from the rack front.
Before mounting the switch on four posts of a rack:
•
Verify that the site meets the requirements described in “Site Preparation Checklist
for EX4300 Switches” on page 87.
•
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 283, with particular attention
to “Chassis Lifting Guidelines” on page 292.
•
Remove the switch from the shipping carton (see “Unpacking an EX4300 Switch” on
page 161).

•
Phillips (+) screwdriver, number 2 (not provided)

6 flat-head 4-40 Phillips mounting screws (provided with the four-post rack-mount
kit)
