Mounting an EX4300 Switch on Two Posts of a Rack or Cabinet
You can mount an EX4300 switch on two posts of a 19-in. rack (either a two-post or a
four-post rack) or a 19-in. cabinet by using the mounting brackets provided with the
switch. (The remainder of this topic uses rack to mean rack or cabinet.)
You can mount the switch on four posts of a four-post rack by using the mounting brackets
provided with the separately orderable four-post rack-mount kit. See “Mounting an
EX4300 Switch on Four Posts of a Rack or Cabinet” on page 169.
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-mounting brackets provided in the separately orderable four-post
rack-mount kit.
Before mounting the switch on two 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).
Ensure that you have the following parts and tools available:
Phillips (+) screwdriver, number 2 (not provided)
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-mounting brackets if you will mount the switch in a recessed position
(part of the separately orderable four-post rack-mount kit)
Cover panels for uplink module and power supply slots (provided)
