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 359 .
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 97 .
•
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 203 , with particular attention to Chassis and
Component Lifting Guidelines.
•
Remove the switch from the shipping carton (see “Unpacking an EX4300 Switch” on page 354 ).
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)
