Mounting an EX3300 Switch on Four Posts in a Rack or Cabinet
You can mount an EX3300 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 EX3300 Switch
on Two Posts in a Rack or Cabinet” on page 84.
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.
Before mounting the switch on four posts in a rack:
•
Verify that the site meets the requirements described in “Site Preparation Checklist
for EX3300 Switches” on page 55.
•
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 149, with particular attention
to “Chassis Lifting Guidelines for EX3300 Switches” on page 163.
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)
•
8 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
•
One pair of side mounting-rails
•
One pair of rear mounting-blades
•
Screws to secure the chassis and the rear mounting-blades to the rack (not provided)
