Juniper EX3300 Complete Hardware Guide

Mounting an EX3300 Switch
You can mount the switch:
•
On two posts in a 19-in. rack or cabinet by using the mounting brackets provided with
the switch.
•
On four posts in a 19-in. rack or cabinet by using the separately orderable four-post
rack-mount kit.
•
In a position recessed 2 in. from the front of a 19-in. rack or cabinet by using the
2-in.-recess front brackets in the separately orderable four-post rack-mount kit. You
can mount the switch in this recessed position on two-post or four-post racks and
cabinets.
•
On a desk or other level surface by using rubber feet. The switch is shipped with four
rubber feet to be used to stabilize the chassis on a desk or other level surface.
•
On a wall by using the separately orderable wall-mount kit.
WARNING: When mounting an EX3300 switch chassis in a vertical position,
orient the front panel of the chassis downward to ensure proper airflow
and meet safety requirements in the event of a fire.
The holes in the mounting brackets are placed at 1 U (1.75 in. or 4.45 cm.) apart so that
the switch can be mounted in any rack or cabinet that provides holes spaced at that
distance.
See the Related Documentation for detailed descriptions of the various rack or cabinet
mounting options.

Mounting an EX3300 Switch on Two Posts in a Rack or Cabinet
You can mount the 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
EX3300 Switch on Four Posts in a Rack or Cabinet” on page 87.
