Juniper EX3300 Complete Hardware Guide

Use the wall-mount kit from Juniper Networks to mount the switch on a wall. The
wall-mount kit is not part of the standard package and must be ordered separately.

Clearance Requirements for Airflow and Hardware Maintenance for EX3300 Switches
When planning the site for installing an EX3300 switch, you must allow sufficient
clearance around the installed switch (see Figure 13 on page 66).
