Mounting an EX3300 Switch on a Desk or Other Level Surface
You can mount an EX3300 switch on a desk or other level surface by using the four rubber
feet that are shipped with the switch. The rubber feet stabilize the chassis.
Before mounting the switch on a desk or other level surface:
•
Verify that the site meets the requirements described in “Site Preparation Checklist
for EX3300 Switches” on page 55.
•
Place the desk 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:
•
4 rubber feet to stabilize the chassis on the a desk or other level surface (provided in
the accessory box in the switch carton)
To mount a switch on a desk or other level surface:
1. Remove the switch from the shipping carton (see “Unpacking an EX3300 Switch” on
page 82).
2. Turn the chassis upside down on the desk or the level surface where you intend to
mount the switch.
3. Attach the rubber feet to the bottom of the chassis, as shown in Figure 28 on page 92.
4. Turn the chassis right side up on the desk or the level surface.
