Juniper EX Series Complete Hardware Guide

Mounting an EX-series Switch on a Desk or Other Level Surface
You can mount an EX-series switch on a desk or other level surface by using the 4
rubber feet that are shipped with the switch. The rubber feet stabilize the chassis.
Before mounting an EX-series switch on a desk or other level surface:
■ Verify that the site meets the requirements described in “Site Preparation
Checklist for EX-series Switches” on page 49.
■ 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 130, with particular
attention to “Chassis Lifting Guidelines” on page 147.
■ Remove the switch from the shipping carton (see “Unpacking an EX-series
Switch” on page 62).
■ Ensure you have the following tools and parts available to mount an EX-series
switch on a desk or other level surface:
■ Phillips (+) screwdriver, number 2
■ Rubber feet to stabilize the chassis on the a desk or other level surface
■ Dust covers for ports (for EX 4200-24F switches only; optional)
To mount the EX-series switch on a desk or other level surface:
1. Turn the chassis upside down on the desk or the level surface where you intend
to mount the switch.
2. Attach the rubber feet to the bottom of the chassis, as shown in
Figure 30 on page 66.
3. Turn the chassis right side up on the desk or the level surface.
4. If it is an EX 4200-24F switch, we recommend you insert dust covers in unused
SFP ports.
