Juniper EX Series Mounting

CAUTION: If you are installing more than one switch in a rack or cabinet, install the
first switch at the bottom of the rack.
To install the switch using a mechanical lift (see Figure 1):
1. Ensure that the rack or cabinet is placed in its permanent location and is secured
to the building. Ensure that the installation site allows adequate clearance for
both airflow and maintenance. For details, see Clearance Requirements for
Airflow and Hardware Maintenance for an EX8208 Switch.
2. Load the switch onto the lift, making sure it rests securely on the lift platform.

3. Using the lift, position the switch in front of the rack or cabinet, centering it in
front of the adjustable mounting brackets and/or power cord tray installed in the
rack.
4. Lift the chassis approximately 0.75 in. (1.9 cm) above the surface of the adjustable
mounting brackets/power cord tray. Position the chassis in the rack as close as
possible to resting on the support that the mounting brackets and/or power cord
tray provide.
