Juniper Networks manual Installing the EX8208 Switch Chassis Using a Mechanical Lift

Complete Hardware Guide for EX8208 Ethernet Switches

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 48 on page 142):

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” on page 101.

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.

5.In a four-post rack, carefully slide the switch onto the adjustable mounting brackets until the front-mounting brackets (“ears”) attached to the chassis contact the rack
