Mount the EX9214

NOTE:

A fully loaded chassis weighs approximately 350 lb (158.76 kg). We strongly recommend that you use

a mechanical lift to lift the chassis, and remove all the components from the chassis before mounting.

NOTE:

While mounting multiple units on a rack, mount the heaviest unit at the bottom and mount the other

units from the bottom to the top in order of decreasing weight.

To install the switch using a mechanical lift:

1. Safely remove all components—power supplies, Switch Fabric (SF) module, fan tray, air filter, and line cards—from the

chassis.

2. Ensure that the rack is properly secured to the building in its permanent location. Ensure that the installation site allows

adequate clearance for both airflow and maintenance. For details, see the Complete Hardware Guide for EX9214

Switches.

3. Ensure that the mounting shelf is installed to support the weight of the switch.
