Because of the size and weight of the switch, we strongly recommend using a mechanical li to install
the switch.
CAUTION: Do not install line cards in the chassis unl aer you mount the chassis
securely on a rack or cabinet.
CAUTION: Before front-mounng the switch on a rack or cabinet, have a qualied
technician verify that the rack or cabinet is strong enough to support the weight of the
switch and is adequately supported at the installaon site.
CAUTION: If you are installing more than one switch in a rack or cabinet, install the rst
switch at the boom of the rack.
To install the switch using a mechanical li:
1. Aach the ESD grounding strap to your bare wrist and connect the strap to the ESD point on the
chassis.
2. Ensure that the rack or cabinet is placed in its permanent locaon and is secured to the building.
Ensure that the installaon site allows adequate clearance for both airow and maintenance.
3. Load the switch onto the li, making sure it rests securely on the li plaorm.
