"Cisco MDS 9000 Family Telco and EIA Shelf Bracket" section on page
Plan your site configuration and prepare the site before installing the switch. The recommended site
planning tasks are listed in
Ensure there is adequate space around the switch to allow for servicing the switch and for adequate
airflow (airflow requirements are listed in
Ensure the air-conditioning meets the heat dissipation requirements listed in
"Technical Specifications."
Ensure the cabinet or rack meets the requirements listed in
Installation."
If the front cabinet mounting rails are not offset from the front door or bezel panel by a minimum
of 3 in. (7.6 cm), and a minimum of 5 in. (12.7 cm) if cable management brackets are installed
on the front of the chassis, the chassis should be mounted rear-facing to ensure the minimum
bend radius for fiber-optic cables. See
Front Clearance" section on page
Jumper power cords are available for use in a cabinet. For more information, see the

Ensure the chassis is adequately grounded. If the switch is not mounted in a grounded rack, we
recommend connecting both the system ground on the chassis and the power supply ground to an
earth ground.
Ensure the site power meets the power requirements listed in
Specifications." If available, you can use an uninterruptible power supply (UPS) to protect against
power failures.
Avoid UPS types that use ferroresonant technology. These UPS types can become unstable
with systems such as the Cisco MDS 9000 Family, which can have substantial current draw
fluctuations because of fluctuating data traffic patterns.
