Rack-Mounting Guidelines

Caution If the rack is on wheels, ensure that the brakes are engaged or the rack is otherwise stabilized.

Before rack-mounting the chassis, ensure that the cabinet or the rack meets the following requirements:

•The specifications listed in the “Cabinet and Rack Requirements” section on page C-1.

•The depth of the rack between the front-mounting and rear-mounting rails is fixed at 18 inches (45.7 cm).

•The depth of the rack between the front-mounting and rear-mounting rails is fixed at 26.56 inches (67.4 cm) for a Cisco MDS 9513 Director.

•The cabinet or rack-mounting rails are nonthreaded.

•The airflow and cooling are adequate and there is sufficient clearance around the air vents on the Cisco MDS 9509 Director, as described in Appendix D, “Technical Specifications.” This is particularly important to verify if you are installing the switch in an enclosed cabinet.

•The rack has sufficient vertical clearance for the chassis and any desired clearance for the installation process. The Cisco MDS 9500 Shelf Bracket Kit does not consume any RU when installed.

•The rack meets the minimum rack load ratings of 45 lb (20.41 kg) per rack unit (RU) for the Cisco MDS 9509 Director.
