The cabinet or rack must also meet the following requirements for the Cisco MDS 9513 chassis:

•The minimum vertical rack space per chassis:

–Cisco MDS 9513 chassis: 24.5 inches (62.2 cm) or 14 RU, height with required rack mount support is 15 RU.

•The distance between the rack-mounting rails for four-post EIA racks must be at least 26.56 inches (67.46 cm). For more information, see “Installing the Cisco MDS 9513 Director in a Rack” section on page 2-7.

•The minimum spacing for four-post EIA cabinets (perforated or solid-walled):

–To ensure the minimum bend radius for fiber-optic cables, the front mounting rails of the cabinet should be offset from the front door by a minimum of 3 inches (7.6 cm), and a minimum of 5 inches (12.7 cm) if cable management brackets are installed on the front of the chassis.

–A minimum of 4.0 inches (10.16 cm) of clear space between the side edge of the chassis and the side wall of the cabinet. No sizeable flow obstructions should be immediately in the way of the chassis air intake or exhaust vents.

Note Optional jumper power cords are available for use in a cabinet. See the “Jumper Power Cord” section on page E-11.
