Cisco MDS 9148T User Manual

For four-post EIA cabinets (perforated or solid-walled):
• The distance between the front door and front mounting posts should be a minimum of 3 in. (7.6 cm) to
allow for the bend radius of FC port fibre-optic patch cables.
• The distance between the outside face of the front mounting post and the outside face of the back mounting
post should be 26 to 32 in. (66 to 81 cm) to allow for installation with the Cisco rack mounting kit.
• The distance between the rear of the chassis and the perforated rear door of the cabinet (required for
airflow in the cabinet, if used) should be a minimum of 3.0 in. (7.6 cm).
• No clearance is required between the chassis and the sides of the rack or cabinet (no side airflow).
• The amount of clearance required for interface cables is 3 in. [7.6 cm] minimum and module handles is
1 in. [25 mm] minimum.
• Optional jumper power cords are available for use in a cabinet.

Note
Requirements Specific to Perforated Cabinets
In addition to the requirements listed in the General Requirements for Cabinets and Racks, on page 15 section,
perforated cabinets with front-to-back airflow must meet the following requirements:
• The front and rear doors must have at least a 60 percent open area perforation pattern, with at least 15
sq. in. (96.7 sq cm) of open area per rack unit of door height.
• We recommend that the roof be perforated with at least 20 percent open area, unless the cabinet only
contains Cisco MDS 9148T switch, in which case the roof does not have to be perforated.
• We recommend an open or perforated cabinet floor to enhance cooling but it is not required.
