Overview
General Requirements
The cabinet or rack must be a standard 19-in. four-post EIA cabinet or rack, with mounting posts that conform
to English universal hole spacing per section 1 of ANSI/EIA-310-D-1992. See the
Perforated Cabinets, on page 13
The cabinet or rack must also meet the following requirements:
• The minimum vertical rack space per chassis should be 2 RU (rack unit), equal to 1.75 in. (4.4 cm).
• The width between the rack-mounting rails must be at least 17.75 in. (45.1 cm). This is the distance
between the two front rails.
• For four-post EIA cabinets (perforated or solid-walled):

EIA (4-post)
• Cisco MDS 9396V switches are compatible with Cisco racks (such as Cisco R42612) and PDUs. Optional
jumper power cords are available for use in a cabinet.
Requirements Specific to Perforated Cabinets
In addition to the requirements listed in the General Requirements for Cabinets and Racks section, perforated
cabinets 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. 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 9396V 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.

Requirements Specific to Solid-Walled Cabinets, on page
• 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 rail and the outside face of the back
mounting rail should be 23.5 to 34.0 in. (59.7 to 86.4 cm) to allow for installation with the Cisco
rack mounting kit.
• There should be a minimum of 2.5 in. (6.4 cm) of clear space between the side edge of the chassis
and the side wall of the cabinet. No sizable flow obstructions should be immediately in the way of
the chassis air intake or exhaust vents.
• 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).
• The airflow and cooling are adequate and there is sufficient clearance around the air vents on the
switch, as described in Technical Specifications. This is particularly important to verify if you are
installing the switch in an enclosed cabinet.
• No clearance is required between the chassis and the sides of the rack or cabinet (no side airflow).
• The rack meets the minimum rack load ratings per rack unit (RU) listed in the following table.
