Cabinet and Rack Requirements
This section provides the Cisco MDS 9000 Series switches requirements for the following types of cabinets
and racks in an external ambient air temperature range of 0 to 40°C:
• Standard perforated cabinets
• Solid-walled cabinets with a roof fan tray (bottom to top cooling)
• Standard open racks
• Telco racks
If you are selecting an enclosed cabinet, we recommend one of the thermally validated types listed above:
standard perforated or solid-walled with a fan tray.
Note
General Requirements for Cabinets and Racks
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 Requirements Specific to
Perforated Cabinets and Requirements Specific to Solid-Walled Cabinets sections.
The cabinet or rack must also meet the following requirements:
• The minimum vertical rack space per chassis should be 1 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):
• 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.
