• A minimum of 2.5 in. (6.4 cm) of clear space should exist between the side edge of the fabric
interconnect and the side wall of the cabinet. No sizeable flow obstructions should be immediately
in the way of fabric interconnect air intake or exhaust vents.
Optional jumper power cords are available for use in a cabinet.
Note
Requirements Specific to Perforated Cabinets
A perforated cabinet is defined here as a cabinet with perforated front and rear doors and solid side walls. In
addition to the requirements listed in the General Requirements for Cabinets and Racks, on page 18, 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
square inches of open area per rack unit of door height.
• The roof should be perforated with at least a 20 percent open area.
• The cabinet floor should be open or perforated to enhance cooling.
The Cisco R Series racks meet or exceed all these requirements.
Requirements Specific to Standard Open Racks
In addition to the requirements listed in the , if mounting the chassis in an open rack (no side panels or doors),
the minimum vertical rack space per chassis must be one RU (rack unit), equal to 1.75 in. (4.4 cm).
The Cisco R Series racks meet or exceed all these requirements.
Cable Management Guidelines
To help with cable management, you might want to allow additional space in the rack above and below the
chassis to make it easier to route as many as 56 fiber or copper cables through the rack.
Unpacking and Inspecting the Cisco UCS Fabric Interconnect
When handling fabric interconnect components, wear an ESD strap and handle modules by the carrier edges
only. An ESD socket is provided on the fabric interconnect. For the ESD socket to be effective, the fabric
interconnect must be grounded through the power cable, the chassis ground, or the metal-to-metal contact
with a grounded rack.
Caution
Optional: Keep the shipping container in case the fabric interconnect requires shipping in the future.
