Temperature Requirements
The fabric interconnect requires an operating temperature of 32 to 104 degrees Fahrenheit (0 to 40 degrees
Celsius). If the fabric interconnect is not operating, the temperature must be between -40 to 158 degrees
Fahrenheit (-40 to 70 degrees Celsius).
Humidity Requirements
Buildings in which the climate is controlled by air-conditioning in the warmer months and by heat during the
colder months usually maintain an acceptable level of humidity for the fabric interconnect equipment. However,
if the fabric interconnect is located in an unusually humid location, use a dehumidifier to maintain the humidity
within an acceptable range.
Altitude Requirements
Altitude rating is based on power supply installed; see critical components list in the system CB report for
altitude rating.

Page 2: Dust And Particulate Requirements
Preparing for Installation Dust and Particulate Requirements Dust and Particulate Requirements Exhaust fans cool power supplies and system fans cool fabric interconnects by drawing in air and exhausting air out through various openings in the chassis. However, fans also ingest dust and other particles, causing contaminant buildup in the fabric interconnect and increased internal chassis temperature. -
Page 3: Shock And Vibration Requirements
Preparing for Installation Shock and Vibration Requirements Caution If the wires exceed the recommended distances, or if wires pass between buildings, give special consideration to the effect of a lightning strike in your vicinity. The electromagnetic pulse that is caused by lightning or other high-energy phenomena can easily couple enough energy into unshielded conductors to destroy electronic fabric interconnects. -
Page 4: Airflow Requirements
Preparing for Installation Airflow Requirements Note For n+1 redundancy, you can use one or two power sources for the two power supplies. For n+n redundancy, you must use two power sources and connect each power supply to a separate power source. Note Some of the power supply modules have rating capabilities that exceed the fabric interconnect requirements. -
Page 5: Rack And Cabinet Requirements
Work with your cabinet vendors to determine which of their cabinets meet the following requirements or see the Cisco Technical Assistance Center (TAC) for recommendations: • Use a standard 19-inch (48.3-cm), four-post Electronic Industries Alliance (EIA) cabinet or rack with mounting rails that conform to English universal hole spacing per section 1 of the ANSI/EIA-310-D-1992 standard. - Page 6 Preparing for Installation Clearance Requirements Chassis Depth of the chassis Vertical rack-mount posts and rails Maximum extension of the bottom-support rails 36.0 in (91.0 cm) Chassis width Depth of the front clearance area (equal to the depth of the chassis). 17.3 in (43.9 cm) Width of the front clearance area (equal to the width of the chassis with two rack-mount...
