Site Requirements
If you are installing your Catalyst 6500 series switch in an enclosed or partially enclosed rack, we
strongly recommend that you verify that your site meets the following guidelines:

Selecting the Proper Rack-Enclosure or Cabinet
Cisco Systems has identified two rack-enclosures that are determined to be Cisco-compatible:
Panduit Corporation—The Net-Access Cabinet (p/n CN4-1) is determined to be Cisco-compatible for
the Catalyst 6500 series product line. Contact Panduit Corporation for further information on this rack
enclosure. Their corporate website is http://www.panduit.com. Their Customer Service and Technical
Support phone number is 800 777-3300.
Chatsworth Products, Inc.—The N-Series TeraFrame Network Cabinet (p/n NF2K-113C-C42) is
determined to be Cisco-compatible for the Catalyst 6500 series product line. Contact Chatsworth
Products, Inc. for further information on this rack enclosure. Their corporate website is
http://www.chatsworth.com. Their Customer Service and Technical Support phone number is 800
834-4969 (Monday to Friday, 5 a.m. to 5 p.m., (0500 to 1700) Pacific Time).
Catalyst 6500 Series Switches Installation Guide
2-4
Verify that there is a minimum of 6 inches (15 cm) of clearance between the sides of the rack and
both the chassis air intake grill and the chassis air exhaust grill.
Verify that the ambient air temperature within the enclosed or partially enclosed rack is within the
chassis operating temperature limits. After installing the chassis in the rack, power up the chassis
and allow the chassis temperature to stabilize (approximately 2 hours). Measure the ambient air
temperature at the chassis air intake grill and at the chassis air exhaust grill by positioning an
external temperature probe approximately 1 inch (2.5 cm) away from the grills, in line with the
chassis slot occupied by the supervisor engine.
–
If the ambient intake air temperature is less than 104°F (40°C), the rack meets the intake air
temperature criterion.
–
If the ambient intake air temperature exceeds 104°F (40°C), the system might experience minor
temperature alarms and is in danger of overheating.
–
If the ambient intake air temperature equals or is greater than 131°F (55°C), the system will
experience a major temperature alarm and shut down.
Verify that the enclosed or partially enclosed rack allows an adequate flow of air through the switch
chassis as follows:
If the difference between the measured intake air temperature and the exhaust air temperature
–
does not exceed 10°C, there is sufficient airflow in the rack.
If the difference in air temperature exceeds 10°C, there is insufficient airflow to cool the chassis.
–
The 10°C temperature differential between the intake and the exhaust must be determined by
taking measurements using external digital temperature probes. Do not use the chassis internal
temperature sensors to measure the temperature differential.
Plan ahead. Your Catalyst 6500 series switches currently installed in an enclosed or partially
enclosed rack might meet ambient air temperature and air flow requirements now. However, if you
add more chassis to the rack or you add more modules to a chassis in the rack, the additional heat
generated might cause the ambient air temperature within the rack to exceed 104°F (40°C) and can
cause minor alarms.
