Cisco Nexus 7009 Chassis Clearances
The Cisco Nexus 7009 chassis has different clearance requirements for installations with four-post racks or
cabinets, two-post racks with front-mount brackets, and two-post racks with center-mount brackets.
For four-post rack or cabinet installations, the chassis requires the following clearances (see Figure 135:
Clearances Required for a Front-Mounted Cisco Nexus 7009 Chassis in a Four-Post Rack, on page 192):
• Front clearance requires both of the following:
• Cabling area of 7.5 inches (19.1 cm) between the front of the chassis and the inside surface of the
cabinet or rack (this area can include the optional cable management frames)
• Maintenance area of 24 inches (61.1 cm) between the front of the rack or cabinet and the next object
in the cold aisle.
You might need to increase the maintenance area to accommodate a wide mechanical lift used to move the
chassis to or from the rack.
Note
• Rear clearance includes both of the following:
• Cabling area of 7 inches (17.8 cm) between the rear of the chassis and the inside surface of the
cabinet or rack
• Maintenance area of 24 inches (61.1 cm) between the rear of the rack or cabinet and the next object
in the hot aisle
• Side clearance of 11 inches (27.9 cm) for air flow on each side of the chassis.
