For two-post rack installations with center-mount brackets, the chassis requires the following clearances (see
Figure 137: Clearances Required for a Center-Mounted Cisco Nexus 7009 Chassis in a Two-Post Rack, on
page 196):
• Front clearance of 37 inches (94.0 cm) for both of the following:
• Cabling area of 13.5 inches (34.3 cm) between the front of the posts (posts are 6 inches (15.2 cm)
behind the front of the chassis)
• Maintenance area of 26 inches (66.0 cm) in front of the cabling area for installing the chassis and
replacing modules.
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 of 26 inches (66.0 cm) behind the chassis for cable management and for replacing the
fan modules and power supplies.
• Side clearance of 11 inches (27.9 cm) for airflow on each side of the chassis.
