Chassis Clearances
For two-post rack installations with front-mount brackets, the chassis requires the following clearances
(see
Figure A-18
):
•
Front clearance requires both of the following:
–
Cabling area of 7.5 inches (19.1 cm) between the front of the chassis and the cold aisle (this
area can include the optional cable management frames)
–
Maintenance area of 28 inches (71.1 cm) in front of the cabling area for installing the chassis
and replacing modules
Note
You might need to increase the maintenance area to accommodate a wide mechanical lift
used to move the chassis to or from the rack.
•
Rear clearance requires 26 inches (66.0 cm) behind the chassis for cable management and for
replacing modules and power supplies
•
Side clearance recommendation depends on whether you use a rack or cabinet for the installation as
follows:
–
For cabinet installations, we recommend that you use 11 inches (27.9 cm) for airflow on each
side of the chassis.
–
For rack installations, we recommend 11 inches (27.9 cm) between the chassis and a wall or 6
inches (15.2 cm) between racks.
