Rack-Mounting and Air Flow Clearance Guidelines

Enclosed Rack with Perforated Sides

Item c in
rack with perforated sides and two mounting posts in the front.
Caution Do not install the Cisco ASR 9001 Router in any type of fully-enclosed rack that does not have the required
perforated sides or doors; the router requires an unobstructed flow of cooling air to maintain acceptable
operating temperatures for its internal components. Installing the router in any type of fully-enclosed rack
without proper perforation could disrupt the air flow, trap heat next to the chassis, and cause an
over-temperature condition inside the router.
Air Flow Guidelines for Enclosed Rack Installation
To install a Cisco ASR 9001 Router in a 4-post enclosed cabinet, the front and rear doors of the cabinet must
be removed or be perforated with a minimum of 65% open area (70% for ETSI 800mm racks).
If you are mounting the chassis in a 4-post enclosed cabinet, ensure that you have these clearances around the
chassis:
• Rear: Minimum of 3.15 inches (8.00 cm) of clearance
• Sides: Minimum of 6 inches (15.24 cm) of clearance on each side of the chassis.
