Cisco Systems ASR9001s, 9001S manual Air Flow Guidelines for Enclosed Rack Installation

Chapter 1 Preparing for Installation

Site Requirement Guidelines

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 aound 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.

Figure 1-8shows the side and rear chassis air flow clearance requirements for mounting the
