Site Requirement Guidelines
4-Post Enclosed Rack with Perforated Sides
Item c in Figure 1-17 shows a free-standing 4-post enclosed rack with perforated sides and two mounting
posts in the front.
Caution Do not install the Cisco ASR 9000 Series 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 overtemperature condition inside the router.
Air Flow Guidelines for Enclosed Rack Installation
Follow these guidelines when installing the CiscoASR 9000 Series Routers in a 4-post enclosed rack.
