Preparing for Installation

Air Flow Guidelines

Cool air is circulated through the Cisco ASR 920 Series Router by fans located along the back side of
the router.
The internal fans maintain acceptable operating temperatures for the internal components by drawing in
cool air through the vents, and circulating the air through the chassis.
The direction of air flow is from front-to-back.
Figure 2-1
To ensure adequate air flow through the equipment rack, it is recommended that you maintain a
minimum clearance distance as mentioned below, at all times.
