Chapter 1 Cisco XR 12410 Router Overview

Horizontal Cable Management Bracket

The blower module maintains acceptable operating temperatures for internal components by drawing cool air through a replaceable air filter into the switch fabric and alarm card cage, and then up through the line card and RP card cage. Figure 1-15illustrates the air flow path through the chassis.

To ensure that there is adequate air flow to prevent overheating inside the card cages, keep the front and back of the router unobstructed. We recommend at least 6 inches (15.24 cm) of clearance.

Caution You should inspect and clean the air filter one time per month (more often in dusty environments). Do not operate the router without an air filter installed.

The blower module controller card monitors and controls operation of three variable-speed fans in the blower module. The variable-speed feature allows quieter operation by running the fans at below maximum speed, while still providing adequate cooling to maintain an acceptable operating temperature inside the card cages.
