Managing the cooling system
This section provides configuration, management, and monitoring information about router cooling systems.
Configuring the cooling system
Your router is
•Low and high temperature thresholds for modules and fan speeds
•Interval at which the system polls the temperature sensors on the module for a reading
NOTE
Auto control of fan speed is not monitored when cards are in interactive mode. Set fan speed to high to prevent
NOTE
Adjusting fan controls out of the default setting can negatively affect the efficient cooling of blades and may cause a blade to overheat and shutdown.
Changing temperature thresholds for modules and fan speeds
The cooling system includes fans that operate at four speeds: low, medium,
NOTE
Adjusting fan controls out of the default setting can negatively affect the efficient cooling of blades and may cause a blade to overheat and shutdown.

The low and high temperature thresholds allow the router to determine the speed at which the fans should operate. In general, the fans operate according to these guidelines:
•If the temperature of all modules falls between the low and high thresholds for a fan speed, the fan continues to operate at that speed.
