Hardware Installation Guide for the Cisco 4451-X Integrated Services Router
OL-27644-01
Chapter 1 Overview of the Cisco 4451-X Integrated Services Router
About Slots and Interfaces
Fans, Ventilation, and Airflow
Chassis Ventilation
An internal fan tray consisting of 4 fans provides chassis cooling. An onboard temperature sensor
controls the fan speed. The fans are always on when the router is powered on. Under most conditions,
the fans operate at the slowest speed to conserve power and reduce fan noise. The fans operate at the
higher speeds when necessary under conditions of higher ambient temperature. To replace a fan tray, see
the “Replacing a Fan Tray” section on page 6-34.
