Manage Fans
Chassis fan management is a continuous process of monitoring Chassis fans and
temperature data to maintain optimal operating temperatures inside the Chassis. The
Chassis Power Entry Module (PEM) monitors the fans and sends Sensor Data Reports to
the Shelf Manager. The Shelf Manager evaluates the data received from the PEM with
temperature data received from other Chassis sensors and adjusts fan speeds as needed
to ensure the Chassis and Chassis Modules are operating within OEM temperature
specifications.
Access Chassis Fan Data and Settings
Chassis fans data and settings are accessed on the Power Entry Page.

temperature requirements of the modules installed in the Chassis. Fan speeds can be set
manually by the user (see
