Access this component directly from the front of the server. Remove a fan module (FM) to replace it when it has failed, or remove it as part of the process for accessing CMODs. FMs are hot-service components; however, accessing CMODs is a warm or cold-service procedure (for more information, see Remove a CMOD).
Before You Begin
For component serviceability, locations, and designations, seeAbout System Components.
A fan in a failed state has a lit amber-color Service Action Required indicator.
Caution - Data Loss. Do not remove more than one fan module from a column while the system is in full power mode. This action removes power from the CMODs and causes an immediate shutdown. On an eight-CMOD system, this applies to all fan modules. On a four-CMOD system, this applies to the fan modules in the left-hand fan frame (CMODs 0-3).
Caution - Electrical hazard. During a hot-service procedure, voltage is present. Do not reach into the vacant fan module slot with your hand or any object. Do not touch the exposed CMOD fan module power connector.
When the fan is removed from the slot, a hinged air vane drops down to close the slot. The vane maintains system cooling and prevents a disruption of server airflow during hot service.
Caution - Server over-temperature. The slot's air vane maintains system cooling by preventing a disruption of server airflow. Do not open the air vane when the system is running.
