Remove fan modules (FMs) to replace a failed FM, or to access CMODs.
See Preparing the Server for Component Replacement.
Access fan modules (FMs) from the front of the server. A fan module in a failed state has a lit steady on amber-color Fault-Service Required LED.

Caution - Data Loss. Do not remove more than one fan module from a column while the system is in Main 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-side fan frame. |
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 overtemperature. 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. |
