Remove a Fan Module

Fan modules provide server cooling to the motherboard and its components. The fan modules
are arranged in stacked pairs (a front row and a back row) to provide redundancy. If you remove
a fan module, replace it immediately.
Fan modules are hot-serviceable components. It is not necessary to power off the server
or to remove the server cover to service a fan module. However, depending on server rack
configuration, it might be necessary to partially extend the server from the rack to access the
fan modules. (Optional steps for partially extending the server from the rack are included in
this procedure.) Take care when partially extending the server from the rack during hot service.
Ensure that the cables at the back of the server do not become dislodged, particularly the power
cables. As an option, you can also perform this procedure using cold service.
