Replacing Fan Modules
The seven fan modules in the server are numbered as shown in
Serviceable Component Locations, on page
Each fan module has a fault LED next to the fan connector on the motherboard. This LED lights green when
the fan is correctly seated and is operating OK. The LED lights amber when the fan has a fault or is not
correctly seated.
