System Fans

Four fans provide cooling for the chassis. These fans circulate air through the
chassis as a means of lowering the chassis internal temperature. The SC217 system
fans are easy to change modules. There is no need to uninstall any other parts
inside the system when replacing fans, and no tools are required for installation.
Optional Fan Confi gurations
The SC217H model chassis is designed so that the default confi guration of the
system is for each motherboard to control two fans. Each motherboard node in
the chassis is connected to the backplane through the adapter card, mounted in
the motherboard node drawer. In the event that one of the motherboard drawers is
removed, then the remaining motherboard will operate both fans.
