System Cooling
Four 8-cm fans provide cooling for the system. The system fans are easy-to-
change modules. There is no need to uninstall any other parts inside the system when
replacing fans. These fans are NOT redundant and must be replaced when they fail.
It is very important that the chassis top cover is installed for the cooling air to circulate properly
through the chassis and cool the components.
Optional Fan Configurations
The model chassis is designed so that the default configuration of the system
is for each serverboard to control two fans (Figure 3-10). The fans are hot-swappable. Each
serverboard node in the chassis is connected to the backplane through the adapter card,
mounted in the serverboard drawer. In the event that one of the serverboard drawers is
removed, then the remaining serverboard will operate both fans.
Fan Configurations Options
Hot-Swappable Default Configuration
Fan A connected to backplane, backplane connected to Node A by
adapter card
Fan B connected to backplane, backplane connected to Node B by
adapter card
Fan C connected to backplane, backplane connected to Node C by
adapter card
Fan D connected to backplane, backplane connected to Node D by
adapter card
Installing Fans
Fan speed is controlled by system temperature via IPMI. If a fan fails, the remaining fans
will ramp up to full speed. Replace any failed fan at your earliest convenience with the same
type and model (the system can continue to run with a failed fan).
