Fan Board Assembly

The cooling system supports either a non-redundant configuration or a redundant
configuration. A non-redundant configuration includes just three fans. If any one of these
three fans ceases to function normally, environmental conditions within the chassis may
exceed the environmental regulations in this guide and the chassis may not function
normally. Three fans support any system configuration but without fan redundancy.

The SGI 1450 server uses all six fans to form a redundant cooling system. If one of the six
fans ceases to function normally, the remaining five fans adequately cool the system.
Using six fans supports any configuration up to the maximum configuration.

Air flows in through the front bezel over the power subsystem bay, the peripheral bay,
and the hard drive bay. The air then passes through the fan board assembly and the
E-Bay. Finally, the air exhausts through the rear and left side of the chassis.

Individual fan status indicators are located on the fan board mounted in the fan board
assembly. Fan failure is also indicated by the general fault LED located at the front of the
chassis.
