OCPRF100 MP Server System Technical Product Specification

Revision 1.0

The fan bay will operate at high speed on the following conditions:

•Internal temperature has reached an elevated, but noncritical set-point.

•Ambient temperate exceeds 30°C.

•A fan has entered into the predictive failure mode.

•A fan has failed.

If the FPC detects a fan entering the predictive fan failure mode, the speed of all of the fans will be increased to maintain thermal requirements. The individual fans within the fan bay are all hot- swappable, meaning that they can be removed and inserted while the server is running. Server management will identify that a fan has either failed or has entered into the predictive failure mode. In both cases, the fan should be replaced immediately. Removal of a fan is accomplished by opening the fan bay cover and pulling (A) to lift the malfunctioning fan (B) out through the top of the server as shown in Figure 2-5: Fan Bay. The malfunctioning fan should then be replaced with a new fan. The system will detect that the fan has been replaced, and as long as no other thermal violations are currently occurring, the fan will resume operation at the reduced speed.
