Fan modules
The server must be configured with six hot swappable fan modules, each of which includes two
fans. Figure 11-11 sh
ows the layout of the fan modules in the chassis.
The fans support N+1 redundancy.
During system POST and operation, the server will be powered off through HDM if the temperature
detected by any sensor in the server reaches the critical threshold. The server will be powered off
directly if any key components such as processors exceed the upper threshold.
