In a single-processor system, nonredundant configuration, fans 2–4 are preinstalled in the fan cage and a fan blank is preinstalled in bay
1.
In a dual-processor system, nonredundant configuration requires a fan in bay 1.
To enable redundant fan mode in single- and dual-processor systems, install fans in bay 1, 5–8.
In the E3.S drive configuration, the external fan 10 is default in the server.
When installing high power accelerator options in the primary and secondary risers, external fans 9–10 covering the rear side of riser
slots are highly recommended.
To maintain optimum system cooling, observe the following fan requirements for specific hardware components:

For additional cooling support, Hewlett Packard Enterprise highly recommends installing an external fan.
