CAUTION:CAUTION: To avoid damage to the equipment, do not operate the server for extended periods of time if the server does not
have the optimal number of fans installed. Although the server might boot, Hewlett Packard Enterprise does not
recommend operating the server without the required fans installed and operating.
The redundant fan option kit contains the redundant system and PCI fans. Mixed default and redundant fan configuration is not supported.
Redundant fan mode is required to meet the system thermal requirements under the following conditions:
Server with the following options installed:
SFF SAS 15K RPM hard disk drives
SFF 24G SAS-4 solid state drives
When SFF 24G SAS-4 SSDs are installed, the operating inlet ambient system temperature is 25°C (77°F).
HPE NS204i-u Boot Device
Passive graphics accelerator
35°C (95 °F) to 45°C (113°F) ambient system temperature

Fan mode behaviorFan mode behavior
In redundant fan mode:
A fan rotor failure will switch the system to nonredundant fan mode.
This change is indicated by the Health LED flashing amber. The system continues to operate normally in this mode.
A second fan rotor failure or a missing fan causes the operating system to orderly shutdown.
In nonredundant fan mode, a fan rotor failure or a missing fan causes:
The system Health LED to flash red.
The operating system to orderly shutdown.
