1 About the R6900-FAN fan module
|
IMPORTANT: · The information in this document might differ from your product if it contains custom configuration options or features. · The model name of a hardware option in this document might differ slightly from its model name label. A model name label might add a prefix or suffix to the hardware-coded model name. For example, the R6900-FAN fan module model represents fan module labels including UN-R6900-FAN-S, which has a different prefix and suffix. |
The R6900-FAN fan module contains two fans. Each fan has a rotor composed of seven vanes at the air inlet and a rotor composed of five vanes at the air outlet. When a fan operates normally, the two rotors are reversed in direction to form counter-rotation for sufficient wind pressure. The R6900-FAN fan module is hot swappable, and provides fast heat dissipation and high speed.

2 Key features
Automatic speed adjustment
The fan uses pulse width modulation (PWM) to adjust fan speed quickly, accurately, and stably according to system instructions. If the external environment or a system internal component has a high temperature, the fan speed increases to help fast heat dissipation. If the temperature of the external environment drops, the fan speed decreases to save energy.
Hot swapping
The fan module is hot swappable, improving system maintainability.
Locked rotor protection
This feature protects the fan from being damaged for up to 96 hours if a rotor of a fan operating under normal voltage stops rotating due to a foreign object.
Polarity protection
If the polarity of the input voltage does not match the polarity of the fan, the fan cannot operate correctly but will not be damaged.
