Fan Speed Adjustment
Set the fan speed adjustment mode to "automatic" or "manual" in the command line interface
(CLI). After the fans are installed, they work in automatic mode by default.
l Automatic mode
– Control-system-triggering: The control system automatically adjusts fan speed
according to the board temperatures for energy conservation.
– Monitoring-board-triggering: The speed is automatically adjusted based on the
temperature which is detected by a temperature sensor.
NOTE
The automatic mode has two variants (automatically selected by the system): control-system-
triggering and monitoring-board-triggering.
l Manual mode
Commands are executed to adjust fan speed. The levels range from 0 to 6, level 0 being
the lowest speed and level 6 being the highest speed.
