Fans
HP POD 20c fans operate at variable speeds to maintain the following setpoints programmed in the ECS. The
setpoints are maintained in the following order:

2. Hot aisle temperature setpoint
The fan speed adjusts to maintain both setpoints. Do not manually adjust the fan speed.
IMPORTANT: HP recommends leaving the fans in AUTO mode during normal operation.
