Fans

IT cooling fan

HP POD 20c fans operate at four speeds to maintain the cold-to-hot aisle differential pressure and hot aisle temperature setpoints that are programmed into the ECS.

The fan speed adjusts to maintain the programmed setpoints. Do not manually adjust the fan speed.

CAUTION: Power must be removed from the fan power assembly before removing or replacing a fan or fan bank.

CAUTION: De-energize any additional working fans within the affected zone before replacing the fan. De-energizing working fans reduces the IT cooling airflow within the zone. Take this into consideration when deciding whether to continue operating IT equipment within the affected zone. HP recommends powering down all of the IT in the zone.

IMPORTANT: HP recommends leaving the fans in AUTO mode during normal operation.
