Replacing Fan Units on MHO-200

About Fans

The Maestro Orchestrators are equipped with four replaceable fan units. They can fully operate, if one fan unit failed.

Important:
  • It is not supported to operate a Orchestrator, if two or more fan units failed.

  • Make sure that the fans have the air flow that matches the model number.

    An air flow opposite to the Orchestrator design causes the Orchestrator to operate at a higher (less than optimal) temperature. See Airflow in MHO-200.

Removing a Fan Unit

  1. Grasp and hold the fan unit's handle with your hand.

  2. Push the latch release with your thumb.

  3. Pull out the fan unit from the Orchestrator.

    As you pull out the fan unit, its status LED turns off.

Installing a Fan Unit

  1. Make sure the mating connector of the new fan unit is free of any dirt and obstacles.

  2. Insert the fan unit end into the opening.

  3. Slide in the fan unit until you feel a slight resistance.

  4. Continue to press the fan unit until it seats completely.

    The fan unit latch snaps into place. This confirms the proper installation.

  5. These LEDs must light up in the green color:

    1. The LED on the fan unit.

    2. The Fan Status LED (see Fan Status LED).

    If either of these LEDs does not light up in the green color, repeat the whole procedure to remove the fan unit and insert it again.

    After two unsuccessful attempts to install the fan unit, power off the Orchestrator before you attempt any hardware troubleshooting.
