Replacing Fan Units
The Quantum Maestro Orchestrators are equipped with four replaceable fan units. They can fully operate, if
one fan unit failed.
Important:
n
It is not supported to operate a Quantum Maestro Orchestrator, if two or more fan
units failed.

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

Quantum Maestro Orchestrator to operate at a higher (less than optimal)
temperature.
