Replacing Power Supply Units
Quantum Maestro Orchestrators are equipped with two replaceable Power Supply Units (PSUs). The PSUs
in these systems can work in a redundant configuration. It is possible to remove one of the PSUs without the
need to bring down the Quantum Maestro Orchestrator.
Important - PSUs have directional air flows similar to the fan module. The fan module
airflow must coincide with the airflow of all of the PSUs. If the PSU airflow direction is
different from the fan module airflow direction, it affects the Quantum Maestro
Orchestrator's internal temperature.

1. The System Status LED is lit in steady green (see "System Status
LED" on page32 ).
2. The Power Supply Unit Status LEDs on the PSU that you leave in the
Orchestrator are lit in steady green (see "Power Supply Unit Status
LEDs" on page36 ).

To ensure proper cooling, do not leave the PSU slots of a Quantum Maestro
Orchestrator empty for more than five minutes.
