Replacing Power Supply Units

Quantum Maestro Orchestrators A scalable Network Security System that connects multiple Check Point Security Appliances into a unified system. Synonyms: Orchestrator, Quantum Maestro Orchestrator, Maestro Hyperscale Orchestrator. Acronym: MHO. 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 See "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.

Removing a Power Supply Unit

Important:

Before you remove one of the PSUs, make sure that:
1. The System Status LED is lit in steady green (see System Status LED).
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).
To ensure proper cooling, do not leave the PSU slots of a Quantum Maestro Orchestrator empty for more than five minutes.

Installing a Power Supply Unit

Important - Do not insert a PSU with a power cord connected to it.

Step	Instructions
1	Make sure the mating connector of the new PSU is free of any dirt and obstacles.
2	Insert the PSU end into the opening.
3	Slide in the PSU until you feel a slight resistance.
4	Continue to press the PSU until it seats completely. The PSU latch snaps into place. This confirms the proper installation.
5	Connect the power cord to the PSU connector.
6	Insert the other end of the power cord into an outlet of the correct voltage.
7	These should light up in green color: The indicator on the PSU The Power Supply Unit Status LED (see Power Supply Unit Status LEDs) If either the indicator, or the LED does not light up in green color, repeat the whole procedure to remove the PSU and insert it again.
