Procedure
1. Ensure that all power supplies (power supply units) for the enclosures (controller node enclosure and
drive enclosure) have a solid-green status LED indicating a normal operation state.
• Review Power supply unit LEDs, controller node enclosure on page 82 .
• Review Power supply unit LEDs, drive enclosure on page 83 .
2. Turn off the power source at the panel that provides input power to one PDU. Alternatively, the circuit
breaker(s) on the PDU can be set to the OFF position.
For example, as represented in Figure 21: Redundant power configuration on page 35:
• When Customer power source A1 is turned off, the power supplies connected to PDU-0 turn off.
• When Customer power source B2 is turned off, the power supplies connected to PDU-3 turn off.
3. Ensure that the following expected behavior has occurred:
• Every enclosure: At least one power supply is operating normally.
• Every power supply without input power: The LEDs turn off.
4. After confirmation of the expected behavior, turn back on the power source at the panel for the PDU
and wait 30-60 seconds.
5. Before moving to the next PDU, ensure that the green status LED is illuminated on all components.
6. For each PDU, repeat the prior steps.
