* PSU 2 in the right PDUs: Connect PSU 2 to one of the PDUs on the right side of the rack. This ensures that PSU 2 is powered by the second power source.
* Ensuring Redundancy:
* By placing PSU 1 on the left and PSU 2 on the right, you create a redundant power configuration.
If either power source fails, the other PSU can continue to supply power to the server, maintaining its operation.
* Steps for Connection:
* Step 1: Verify that the rack's PDUs are correctly connected to their respective power sources.
* Step 2: Identify the left and right PDUs based on their power source connections.
* Step 3: Connect PSU 1 to a PDU on the left side of the rack.
* Step 4: Connect PSU 2 to a PDU on the right side of the rack.
* Step 5: Confirm that both PSUs are securely connected and receiving power from separate sources.
* Safety and Verification:
* Ensure that all connections are secure and that the cables are managed to prevent interference with other components or airflow within the rack. Verify that each PSU is functioning correctly by checking the server's power status indicators.
