How to Install Supermicro PWS-1K02A-1R

• Power down the host system and unplug all power cords. Ground yourself to prevent static discharge and follow your data-center safety procedures.
• Open the chassis and locate the PSU slot designated for the redundant power supply. If replacing an existing unit, disconnect its cables and carefully remove it according to the server manual.
• Align the PWS-1K02A-1R with the slot’s mounting rails and the card edge connector. Gently slide the unit into position until the connector seats firmly and the mounting points align with the chassis.
• Secure the PSU with the supplied mounting screws. Double-check that the unit is seated squarely and that there is adequate clearance for airflow around the power supply.
• Reconnect the power pathway as required by your server backplane or system design. Ensure the card edge interface is properly mated to the backplane, and verify any redundant connections per the system’s maintenance guide.
• Reassemble the chassis, restore power, and power on the system. Use the server management interface or BIOS to verify the PSU is detected, that redundancy is functional, and that the power rails are delivering stable voltages under load.
