Remove the failed unit according to the server manufacturer instructions and install the replacement unit securely in the power bay. Reconnect power and monitor the server’s management interface or LED indicators to confirm that the new power supply is functioning correctly.

Use original or certified compatible parts (MPN 03KK326-RFB) and follow Lenovo ThinkSystem service documentation for installation, safety precautions, and disposal of defective units.
