how to install Lenovo System x 750W High Efficiency -48 V DC Power Supply

• Power down and isolate the server according to your data-center procedures. Disconnect all power sources and ground yourself to prevent static discharge.
• Access the PSU bay in the Lenovo System x chassis. If the chassis supports tool-free access, use the designated latch or release mechanism to open the bay for the replacement module.
• Remove the existing module if replacing an old unit. Align the new 750 W -48 V DC power supply with the bay rails and slide it firmly into place until the latch engages or the connector seats completely.
• Connect the -48 V DC input cables from your distribution unit or DC power source to the new power supply. Ensure cables are fully seated and neatly routed to maintain airflow and reduce cable strain on the connector.
• Secure the power supply in the bay, reclose the chassis, and restore power. Power on the server and verify that the new PSU is detected by the system management software or hardware indicators. Confirm green status indicators and verify that power delivery is stable under load conditions.
