how to install Supermicro PWS-1K03A-1R Power Module

• Power down the server and unplug the power cord from the outlet to ensure a safe working environment before handling any internal components.
• Open the chassis access panel and locate the dedicated power-module bay within the backplane area. Identify the slot that corresponds to the PWS-1K03A-1R, ensuring no obstructions or cables will interfere with installation.
• If replacing an existing module, remove the existing unit by disengaging the retention latch and carefully pulling it straight out of the bay. Take care not to damage connectors or surrounding components.
• Orient the PWS-1K03A-1R so that its connectors align with the backplane interface. Slide the module into the bay with even pressure until the module is fully seated and the retention latch engages securely.
• Reconnect any cables or connectors that were detached during the removal process, reseal the chassis, and restore power. Once powered, use the system management tools or LED indicators on the module to verify operational status and confirm full integration with the backplane.
