How to install Cisco 650W AC Power Supply

  • Power down the Cisco chassis and disconnect all power sources to ensure a safe replacement procedure. Confirm that the device is fully powered off before proceeding with any hardware work.
  • Open the chassis access area according to the chassis manual and locate the PSU slot that matches the 650W port side intake module. Ensure you have the correct replacement unit for your model, as power supply compatibility is model-specific.
  • Align the new PSU with the chassis slot, making sure the connectors and mounting ears engage properly. Slide it into place gently but firmly until it seats fully into the backplane or power shelf as specified by the equipment manual.
  • Connect the AC input cable to the PSU and route the cable for clean cable management and unobstructed airflow. Secure the cable to prevent accidental disconnection or strain on the power connectors during operation.
  • Restore power to the chassis and monitor the power supply status indicators. Verify that the PSU is recognized by the chassis and that there are no fault indicators. If available, run a brief post-install diagnostic to confirm stable operation and proper cooling within the unit.
