After removing the power supply:
• Install a power supply filler or a new power supply to cover the power supply bay.
Important:
To ensure proper cooling during normal server operation, both of the power supply bays must

installed and the other has a power supply filler installed.
• If you are instructed to return the old power supply, follow all packaging instructions and use any
packaging materials that are provided.
