After removing the hot-swap power supply:
1. Install a new power supply or install the power-supply filler to cover the power supply bay. See "Install a
hot-swap power supply" on page 55.
Important: To ensure proper cooling during normal server operation, both of the power supply bays
must be occupied. This means that each bay must have a power supply installed; or one has a power
supply installed and the other has a power supply filler installed.
2. If you are instructed to return the old hot-swap power supply, follow all packaging instructions and use
any packaging materials that are provided.
