Install a hot-swap power supply
Use this information to install a hot-swap power supply.
The standard shipping has only one power supply installed in the server. For redundancy and hot-swap support, you must install an additional hot-swap power supply. Certain customized models might be shipped with two power supplies installed.
Ensure that the devices that you are installing are supported. For a list of supported optional devices for the server, go to: Lenovo ServerProven website
Ensure that the two power supplies installed on the server have the same wattage.
If you are replacing the existing power supply with a new power supply of different wattage, attach the power information label that comes with this option onto the existing label near the power supply.

Before installing a hot-swap power supply, touch the static-protective package that contains the new hot-swap power supply to any unpainted surface on the outside of the server. Then, take the new hot-swap power supply out of the package and place it on a static-protective surface.
To install a hot-swap power supply, complete the following steps:
- If the server is in a rack, adjust the cable management arm (CMA) to gain access to the power supply bay.
If you have installed the 2U CMA Upgrade Kit for Toolless Slide Rail or Toolless Slide Rail Kit with 2U CMA, do the following:
Figure 2. CMA adjustment
- Press down the stop bracket 1 and rotate it to the open position.
- Rotate the CMA out of the way to gain access to the power supply bay.
- If there is a power-supply filler installed, remove it.Figure 3. Hot-swap power supply filler removal
- Slide the new hot-swap power supply into the bay until it snaps into position.Figure 4. Hot-swap power supply installation
Connect one end of the power cord to the new power supply connector; then, connect the other end of the power cord into a properly grounded electrical outlet.
If the server is turned off, turn on the server. Ensure that both the power input LED and the power output LED on the power supply are lit, indicating that the power supply is operating properly.
