Lenovo ThinkSystem ST250 V2 Maintenance Manual page 191

The following tips describe the type of power supply that the server supports and other information that you
must consider when you install a 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 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.

the server, go to:

Attention:
• Read the "Installation guidelines" on page 85 to ensure that you work safely.
• Touch the static-protective package that contains the component to any unpainted metal surface on the
server; then, remove it from the package and place it on a static-protective surface.
