the chassis correctly.

About this task
The following describes the information that you must consider when installing a power supply:
• The server is shipped with only one power supply by default. In this case, the power supply is non-hot-
swap and before removing it, you must turn off the server first. To support redundancy mode or hot-swap,
install an additional hot-swap power supply.
• If you are replacing the existing power supply with a new power supply:
– Use Lenovo Capacity Planner to calculate the required power capacity for what is configured for your
server. More information about Lenovo Capacity Planner is available at:
