Figure 73. Hot-swap power supply removal
After you finish
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 135.
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.

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:
https://datacentersupport.lenovo.com/solutions/lnvo-lcp
– Ensure that the devices that you are installing are supported. For a list of supported optional devices for
the server, go to:
