Figure 136. 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
power supply unit” on page 174
.
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 component or optional device, follow all packaging instructions, and
use any packaging materials for shipping that are supplied to you.

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:

– Attach the power information label that comes with this option onto the existing label near the power
supply.
