Removing a hot-swap power supply
Important: If the server has two power supplies and if you remove either of them,
the server will not have redundant power; if the server power load then exceeds
835 W, the server might not start or might not function correctly.
To remove a power supply, complete the following steps.
Release lever
1. Read the safety information that begins on page vii and “Installation guidelines”
on page 105.
2. If only one power supply is installed, turn off the server and all attached
devices.
3. Disconnect the power cord from the power supply you are removing.
4. Grasp the power-supply handle.
5. Press the orange release latch down and hold it down.
6. Pull the power supply part of the way out of the bay.
7. Release the release latch; then, support the power supply and pull it the rest of
the way out of the bay.
8. If you are not installing a replacement power supply, install the power supply
filler panel.
9. If you are instructed to return the power supply, follow all packaging instructions,
and use any packaging materials for shipping that are supplied to you.
Note: It is not necessary to remove any fans when you remove a power supply.
You must, however, have all 10 fans installed when you have both power supplies
installed.
