Removing a hot-swap power supply

Attention: The information in this document regarding installing and removing power supplies and connecting and disconnecting power refers to ac power supplies only. If the server contains dc power supplies, see the documentation that comes with the dc power supplies. In a dc power environment, only trained service personnel other than Lenovo service technicians are authorized to connect or disconnect power to the dc power supply and to install and remove a dc power supply.

Important: If the server has two power supplies and 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:

1.If only one power supply is installed, turn off the server and peripheral devices.

2.Disconnect the power cord from the power supply that you are removing.

3.Grasp the power-supply handle.

4.Press the orange release latch down and hold it down.

5.Pull the power supply part of the way out of the bay.

6.Release the release latch; then, support the power supply and pull it the rest of the way out of the bay.

If you have other optional devices to install or remove, do so now. Otherwise, go to “Completing the installation” on page 74.

Installing a fan

For proper cooling, the server requires that five fans be installed for each power supply installed.

The server comes with five replaceable fans. If you install a second power supply, you must install the set of five fans that come with the power-supply.

Important: Only the configurations that are shown in the following table are supported. The fan numbers are printed on the microprocessor air baffle.
