Attention: 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. See the documentation that comes with each dc power supply for installation instructions.

1.Read the safety information that begins on page v and “Installation guidelines” on page 29.

2.Remove the power-supply filler panel from the empty power-supply bay by pinching the side clip and pulling the power-supply filler panel from the bay. Save the power-supply filler panel in case you remove the power supply at a later time.

Important: During normal operation, each power-supply bay must contain either a power supply or power-supply filler panel for proper cooling.

3.Slide the ac power supply into the bay until the retention latch clicks into place.

4.Remove the server cover and install the five cooling fans that came with the power-supply (see “Installing a fan” on page 68).

Important: When power supply 1 is installed, the five fans for power supply 1 occupy the rear row only (fans 3, 4, 8, 9, and 10); when both power supplies are installed, all 10 fans must be installed. See the fan numbers on the microprocessor air baffle, or see the illustration in “Removing a fan” on page 69.

5.Connect the power cord for the new ac power supply to the power-cord connector on the power supply.

The following illustration shows the ac power-supply connectors on the back of the server.

6.Route the power cord through the power-supply handle and through any cable clamps on the rear of the server to prevent the power cord from being accidentally pulled out when you slide the server in and out of the rack.

7.Connect the power cord to a properly grounded electrical outlet.

8.Make sure that the dc power LED and ac power LED on the power supply are lit, indicating that the power supply is operating correctly.

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