Install a system board

Install a system board by inserting it in the compute tray, pushing it in until it locks in place, and connecting the cables.

CAUTION

The power-control button on the device and the power switch on the power supply do not turn off the electrical current supplied to the device. The device also might have more than one power cord. To remove all electrical current from the device, ensure that all power cords are disconnected from the power source.

CAUTION

Make sure that all server power cords are disconnected from their power sources before performing this procedure.

Before you install a system board, if you are replacing the system board as part of a maintenance operation, reinstall all of the following components that were removed from the original system board:

• Processor (see Processor and heat sink replacement)

• Memory modules and memory module fillers (see Memory module replacement)

• Memory air baffles (see Memory air baffle replacement)

• Cables (see Internal cable routing.)

If you are installing the lower system board in a compute tray, first remove the upper system board or filler from the compute tray to access connectors on the lower system board. See Remove a system board or Remove a system board filler.

Complete the following steps to install the compute system board:

Figure 1. System board installation

1. Align the system board with the rails in the compute tray; then, insert the system board, making sure that the rails on the board fit into the slots in the compute tray.
2. Slide the system board into the compute tray until the release clips snap into the locked position.
3. Connect all cables on the system board that go to connectors in the compute tray. See Internal cable routing.
