Follow the procedure below to install the DIMM. Make sure to power off the server before starting installation except when replacing DIMM.

1.Shutdown OS.

The system turns off automatically.

2.Disconnect power cord from outlet.

3.Remove the CPU module.

4.Check to be sure in which socket you are mounting the DIMM.

IMPORTANT: Carefully keep the removed DIMM connector cover.

6.Insert a DIMM into the DIMM socket straight.

TIPS: Pay attention to the orientation of the DIMM. The terminal of the DIMM has a cutout to prevent misinsertion.

After the DIMM is completely inserted into the socket, the levers are automatically closed.
