Install a memory module

Memory modules are in the system boards that are accessed from the front of the server.

S002

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.

See Memory module installation rules and order for detailed information about memory configuration and setup.

CAUTION

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

Note

The same procedure is used to install memory modules and memory module fillers.

Complete the following steps to install a memory module:

1. Install the memory module.
   Figure 2. Memory module installation
   
   
   1. Open the memory module connector retaining clips. If a memory module is already installed in the connector, remove it.
   2. Align the keys on the memory module that you are installing with the connector; then, insert the memory module.
   3. Firmly press both ends of the memory module straight down into the connector until the retaining clips snap into the locked position.
2. If you are installing additional memory modules, do so now.
