Installation Guidelines

Some computers are equipped with an Advanced Memory Protection feature that enables the addition or replacement of memory while the computer is running. If your computer is equipped with this feature, see the documentation supplied with the computer for memory installation, replacement, and configuration procedures.

IMPORTANT: This computer may not support mixing RDIMMs and UDIMMs. Attempting to mix these two types can cause the computer to halt during BIOS initialization. For more information, see the computer product documentation.

Installing a DIMM

WARNING: Turn off the computer and disconnect the power cord from the computer before installing the DIMM. Failure to do so can damage the equipment and expose you to the risk of electric shock. To reduce the risk of personal injury, allow the DIMMs to cool before removing them.

WARNING: Always comply with all electrostatic and thermal guidelines to prevent bodily injury and ensure a properly functioning system when performing hot-plug operations.

1.Back up all data, power down the computer, and then disconnect the computer from all electrical outlets.

2.Access the DIMM slots. See the computer-specific documentation.

Use a nonmagnetic-tip screwdriver to remove any screws.

3.Open the DIMM slot latches.

CAUTION: DIMMs are keyed for proper alignment. Align notches in the DIMM with the corresponding notches in the DIMM slot before inserting the DIMM. Do not force the DIMM into the slot.

4.Insert the DIMM, applying equal pressure on both ends until the latches click into place.

If the latches do not click into place, press them inward to secure the DIMM in the slot.

5.Install all components removed to access the DIMM slots.

6.Connect the computer to an electrical outlet.

7.Power up the computer.

The installation is complete.
