HP XW3400 manual Memory

Memory

CAUTION: The memory module sockets have gold metal contacts. When upgrading the memory, it is important to use memory modules with gold metal contacts to prevent corrosion and/or oxidation resulting from having incompatible metals in contact with each other.

Static electricity can damage the electronic components of the workstation or optional cards. Before beginning these procedures, ensure that you are discharged of static electricity by briefly touching a grounded metal object. Refer to Electrostatic discharge information on page 52 for more information.

When handling a memory module, be careful not to touch any of the contacts. Doing so may damage the module.

1. Prepare the workstation for disassembly (Preparation for disassembly on page 59).

2. Remove the access panel and rotate the workstation so the system board is parallel to the table to make it easier to work on (Access panel on page 61).

WARNING! To reduce risk of personal injury from hot surfaces, allow the internal system components to cool before touching.

3. Open both latches of the memory module socket (1), and insert the memory module into the socket

(2). Refer to the Memory on page 165 appendix for the correct sequence for installing memory modules to get optimal performance.

NOTE: A memory module can be installed in only one way. Match the notch on the module with the tab on the memory socket. It may be easier to install a memory module in some cases if the main power cable from the power supply to the system board is temporarily disconnected. The workstation automatically recognizes the additional memory when the workstation is turned on.

4. Push the module down into the socket, ensuring that the module is fully inserted and properly seated. Make sure the latches are in the closed position (3).

To reassemble the workstation, reverse the removal procedure.
