To install a memory module, complete the following steps:
1. Prepare the computer for disassembly (Section 4.2).
WARNING: Power is continuous to the system board and power supply even when the power
switch is turned off. To prevent damage to the unit, disconnect the power cord from the power
source or the unit before beginning disassembly procedures.
2. Remove the computer cover (Section 4.3).
3. Open both latches of the memory socket 1, and insert the memory module into the
socket 2.
4. A memory module can be installed in only one way. Match the notch on the module
with the tab on the memory socket. Push the module down into the socket, ensuring
the module is securely seated. Close both latches 3.
5. Repeat steps 3 and 4 for any additional modules you want to install.
6. Reassemble the computer.
7. Turn on the computer.
When a memory module has been removed, moved, or added, Memory Change
Alerts, a feature of Intelligent Manageability, alerts the system administrator and
end user. The system automatically recognizes the added memory.
