2.To access the memory module sockets on the system board, rotate the power supply as described in “Rotating the Power Supply Away From the System Board” in Chapter 7.
3.Determine the memory module sockets in which you will install memory mod- ules or replace existing memory modules.
4.Install or replace memory modules as necessary to reach the desired memory total.
Follow the instructions in “Installing a Memory Module” or “Removing a Mem- ory Module,” later in this chapter as appropriate.
5.Rotate the power supply back into position, making sure that the securing tab snaps into place.
6.Replace the computer cover, and reconnect your computer and peripherals to their power sources and turn them on.
NOTE: After you remove and replace the cover, the chassis intrusion detector will cause the following message to be displayed at the next system
ALERT! Cover was previously removed.
The system detects that the new memory does not match the existing system configuration information and generates the following message:
The amount of system memory has changed.
Strike the F1 key to continue, F2 to run the setup utility
7.Press <F2> to enter the System Setup program, and check the value for system memory.
The system should have already updated the value of system memory to reflect the newly installed memory. Verify the new total.
NOTE: If the memory total is incorrect, turn off and disconnect your computer and peripherals from their power sources. Remove the computer cover, rotate the power supply, and check the installed memory modules to make sure that they are seated properly in their sockets. Then repeat steps 5, 6, and 7.
8.While in the System Setup program, reset the chassis intrusion detector. See your User's Guide for instructions on using the System Setup program.
NOTE: If a setup password has been assigned by someone else, contact your network administrator for information on resetting the chassis intrusion detector.
9.When the system memory total is correct, press the <Esc> key to exit the Sys- tem Setup program.
10.Run the Dell Diagnostics to verify that the memory modules are operating properly.
