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 electrical outlets and turn them on.

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 System Setup, and check the value for System Memory.

The system should have already changed the value of System Memory to reflect the newly installed memory. Verify the new total. If it is

correct, skip to step 9.

8. If the memory total is incorrect, turn off and disconnect your computer and peripherals from their electrical outlets. Remove the computer

cover, rotate the power supply, and check the installed RIMMs to make sure that they are seated properly in their sockets. Then repeat steps

4, 5, 6, and 7.

9. Reset the chassis intrusion detector by selecting System Security and changing Chassis Intrusion to Enabled or Enabled-Silent.

10. When the System Memory total is correct, press <Esc> to exit System Setup.

11. Run the Dell Diagnostics to verify that the RIMMs are operating properly.

Removing Modules

NOTICE: Before you upgrade the RIMMs, you must perform the steps under BIOS Recovery Utility.

To remove a module (RCM or RIMM), press the securing clips outward simultaneously until the module disengages and pops out slightly from the

socket (see Figure 3). If you remove an RCM or RIMM, you must install another RCM or RIMM in the empty socket before turning on the computer.

Figure 3. Removing a Module

NOTE: The system supports no more than a total of 32 memory devices on all installed RIMMs. See Figure 1 for the location of a label

on the RIMM that identifies the number of memory devices it contains. You can also determine the number of memory devices

installed through the System Memory option in System Setup.

NOTE: After you remove and replace the cover, the chassis intrusion detector causes the following message to appear on the

screen at the next system start-up:

ALERT! Cover was previously removed.

NOTE: If a setup password has been assigned by someone else, contact your network administrator for information on resetting

the chassis intrusion detector.
