System Memory Upgrade

After you replace the cover, if the chassis intrusion option is set to Enabled, the

chassis intrusion detector causes the following message to be displayed at the

next system start-up:

ALERT! Cover was previously removed.

Enter system setup. When Setup appears in the upper-right corner of the

screen, press <F2>.

If you wait too long and the operating system begins to load into memory, allow

the system to complete the load operation; shut down the system and try again.

NOTE: For instructions on using system setup, see the User's Guide.

10. Reset the Chassis Intrusion option:

Press the down-arrow key to move to the System Security option.

Press <Enter> to access the System Security option's pop-up menu.

Press the down-arrow key to move to the Chassis Intrusion option.

Press the left- or right-arrow key to select Reset.

Choose Enabled, Enabled-Silent, or Disabled.

NOTES: The chassis intrusion default is Enabled.

If a setup password has been assigned by someone else, contact the network

administrator for information on resetting the chassis intrusion detector.

See the system User's Guide for information on the chassis intrusion detector.

11. When the memory total is correct, press <Esc> to exit system setup.

If the memory total is incorrect, repeat steps 2 through 4. Check the installed

modules to ensure that they are seated properly in their sockets. Then repeat

steps 5 through 10.

If the memory total is still incorrect, contact Dell for technical support.

See "Getting Help" in the User's Guide.
