Installing A Dimm; Figure 7-6. Installing A Dimm - Dell 2200 User Manual

The system detects that the new memory does not
match the system configuration information, which
is stored in nonvolatile random-access memory
(NVRAM), and generates the following error
message:
System memory size has changed — Run
Configuration Utility
Press F1 to resume, F2 to Setup
7. Press <F2> (when prompted while the computer
is booting) to enter the System Setup program,
and check the Extended Memory category on the
main menu of the System Setup screens.
The system should have already changed the value
of the Extended Memory category to reflect the newly
installed memory. Verify the new total.
NOTE: If the memory total is incorrect, turn off your
computer and peripherals and disconnect them from
their power sources. Remove the computer cover and
system board, and check all the installed DIMMs to
make sure they are seated properly in their sockets.
Then repeat steps 6 and 7.
8. Enter the EISA Configuration Utility. Then save
the configuration and exit the utility.
Running the EISA Configuration Utility and saving
the configuration is required for the system to recog-
nize the newly installed DIMMs. See Chapter 5,
"Using the EISA Configuration Utility," for instruc-
tions on running the utility and saving the
configuration.
NOTE: In the EISA Configuration Utility, the value
of Extended Memory is specified in kilobytes. To convert
megabytes to kilobytes, multiply the megabyte value by
1024.
9. When the Extended Memory total is correct, run
the diskette-based diagnostics to test all installed
DIMMs.
See Chapter 2, "Using the Dell Server Assistant
CD," for information on running the diagnostics
from the Dell Server Assistant CD. See the chapter
titled "Running the Diskette-Based Diagnostics" in
your Diagnostics and Troubleshooting Guide for infor-
mation on the memory diagnostics.

Installing a DIMM

NOTE: The following procedure assumes that the system
board assembly has been removed from the computer and
is laying on a flat work surface. See "Removing and
Replacing the System Board Assembly" in Chapter 6.
Install DIMMs starting with socket DIMM_A, located
nearest the PCI expansion-card connector, and working
toward socket DIMM_D, nearest the center of the system
board. If a DIMM is already installed in the socket you
need, you must remove it. Follow the instructions in the
next subsection, "Removing a DIMM," if appropriate.)
Use the following procedure to install a DIMM:
1. Press the ejectors on the DIMM socket down and
outward, as shown in Figure 7-6, to allow the
DIMM to be inserted in the socket.
2. Align the DIMM's edge connector with the slot in
the center of the DIMM socket, and insert the
DIMM in the socket.
The card-edge connector on the DIMM is keyed so
that the DIMM can only be installed in the socket in
one way (Figure 7-6).
3. Press down on the two outer edges of the DIMM
with your thumbs while pulling up on the ejectors
with your index fingers to lock the DIMM into the
socket.
When the DIMM is properly seated in the socket, the
ejectors on the DIMM socket should align with the
ejectors on the other DIMM sockets.
