130 Installing System Components
11
Install the expansion card stabilizer. See "Installing the Expansion Card 
Stabilizer."
12
Close the system. See "Closing the System."
13
Place the system upright and on its feet on a flat, stable surface.
14
Reattach any peripherals, then connect the system to the electrical outlet.
15
Turn on the system and attached peripherals.
16
Press <F2> to enter the System Setup program, and check the 
System 
Memory
 setting on the main System Setup screen.
The system should have already changed the value to reflect the newly 
installed memory.
17
If the value is incorrect, one or more of the memory modules may not be 
installed properly. Repeat step 5 through step 8 of this procedure, checking 
to ensure that the memory modules are firmly seated in their sockets.
18
Run the system memory test in the system diagnostics. See "Running the 
System Diagnostics."
Removing Memory Modules
  WARNING: The memory modules are hot to the touch for some time after the 
system has been powered down. Allow time for the memory modules to cool 
before handling them. Handle the memory modules by the card edges and avoid 
touching the components on the memory module.
 
CAUTION: To ensure proper system cooling, memory-module blanks must be 
installed in any memory socket that is not occupied. Install a memory-module 
blank if you are removing a memory module and do not intend to install a 
replacement.
1
Turn off the system, including any attached peripherals, and disconnect 
the system from the electrical outlet and peripherals.
2
Open the system. See "Opening the System."
3
Remove the expansion card stabilizer. See "Removing the Expansion Card 
Stabilizer."
4
Remove the cooling shroud. See "Removing the Cooling Shroud."
5
Locate the memory module sockets. See Figure 6-1.
