Installing the 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: Many repairs may only be done by a certified service technician. You 
should only perform troubleshooting and simple repairs as authorized in your 
product documentation, or as directed by the online or telephone service and 
support team. Damage due to servicing that is not authorized by Dell is not 
covered by your warranty. Read and follow the safety instructions that came with 
the product. 
1  Press down and out on the ejectors on each end of the memory module 
socket. See Figure 3-59. 
2  Align the memory module correctly with the alignment key of the 
memory module socket. See Figure 3-59. 
3  Press down firmly on the memory module with your thumbs until the 
module snaps into place. See Figure 3-59. 
 
CAUTION: Even pressure during insertion must be applied at both ends of the 
module simultaneously to prevent damage to the socket. No pressure should be 
applied to the center of the module. 
Complete the latching of the module into the socket by applying 
inward pressure to the socket ejectors to assure that the ejectors are in 
a locked position. When the memory module is properly seated in the 
socket, the ejectors on the memory module socket align with the 
ejectors on other identical sockets that have memory modules installed.
