Insert module vertically and press down until it snaps into place. Pay attention to the
alignment notch at the bottom.
2 FBD
To Remove
Use your thumbs to gently push the release tabs near both ends of the module. This should
release it from the slot.
NOTE : Due to memory allocation to system devices, memory remaining available for
operational use will be reduced when 4 GB of RAM is used. The reduction in
memory availability is disproportional. (Refer to the Memory Availability Table
below for details.)
