Installing a DIMM
You can install a DIMM to increase the amount of dynamic random-access
memory (DRAM) in the router.
Follow these steps to install a DIMM on the router motherboard:
Step 1
Locate the DIMM slot on the motherboard.
Step 2
Remove any existing DIMM by pulling the DIMM slot guides (shown in
Figure C-3
) away from the DIMM and down toward the motherboard.

Step 3
Insert the DIMM into the DIMM slot, making sure that the notches on the edge of
the DIMM are inserted over the bars inside the DIMM slot, as in
Figure C-3
.
Step 4
Firmly press the DIMM into the slot until the two DIMM slot guides on each side
of the slot move up and over the end of the DIMM, as in
Figure C-3
. If the guides
do not move up over the edge of the DIMM, move them with your hands.
