Installing a SODIMM
You can install a SODIMM to increase the amount of DRAM in the router.
To install a SODIMM on the router motherboard, follow these steps:
Step 1 Locate the SODIMM socket on the motherboard.
Step 2 Remove any existing SODIMM by gently pulling the spring-loaded clips on the end of the socket far
enough to clear the SODIMM, and gently pulling the SODIMM up and away from the socket. See
Figure 8-5.
