CAUTION: When handling modules, use an antistatic wrist strap connected
to the router's ESD grounding jack, and hold modules by their edges. Do not
touch the components, pins, leads, or solder connections. These actions help
to protect modules from damage by electrostatic discharge.
Before you install the new memory, issue the show hardware command to see how
much memory is installed. Each ERX7xx and ERX14xx model SRP module usually has at
least 256 MB of memory. You need one upgrade kit for each SRP module in the system.
Depending on the upgrade you are performing, the kit contains a specific number of
SODIMMs.
After removing the SRP module from the router, you might have to remove lower-memory
SODIMMs to upgrade to a higher-capacity SRP module. The SODIMM sockets are close
to the NVS card and have a cream-colored ceramic connector at one edge. Some or all
of the sockets might already contain SODIMMs.
Push down on the back edge of a SODIMM to release it from the socket. (See Figure
1.
38 on page 84.)
Gently pull the SODIMM up and out to disconnect it from the connectors and remove

it from the socket.
