Checking The Memory Installed; Removing Sodimms; Adding New Sodimms - Juniper E Series Hardware Manual

Checking the Memory Installed

Before you install the new memory, issue the show hardware command
to check how much memory is installed. Each ERX-7xx/14xx model SRP
module should currently use at least 256 MB of memory. You will need
one upgrade kit for each SRP module in the system.
Depending on the upgrade you are performing, the kit will contain a specific
number of small outline dual inline memory modules (SODIMMs).

Removing SODIMMs

After removing the SRP module from the E-series router, you may 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 ceramic connector at
one edge. Some or all of the sockets may already contain SODIMMs.

Adding New SODIMMs

To add new SODIMMs:
1.
Push down on the back edge of a SODIMM to release it from the socket
(see Figure 41).
Gently pull up and out to disconnect the SODIMM from the connectors and
remove it from the socket.
Locate the four SODIMM sockets on the SRP module (see Figure 41 and
Figure 42). See the previous section to learn how to remove SODIMMs.
