Displaying The Memory Installed; Removing Sodimms; Adding New Sodimms - Juniper ERX - RELEASE 11.1.X HARDWARE GUIDE 03-23-2010 Hardware Manual

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.

Displaying the Memory Installed

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.

Removing 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.

Adding New SODIMMs

To add new SODIMMs:
Push down on the back edge of a SODIMM to release it from the socket. (See
Figure 38 on page 84.)
Gently pull the SODIMM up and out to disconnect it from the connectors and
remove it from the socket.
