Do not insert any metal object, such as a screwdriver, or place your
WARNING:
hand into an open slot or the backplane when the E-series router is on. Remove
jewelry (including rings, necklaces, and watches) before working on equipment
that is connected to power lines. These actions prevent electric shock and serious
burns.
When handling modules, use an antistatic wrist strap connected to the
CAUTION:
E-series 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 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).
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.
1. Push down on the back edge of a SODIMM to release it from the socket (see
Figure 43).
2. Gently pull up and out to disconnect the SODIMM from the connectors and
remove it from the socket.
1. Locate the four SODIMM sockets on the SRP module (see Figure 43 and
Figure 44). See the previous section to learn how to remove SODIMMs.
