Upgrading Memory on SRP Modules

This section describes how to upgrade memory on SRP modules. E-series
software releases 3.0.x and higher require at least 512 MB of memory on
each SRP module, while releases 5.3.x and higher require at least 1 GB of
memory. See E-series Module Guide for more information.
NOTE: The ERX-310 SRP module contains two SODIMM banks that use 256-MB
memory, and currently is not upgradeable.
Four main steps are involved in upgrading memory on SRP modules:
1.
2.
3.
4.
See the following sections for information on each step.
WARNING: Do not insert any metal object, such as a screwdriver, or place your
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.
CAUTION: When handling modules, use an antistatic wrist strap connected to the
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.
