Upgrading Memory on SRP Modules

This section describes how to upgrade memory on SRP modules. JUNOSe 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 the ERX Module Guide for more information.

Note: The ERX-310 SRP module contains two small outline dual inline memory module (SODIMM) banks that use 256-MB memory, and currently is not upgradeable.

Four main steps are involved in upgrading memory on SRP modules:

Display how much memory is currently installed on the SRP module.
Remove the SRP module and the SODIMMs.
Add the new SODIMMs to the SRP module.
Reinstall the SRP module and verify the upgrade.

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 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 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.
