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 ERX310 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:
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 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.
