Maintaining ERX Routers
Four main steps are involved in upgrading memory on SRP modules:
1.Display how much memory is currently installed on the SRP module.
2.Remove the SRP module and the SODIMMs.
3.Add the new SODIMMs to the SRP module.
4.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.
Displaying the Memory Installed
Before you install the new memory, issue the show hardware command to see how much memory is installed. Each
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
1.Push down on the back edge of a SODIMM to release it from the socket. (See Figure 38.)
2.Gently pull the SODIMM up and out to disconnect it from the connectors and remove it from the socket.
