Upgrading NVS Cards on SRP Modules

This section describes how to install higher-capacity NVS cards on SRP modules. The procedure you use depends on the number of SRP modules in the system. A new NVS card will contain the software release you ordered.

Note: The new NVS card must contain the same software release that you are running on the system.

Upgrading a System That Contains One SRP Module

If the system contains only one SRP module, you must power down the system before you upgrade the NVS card. To upgrade the NVS card on a system that contains one SRP module:

Caution: If you do not use the halt command before removing or powering down an SRP module, the system’s NVS card may become corrupted.

1Enter the halt command.

See E-Series System Basics Configuration Guide, Chapter 5, Managing Line Modules and SRP Modules for information about the halt command.

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. This action helps to protect the module from damage by electrostatic discharge.

2Connect the antistatic wrist strap to the ESD grounding jack on the E-series router.

3Power down the system.

4Remove the SRP module.

5Replace the NVS card on the SRP module (see Replacing an NVS Card, later in this chapter).

6Power up the system (see Chapter 7, Powering Up E-Series Routers).
