CHAPTER 7
Maintaining the ERX System
Storing Modules and Components
Caution: Failure to store electronic modules and components correctly may lead to damage of these items.
Retain the packaging in which a module or component was shipped, and use this packaging to store the item. Modules are shipped in antistatic bags and protective packaging. Components, such as transceivers and NVS cards, are shipped in antistatic plastic containers within an antistatic padded box. Follow these guidelines for storing modules and components:
•Store each module in a separate antistatic bag.
•Store components in an antistatic plastic container. Some of these containers can accommodate several components in separate compartments.
•Do not store multiple modules or components in an antistatic bag or container where they can touch other items.
•(Optional) Store the item in its antistatic bag or container within the protective packaging or padded box that the item was shipped in.
Upgrading NVS Cards on SRP Modules
This section describes how to install
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, the system’s NVS card may become corrupted.
1Enter the halt command.
See ERX System Basics Configuration Guide, Chapter 5, Managing Line Modules and SRP Modules for information about the halt command.
