Overview
When managing modules, you need to consider both software and hardware
procedures. For example, before you remove an SRP module, you must enter the
halt command to prevent damage to nonvolatile storage (NVS).
This chapter describes the software issues associated with managing modules. Each
section in the chapter covers a different topic; where appropriate, a section contains
an overview of the topic, configuration tasks, and information about monitoring the
associated settings.
