Replacing an NVS Card

To replace an NVS card on an SRP module:
CAUTION: Before you insert or remove an NVS card from a running SRP module,
we strongly recommend that you halt the SRP module or shut down the router.
Failure to do this can result in file corruption in one or both cards. See JUNOSe System
Basics Configuration Guide, Chapter 6, Managing Modules for information about the
halt command.
