To replace an NVS card in slot 0 or slot 1 of an SRP module:
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.
