installing software, and about NVS cards and SRP modules, see:

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 already contains 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.
CAUTION: If you do not use the halt command before removing or powering down
an SRP module, the system's NVS card can become corrupted.
