File Storage

Software load files are delivered as tar files, and the".tar" extension must be retained.
Note:
1.7.3 File Storage
Load files can be stored in numerous locations. For example, loads will be stored in FLASH on the control mod-
ule, service module, and could be stored in the users network on a TFTP server, ZMODEM, FTP server, or SD
card.
FLASH memory is a nonvolatile, reusable memory device that allows storage of large volumes of data. RAM is
volatile, dynamic memory that contains the executable software. Software loads are stored in FLASH and RAM
memory on the control module and service module. The primary function of FLASH memory on the system is
to store software releases, simplifying the servicing and maintenance requirements of the system and reducing
recovery time during system restorations. Control modules and service modules are shipped with release files
already present in FLASH memory.
The files on these control and service modules may or may not have the latest release.
Note:
For a duplex system, both control modules have the same files on their respective FLASH file systems. When
both control modules are UP and are in sync, all file operations are automatically applied to both the active and
inactive control module. If the inactive control module is DOWN, it is out-of-sync and file operations are not
performed on it. When the inactive control module is enabled, it performs a bulk sync, and once complete, the
two control modules have file operations applied to both.
Control modules have enough FLASH memory to store two release files for each card type, allowing older and
new releases to coexist in FLASH memory during upgrade procedures. The configuration database is also
stored in FLASH on the control modules. Service modules have enough memory to store a single copy of its
software release file.
When performing an upgrade, management commands retrieve the new release files from a network host and
load them into FLASH memory on the control module and service module.
