3.3 SmartWare Embedded Software
SmartWare is the application software that runs on the SmartNode hardware platforms. SmartWare
is available in several releases that support all available SmartNode models. Refer to the SmartWare
release notes for detailed information about hardware support.
For each SmartWare release there are platform-specific
build
numbers. There may be more than one
build per release and platform as updates become available. Refer to the SmartWare release notes for
build numbers and build-specific enhancements and limitations.
A SmartWare build is a binary image file. A SmartWare build is usually divided into several
checksum-protected download files to improve download efficiency and security. The download to
the SmartNode is handled in sequence using a download
batchfile
. Refer to Chapter 8, “System Image
Handling”, for details on SmartWare image downloads.
In addition to the actual SmartWare images there are several additional embedded software
components that you will encounter:
•
The
boot loader
is a “mini” application that performs basic system checks and which starts the
SmartWare application. The boot loader also provides minimal network services, allowing
the SmartNode to be accessed and upgraded over the network even if the SmartWare
application should not start. The boot loader is installed in the factory and is never
upgraded.
•
The
PMC loader
initializes PMC interface cards when mounted in SmartNode 2000 series
devices. It checks hardware versions and determines whether compatible PMC drivers are
available. The PMC loader may be upgraded together with a SmartWare release.
