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 files to improve download efficiency and security. The download to the SmartNode is handled in
sequence using a download batchfile. Refer to chapter 6,
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 starts the SmartWare applica-
tion. 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 requires no upgrading.
• 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.
• PMC driver software performs the runtime tasks on PMC interface cards mounted in SmartNode 2000
series devices. The PMC drivers are interface card specific and also have build numbers. Refer to the Smart-
