VITA 46.11 chassis manager

According to the SOSA Technical Standard the System Manager Module is responsible to implement functions in order to manage the overall SOSA sensor system. These functions include discovering, configuring, controlling, monitoring and logging health, handling faults, testing, diagnosing and security management. By implementing these functions, the System Manager takes care of the SOSA sensor, so it can fulfill its mission. This is not only expected when the system is operating (in-band), but also when the system is offline or working incorrectly (out-of-band).

The physical implementation or hardware element that allows the system manager to meet all these requirements is the chassis manager according to VITA 46.11. The chassis manager communicates with all components in the chassis and with higher-level entities in the operating environment. It collects information about the operating state, the temperature and the type, number and condition of the installed cards.

Diagnosing and debugging possibilities are enabled via a lower level hardware management interface according to VITA 46.11 even when the system is starting, shutting down, being in an undesired state or when the main power supply is not available.
