WHITE PAPER: Critical Aspects of Chassis Management

While sometimes thought of as mundane, SOSA management and support modules play critical roles in maintaining reliable operation of complex sensor systems. This paper examines how the chassis manager provides the out-of-band interface to Plug-In Cards (PICs) as well as the needed in-band system management interactions of MOSA systems aligned to the SOSA Technical Standard.
