|5||4||The ORBIT Chassis Manager (CM) is a simple, reliable, platform-independent subsystem for managing and autonomously monitoring the status of each node in the ORBIT network testbed. Currently there are 2 versions of the CM that are being used. The [wiki:Hardware/jCM/bCM1 CM1] is used to control the generation 1 nodes, and the [wiki:Hardware/jCM/dCM3 CM3] is being used to control the newer generation 3 nodes. [wiki:Hardware/jCM/cCM2 CM2] was designed for the generation 2 nodes, which are no longer being used. There are basic [wiki:Hardware/jCM/aRequirements requirements] of all the CMs must preform common through all the revisions, those some of the details change.
