The Motorola MXP chassis is fully supported by OpenIPMI, it handles AMC redundancy properly and has (just about) every sensor and control device available. Thanks to Motorola for all their help getting this working. The MXP cards from Motorola have a standard protocol for controlling things not standardized by IPMI, like the blue light on the card, back end power, and on-card reset. For non-MXP cards, the standard CPCI board select and PCI Reset signals are available. All current MXP boards from Motorola, and any future boards, should be automatically supported by OpenIPMI. Extensive documentation is available in the OpenIPMI manual about what sensors and controls are available on the MXP chassis. See the section labelled "Motorola MXP".
