AdvancedTCA Rear Transition Module Zone 3A Specification
The purpose of this document is to define a set of connectors for data and management on the Rear Transition Module (RTM) described in PICMG 3.0 R3.0. The management protocols are those defined in the IRTM specification. The intent is to define a power/system management connector that can be used by other RTM dot specifications that detail other data connector versions such as coax, fiber optic, etc. This document also details power and cooling issues. This document specifies keying options for various signal levels. It also defines management e-keying that are unique to this spec but follow the guidelines in the IRTM specification. Zone 3A indicates that this is the first definition of connectors for Zone 3. The intent is for other implementations in Zone three to use sequential lettering, e.g. Zone 3B, Zone 3C, etc.
