PICMG 2.11 defines the electrical and mechanical interfaces, and minimum
requirements for modular CompactPCI pluggable power supplies and related
CompactPCI platforms based on the CompactPCI core specification PICMG 2.0
R2.1. Although the CompactPCI core specification PICMG 2.0 R2.1 defines an
optional pluggable power supply connector interface; this interface is inadequate to
support many higher power applications. This specification, PICMG 2.1, provides a
defined interface to support higher power supply output current levels and 6U form
factor power supplies, as well as providing some additional functionality to support
Hot Swap applications, and a growth path for high availability systems.
