ATCA Backplane

R1.0, October 2018
3.2.1 Intelligent Platform Management Interface
The Shelf uses an Intelligent Platform Management Bus (IPMB) for
management communications among all ATCA Boards and the Shelf
Managers. The reliability of the IPMB is improved by the addition of a second
IPMB, with the two IPMBs referenced as IPMB-A and IPMB-B.
IPMB-A and IPMB-B are routed to the ATCA slots in a bused configuration.
