ATCA Backplane 6 R1.2, March 2018
3 ATCA Backplane
The 2-slot ATCA monolithic Backplane is completely passive and is not A Field Replaceable
Unifield replaceable. The backplane provides 40Gb/s connectivity (4 lanes with 10Gb/s) and
2 ATCA slots in a:
•Hub/Hub configuration (Backplane 90183-490) or
•Node/Node configuration (Backplane 90183-491)
3.1 Logical to Physical Slot Mapping
The physical and logical slots are sequentially numbered from the lower to the upper slot.
Table 2: 2-Slot ATCA Backplane physical to logical slot mapping
3.2 Interfaces
3.2.1 Fabric Interface
All 15 Fabric Channels of slot 1 are routed to the respective Fabric Channels of slot 2.
3.2.2 Synchronization Clock Interface
6 pairs of synchronization clocks are bused between both ATCA slots and terminated at both
ends.
3.2.3 Update Channel Interface
The Update Channels are wired between both ATCA slots. The Update Channel can be used
to pass data or routing information between two redundant ATCA Boards.
3.2.4 Intelligent Platform Management Interface
The Shelf uses an Intelligent Platform Management Bus (IPMB) for management
communications among all ATCA Boards. 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.
The IPMB-A and IPMB-B are routed between the ATCA slots.
