8.2.2 Redundancy Interfaces
The SAM1410 uses a private, redundant, high-speed, full duplex serial connection for
heartbeating and data replication between the two shelf manager boards.
The redundancy interface is routed to the backplane via differential line LVDS transceivers. The
physical interface of both channels are compliant with the PICMG 3.0 R1.0 (AdvancedTCA)
specification for the update interface.
Each of the serial inputs of the redundancy interface triggers an interrupt to the PowerQUICC
when the other shelf manager board:
 initiates a break-in condition on the serial line
 experiences a power failure
 goes in the reset state
 is extracted
8.2.3 Block Transfer Interface
The payload CPU is connected to the ShMC via a parallel interface with interrupt support called
block transfer interface, implemented in a FPGA.
The block transfer (BT) interface is compliant with IPMI specification v1.5.
8.2.4 Console Interface
The SAM1410 provides one EIA-232 serial interface to the backplane, which is routed to the
Alarm Display Panel (ADP) in the AXP1410 shelf. This can be used for configuration and
diagnostic purposes. This interface is the console port for U-Boot and OS access.
The default baud rate is 9600, 8, N, 1. Pin assignments for this connector are:
