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 normally the console of the Payload Processor, but under
software control, can provide access to the ShMC console instead.
