SAM1411 Installation and Use (6806800M91B) 33
One 10/100 BaseT out-of-band interface is accessible via RJ45 connector at the face plate
marked with "ETH". Link and activity status LEDs are integrated into the connector.
Two 10/100 BaseT interfaces are connected to the backplane connector at the pins Eth1-Hub
Tx/Rx and Eth2-Hub Tx/Rx.
These interfaces are compliant with the PICMG 3.0 R3.0 specification (AdvancedTCA) for the
base interface. These ports connect to the base interface of up to two AdvancedTCA switch
boards in the hub slots of an AdvancedTCA shelf.
2.2.2 Redundancy Interfaces
The SAM1411 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 R3.0 (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
2.2.3 Block Transfer Interface
The payload CPU is connected to the ShMC via a parallel interface with interrupt support called
block transfer interface, implemented in an FPGA.
The block transfer (BT) interface is compliant with IPMI specification v1.5.
