Shelf Manager Hardware
SAM1411 Installation and Use (6806800M91B) 32
The alignment pin offers a guiderail to the slot and a coding mechanism to ensure the
installation of the board in the matching slot. It also prevents bent pins which may occur during
installation.
The hardware consists of:
 Payload hardware section with
– Ethernet interfaces to the backplane and to the face plate
– Redundant connection between two shelf managers via backplane
– Block transfer interface to the ShMC
 Shelf management controller section with
– IPMB0-A and IPMB0-B interface to the backplane
– Handle switch and status LED interface to the face plate
 Support logic for testing and debugging, as well as local and remote programming of all
programmable devices on the board
 Power supply
2.2 Payload Hardware
The payload hardware on the shelf manager board is always powered when power supply is
present. During power-on, the ShMC keeps the payload in a reset state.
The following interfaces are available:
 Three Ethernet interfaces
 Two redundancy interfaces (serial)
 Block transfer interface
 One diagnostic console interface (serial)
2.2.1 Ethernet Interfaces
The shelf manager board has three Ethernet ports which are available concurrently.
