SAM1411 Installation and Use (6806800M91B) 44
On board voltages are 12 VDC, 3.3 VDC, 2.5 VDC, 1.0 VDC, and 1.8 VDC:
 12 VDC voltage is generated by the PEMs from the -48 VDC AdvancedTCA power by a
DC/DC converter with galvanic isolation suitable for TNV-2 circuits.
 3.3 V, 2.5 V, 1.0V, and 1.8 V voltages are derived from the 12 V input power.
The board provides two independent power inputs according to the AdvancedTCA
specification. Each input has to be equipped with an additional fuse of max 90 A located either
in the shelf where the board is installed or in the power entry module (PEM).
4.3.3 Rotary Switch Settings
The two rotary switches on the SAM1411 are used to set the SGA. The first byte of the shelf
address of the shelf FRU information is automatically set to the SGA value.
