Publication No. SBC329-HRM/1
Functional Description 69
5.18 Baseboard Management Microcontroller
The SBC329 uses a microcontroller embedded in the Smart Fusion FPGA to function
as a BMM for implementation of the VPX System Management function in
accordance with VITA 46.11.
The BMM is connected to the following interfaces:
RS232 interface (connected to COM3)
Backplane System Management bus (on the
) via isolation buffers
On-board I
2
C bus (for access to sensor devices)
XMC System Management bus
VPX geographic address
Internal FRU (Field Replaceable Unit) ROM containing the board part number
and serial number
The BMM can reset or power off the SBC329 in response to a System Management
request.
The BMM can control the state of the
