maximum power consumption for the HSMC connector.
Note that the +12V DC power rail goes through a jumper (See
). The function of the
jumper is to avoid cases when users no longer use the 12V power, and the power goes directly to
HSMC daughter boards and thus leads to burning the FPGA I/Os.
This jumper can be found bottom-right corner near the HSMC connector. The factory default setting
is "OFF", meaning the 12V power won't be available to the daughter boards. When users need to
connect the daughter boards, they need to switch the jumper to "ON" position. Please see
