Note 1: Each of the J7, J12 and J13 headers must be populated with one jumper for the UCS1003-2 Evaluation
Board to be functional.
2: The headers that select the power supply source (J5 and J8) must always have 2 jumpers populated on
them in total. For more information, see
Section 3.1.1 “Power Source” .
