There is a 2 pin jumper on the  Avnet M14A2A Cellular Shield. What is the function of this? Does this let me switch between USB an UART operation? Please explain in detail. Thanks. Bob

The shield 5V input also connects to a 2-pin jumper (JP2) to optionally source power from the shield to the host board (K64F board in this kit). The default is for the jumper to be installed. All the detail is in: http://cloudconnectkits.org/sites/default/files/5175-GettingStartedGuide...
