3.1 Separate Power Rail

Users have the option to read and write to registers of each PHY on the EVM without having the EVM connected to the AST2600 EVB. To do this, users must populate the headers circled below and apply 12V across the “12V” and “GND” pins. The 12V connection is the top left pin in J701, while GND pins are any pins on the outer side of the header.
