Applicable EVM Revisions: E2, A
Issue Description: Many cost-saving plug designs do not guarantee a secure, ground-first connection when attempting to hot-plug the J6 DC Barrel Jack connector. This could lead to intermittent brown-out type conditions that may result in damage to the board.
Solution: Hot plugging the power supply is never recommended at the connector end. The “Power On/Off Procedures” outlined in the “Getting Started” section of the document should be followed when applying or removing power from the board. Furthermore, ensure you are using the recommended part number for your EVM Revision as outlined in the Power Supply section of Section 3.1
