3.3.2 Placing devices in the 40-pin socket

1. Use any of these methods to make sure that power is not applied to the sockets before placing or replacing devices into this socket.
   • Move S1 to the middle position, so that neither the PMBus adaptor nor the J2 connector supplies power
   • Remove the power supply to J2 when S1 is in the right position.
   • Remove the PMBus adaptor connection when S1 is in the left position.
   • Switch S2 to the OFF position when the board operates in Manual mode.
   • Pull the PMBus CNTL pin low when the board operated in Automatic control mode.
2. Properly insert the device to match the Pin 1 marking on the board.
3. Close and latch the socket lid firmly before applying power to the device.
4. Make sure that both VREF_ON LEDs illuminate before you continue NVM programming.
