Chapter 3 Important: System Memory Electrostatic discharge (ESD) can damage your board, processor, disk drives, add-in DDR3L boards, and other components. Perform installation procedures at an ESD workstation only. If such a station is not available, you can provide some ESD protection by wear- ing an antistatic wrist strap and attaching it to a metal part of the system chassis.
Connectors COM Express Connector The COM Express connector is used to interface the AL9A3 COM Express board to a carrier board. Connect the COM Express connector (located on the solder side of the board) to the COM Express connector on the carrier board.
