This jack provides maximum of 100W power (for HU171)/ 120W power (for HU173) and is
considered a low power solution. Connect a DC power cord to this jack. We only provide 12V
DC output (for HU171)/ 19V DC output (for HU173) in the package contents. Using a voltage
more than the recommended range may fail to boot the system or cause damage to the sys-
tem board.
