	74	+1). When the gateway is connected to the power supply, power will light up first, then the earth light and eth will flash together once

	84	+1.) When you plug in the power supply the LED of the power/global/LAN will blink once, and then the power led will light on.
	85	+
	86	+If you can get this process where it says your gateway's hardware is not defective.
