LED		Description
Power		On (green) when power is applied to the unit. Off
		when no power is applied to the unit.
CopperLink -		On (green) when the end-to-end CopperLink link
Link		between the units is established. Off when the link
		has not been established or when the link fails
CopperLink -		Flashes yellow at different rates to indicate the
QOL		amount of error correction taking place on data pass-
		ing over the CopperLink link. This is a normal operat-

		LED is solid yellow and the CopperLink Link LED
		is Off, then there is too much noise on the line for an
		active link.
