LOS	See Table 2.
LAN1～LAN4	Always on	The Ethernet connection is in the normal state.
	Blinks	Data is being transmitted on the Ethernet port.
	Off	The Ethernet connection is not set up.

PON and LOS are GPON LEDs. The status of PON and LOS reflects the connection between MA5671& and the optical line terminal (OLT). The following table describes the status of the PON and LOS LEDs.

Table 2. LED status indications 2

No.	LED Status		Description
No.	PON	LOS	Description
1	Off	Off	The ONT is disabled by the OLT.
