1	USB interface (host)	2	CON/AUX interface NOTE: The AR201 does not support AUX login.
3	WAN interface: FE electrical interface	4	LAN interfaces: eight FE electrical interfaces NOTE: LAN interface FE0 can be configured as a WAN interface. FE6 is a management interface and is used to upgrade the router. V200R007C00 and later versions: all FE LAN interfaces can be configured as WAN interfaces.
5	RESET button NOTE: This button is used to reset the router. To restore the factory settings, hold down the button for at least 5 seconds. To reset the system, press the button for less than 5 seconds. Resetting the router will interrupt services. Exercise caution when deciding to press this button.	6	Power jack NOTE: The router uses a 4-pin 36 W power adapter.
7	Jack for power cable locking strap NOTE: Insert a power cable locking strap in this jack to secure the power cable.	8	Product model silkscreen
9	Ground point NOTE: Reliably ground the router by connecting a ground cable to the ground point to protect the router against lightning and interference.	-	-
