1	USB interface (host)	2	Two 3G antennas
3	Console interface	4	WAN interface: GE electrical interface
5	LAN interfaces: four GE electrical interfaces NOTE: GE0 is a management interface and is used to upgrade the router. V200R007C00 and later versions: all GE LAN interfaces can be configured as WAN interfaces.	6	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.
7	Two SIM card slots NOTE: The mounting holes at two sides of the SIM card slots are used to fix the SIM card cover with screws. The double-card single-standby is supported, and SIM1 is the default master card. If only one SIM card needs to be installed, install it in slot SIM1. When installing a SIM card, ensure that the notch direction of the SIM card is consistent with that of the SIM card slot. The standard SIM card is supported. It is not recommended to use the card cover to prevent poor SIM card contact. Hot-swap SIM card is not supported. After replugging the SIM card, you need to restart the RF module or restart the device.	8	Power jack NOTE: The router uses a 24 W integrated power adapter.
9	Jack for power cable locking strap NOTE: Insert a power cable locking strap in this jack to secure the power cable.	10	3G-U antenna interface
11	Product model silkscreen	12	Ground point NOTE: Reliably ground the router by connecting a ground cable to the ground point to protect the router against lightning and interference.
