This chapter shows an overview of the LEDs and connections on the router.

Structure and connections

Interface(s) number	Description	Note
2	WAN/LAN interfaces: four GE electrical interfaces (GE8 to GE11)	Used as LAN GE interfaces Connector type RJ-45
3	Console interface	Connector type RJ-45
4	RESET button	This button is used to reset the router. To reset and restore the FACTORY settings of the router, hold down the button for at least 30 seconds. To reset the router, hold down the button for less than 5 seconds. Resetting the router will interrupt services. Exercise caution when deciding to press this button.
5	LAN interfaces: eight GE combo interfaces (GE0 to GE7)	Used as LAN interfaces Connector type LC/PC or RJ-45 (combo port) A GE combo interface consists of an optical Ethernet interface and an electrical Ethernet interface on the panel. The two interfaces have only one internal forwarding interface. When either of the Ethernet interfaces is working, the other interface is shut down. GE optical modules (SFP) can be inserted into the eight optical interfaces.
6	WAN/LAN interfaces: ten 10GE optical interfaces (10GE0 to 10GE9)	Connector type LC/PC 10G or GE optical modules (SFP+ or SFP) can be inserted into these ten optical interfaces. Interfaces 8 and 9 cannot be used as LAN Interfaces! Interface 8 is reserved for ABR or Mobile Backup. Interface 9 is used as WAN-Uplink. Interfaces 4 and 5 can be used as link aggregation ports (LAG). Interfaces 6 and 7 are reserved to be used for the sync link in case of EC-XL with sync link.
7	Management interface	Connector type RJ-45 This interface must be used for the Zero Touch Provisioning (ZTP) process during the installation.
8	USB interface 3.0 (not in use)

Description of the LEDs

Number	Indicator	Color	Description
1	PWR	Green (normal state)	Steady on: The router is powered by the built-in power module normally.
		off	The router is not powered on.
	SYS	Green (normal state)	Slow blinking: The system is running properly. Fast blinking: The system is being powered on or restarting.
		red	Steady on: A fault that affects services has occurred and cannot be rectified automatically. The fault needs to be rectified manually.
		--	Off: The system software is not running or is resetting.
	HA (only for EC-XL)	Green (normal state)	Steady on: The device functions as the master device in dual-system hot backup scenario. Blinking: The device functions as the slave device in dual-system hot backup.The device functions as the slave device in dual-system hot backup scenario
		red	Steady on: The device is faulty in dual system hot backup scenario.
		off	The active/standby function is disabled.
	CRTL	Green	Steady on: The SDWAN Controller has managed the router.
		off	The SDWAN Controller does not manage the router.
2	GE electrical interface indicators (GE0 to GE11)	green	Steady on: Data is being transmitted or received on the corresponding GE electrical interface. Blinking: Data is being transmitted or received on the corresponding GE electrical interface.
		off	No link is established on the corresponding GE electrical interface.
3	GE optical interface indicators (GE0 to GE7)	green	Steady on: Data is being transmitted or received on the corresponding GE optical interface Off: No link is established on the corresponding GE optical interface.
		yellow	Blinking: Data is being transmitted or received on the corresponding GE optical interface. Off: No data is being transmitted or received on the corresponding GE optical interface.
4	10GE optical interface indicators (10GE0 to 10GE9)	Green	Steady on: A link has been established on the corresponding 10GE interface. Off: No link is established on the corresponding 10GE optical interface.
		yellow	Blinking: Data is being transmitted or received on the corresponding 10GE electrical interface. Off: No data is being transmitted or received on the corresponding GE optical interface.
5	Management interface indicator	green	Steady on: A link has been established on the corresponding interface. Blinking: Data is being transmitted or received on the corresponding interface.
		--	No link is established on the corresponding interface.
