Equipped with dip switch function
(Three digit dialing code)
Eight built-in working modes that can be selected online for gigabit switches:
	① Standard mode, 
	② Cross device QinQ isolation mode, 
	③ Uplink port link aggregation mode
	④ Based on downstream port VLAN isolation mode, 
	⑤ forced 10M mode for electrical ports, 
	⑥ cross device QinQ
	Isolation+forced 10M mode for electrical ports, 
	⑦ VLAN isolation based on downstream ports+forced 10M mode for electrical ports Mode:
	 ⑧ The optical port is in high priority mode and the electrical port is in low priority mode.
	Note: Customers can also customize other working modes of the switch according to their actual needs.

LED indicator light
Power indicator light: PWR (green light), interface indicator lights are as follows:
① The gigabit optical port has a green light indicating 1000M. (Above the power light)
② For the gigabit electrical port, when the yellow light is on, it indicates Link/ACT, and when the yellow light is off, it indicates link down status;
The yellow light is on and flashing, indicating that the port is in link up status and sending and receiving data;
③ POE port section (ports 1-8), green light indicates normal power supply connection;
	Green light off indicates abnormal POE power supply;
