The 

24+2G 

Switch has a universal power supply and you can power up the Switch with 90 

~ 260V AC, 50 ~ 60Hz power source. The AC power cord connector is located at the rear 

of the unit and the On/Off switch is next to the connector. Connect the power cord from 

the power outlet to the Switch and push the On/Off Switch to “ON” position to power on 

the Switch. After the Switch is powered on, it will perform “self-diagnostic” (POSD). This 

process takes about 100 seconds to complete, during this process, the “DIAG” LED will 

blink green and the Switch will not response to any configuration program and all the 

connections to the Switch will not be available. When the processed is completed, the 

“DIAG” LED will stay solid green. 

Below is a table that describes the meaning of each LED indicator.
