Appendix 1 FAQ 

1.  I cannot log in to the webpage of the switch.

  Check whether the switch is powered on properly. 

  Check whether the computer is connected to the switch properly. 

  Check whether the IP address of the computer is set to 192.168.1.

X

 (

and is not be occupied). 

  Clear the cache of the web browser or try another web browser. 

  Disable the firewall of the computer, or try another computer. 

  Check whether only one device with the IP address 192.168.1.110 exists in the local network.

Indicator is solid on and the SYS Indicator is flashing, press and hold the LED Mode button for 
about10 seconds, and release it when all Indicators light up. The switch is restored to factory 
settings when the SYS Indicator flashes again.

switch, and then use the default username and password to log in.
