With the switch powered on, press the Reset button on the front panel
for five seconds to reset the system to its factory default settings, and the
default login user name and password are both admin.
The Power LED should be lit up when the power system works normally. If
the Power LED worked abnormally, please take the following steps:
1. Make sure that the power cable is connected properly, and the power
contact is normal.
2. Make sure the voltage of the power supply meets the requirement of the
input voltage of the switch.
You are recommended to check the following items:
1. Check every port LED on the switch and make sure the cable is
connected properly.
2. Try another port on the switch and make sure the cable meets the
requirement and works normally.
3. Turn off the power. After a while, turn on the power again.
4. Make sure the IP address of your PC is set within the subnet of the
switch.
5. If you still cannot access the configuration page, please restore the
switch to its factory default. Then the IP address should be set as
192.168.0.x ("x" is any number from 2 to 2541 and Subnet Mask as
255.255.255.0.
