Appendix A Troubleshooting

Q1. What could I do if I forgot the username and password of the switch?
1. Connect the console port of the PC to the console port of the switch and open a terminal
emulation program.
2. Power off and restart the switch. When you are prompted that "Hit any key to stop
autoboot" in the terminal emulation program, please press any key to enter into bootUtil
menu shown as the following fi gure.
3. Enter the number 6 to select the "Password recovery" option and enter Y to delete all
the users and passwords. The default login username and password are both admin. The
other confi gurations in the switch will not be changed.
Q2. Why does the PWR LED work abnormally?
The PWR LED should be lit up when the power system works normally. If the PWR 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.
Q3. What could I do if I could not access the web-based confi guration page?
You are recommended to check the following items:
1. Check every port LED on the switch and make sure the cable is installed 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 confi guration page, please restore the switch to its factory
defaults. Then the IP address should be set as 192.168.0.x ("x" is any number from 2 to
254) and Subnet Mask as 255.255.255.0.
