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 hyper terminal.   

2. 

Power off and restart the switch. When you are prompted that “Press 
CTRL-B to enter the bootUtil” in the hyper terminal, please press 
CTRL-B key to enter into bootUtil menu shown as the following figure. 

 

 

 

 

 

 

 

 

 

3. 

Enter the reset command to reset the system. The system will be reset 
to the factory default settings, and the default login user name and 
password are both “admin”. 

Q2. Why does the Power LED work abnormally? 

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. 

Q3. What could I do if I could not access the web-based configuration 
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.
