Troubleshooting
This chapter covers potential problems and possible remedies. After each problem description, 
some instructions are provided to help you to diagnose and to solve the problem.
8.1  Problems Starting Up the G-570S
8.2  Problems with the Password
Table 28   Troubleshooting the Start-Up of Your G-570S
PROBLEM
CORRECTIVE ACTION
None of the LEDs 
turn on when I 
plug in the power 
adaptor.
Make sure you are using the supplied power adaptor and that it is plugged in to an 
appropriate power source. Check that the power source is turned on. 
If the problem persists, you may have a hardware problem. In this case, you should 
contact your local vendor.
The G-570S 
reboots 
automatically 
sometimes.
The supplied power to the G-570S is too low. Check that the G-570S is receiving 
enough power.
Make sure the power source is working properly.
Table 29   Troubleshooting the Password
PROBLEM
CORRECTIVE ACTION
I cannot access the 
G-570S.
The Password field is case-sensitive. Make sure that you enter the correct 
password using the proper casing.
Use the RESET button on the rear panel of the G-570S to restore the factory 
default configuration file (hold this button in for about 10 seconds or release the 
button when the PWR LED starts blinking). This will restore all of the factory 
defaults including the password.
