Troubleshooting
5.1 Troubleshooting Power Faults
For RSR10-02 and RSR20-04 series, you can determine whether the power system has any
fault by the Status indicator on the front panel. For RSR20-14, RSR20-18 and RSR20-24,
however, you can determine whether the power system has any fault by the POWRE
indicator on the front panel. For the normal status of the indicator, see the description on the
first chapter. If any abnormal situations occur, please make the following checks:
 If the router power switch is in the on position.

If the power supply switch of the router is in the on position.
 If the power cable is connected correctly.
 If the power supply meets the requirements.
Warning
Do not plug/unplug the power cable when energized. If the check shows
everything is normal but the POWER/Status indicator is still off, please
contact the local distributor or technical support team.
5.2 Troubleshooting Configuration
Faults
After the router is powered on, the terminal will show the startup messages described in
Chapter 4 if the system is normal. If the configuration system fails, the terminal may display
no messages or illegible codes.
If the terminal does not display any messages, please make the following checks:
 Whether the power system is normal.
 Whether the Console cable is properly connected.
If the steps above did not solve your problem, it is likely because of wrong configuration
cable or wrong terminal parameter setting. Please check terminal parameters.
If illegible codes occur on the terminal, the possible cause is that terminal parameters
configured do not match. Please check the terminal parameters: baud rate of 9600; 8 data
bits; no parity check; 1 stop bit; no flow control; VT100 for simulation terminal.
