TROUBLESHOOTING
5.1.
Troubleshooting of Configuration System
After the router is powered on and if the system is normal, the start information is displayed
on the configuration terminal. If the configuration system fails, there may be no display or
messy code on the configuration terminal.
1.5.1.
Troubleshooting about no Display on Terminal
If there is no display information on the configuration terminal after being powered on, check
according to the following steps:
Step 1:
Check whether the power system of the router works normally
Step 2:
Check whether the indicator on the front panel of the router works normally.
Step 3:
Check whether the configuration cable is connected to Console port on the front
panel of the router.
If no problem is found in the above checks, there may be the following reasons:
1.
The serial port connected to the configuration cable is wrong (the actual selected serial
port is not consistent with the set serial port of the terminal).
2.
The setting of the configuration terminal parameters is wrong (the parameter requirement:
set the baud rate as 9600, data bit as 8, parity check as none, stop bit as 1, traffic control as
none, and select the terminal emulation as VT100). For details, refer to
3.
There is something wrong with the configuration cable and you can try to change the
configuration cable.
2.5.1.
Troubleshooting about Messy Code on Terminal
If messy code is displayed on the configuration terminal, maybe the setting of the
configuration terminal parameters is wrong (set the baud rate as 9600, data bit as 8, parity
check as none, stop bit as 1, traffic control as none, and select the terminal emulation as
VT100), and please check correspondingly. For details, refer to
5.2.
