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.
5.1.1
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
4.1.2 Set PC HyperTerminal Parameters
.
3. There is something wrong with the configuration cable and you can try to change the
configuration cable.
5.1.2
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
4.1.2 Set
