1. If the terminal hasn’t shown any information after it has powered on, firstly, we should check the following items:
-If the power supply system is well
-If the switch route processing board is well
-If the configuration cable has connected to the console port of the switch and route processing board?
-If the serial port which configuration cable has connected with is correct? (The actual chosen serial port is not corresponding with the terminal.)
-If the parameters of the configuration terminal has configured correctly (parameter requirement: bit rate: 9600, data bit: 8, parity check: none, stop bit:1, traffic control: none, terminal emulation:VT100 ), as the figure 1-1 displayed:
Figure 1-1 configure the parameters of the configuration terminal
-If the configuration cable is normal.
2. If the terminal displays the garbled characters, it’s most probably the parameters of the configuration terminal have errors, please check the corresponding parameters.
