Configuration terminal problems
If the configuration environment setup is correct, the configuration terminal displays booting information when the device is powered on. If the setup is incorrect, the configuration terminal either displays nothing or displays garbled text.
No terminal display
If the configuration terminal displays nothing when the device is powered on, verify the following items:
· The power supply is supplying power to the device.
· The console cable is correctly connected.
· The terminal settings are correct.
Garbled terminal display
If terminal display is garbled, verify that the following settings are configured for the terminal, for example, HyperTerminal:
· Baud rate—9600
· Data bits—8
· Parity—none
· Stop bits—1
· Flow control—none
· Emulation—VT100
Software loading failure
If software loading fails, the system runs previous software version. To troubleshoot the software loading failure:
· Verify that the physical ports are correctly connected. If the cable of any port is not connected, re-connect the cable to the port, and make sure the physical connection is correct. Load the software again.
· Check for errors in the software loading process displayed on the HyperTerminal. If errors exist, correct them, and load the software again.
For example, the software loading failures might occur in the following situations:
· When you use XMODEM to load software, you select a baud rate other than 9600 bps, but you have not reset the baud rate for the HyperTerminal.
· When you use TFTP to load software, you entered an incorrect IP address, software name, or TFTP serve path.
· When you use FTP to load software, you entered an incorrect IP address, software name, username, or password.
If software loading has failed even if the physical connections are in good condition and the software loading process does not have any input errors, contact H3C Support.
