3 Troubleshooting

Power failure

Symptom

The device cannot be powered on. The system status LED (SYS) is off.

Solution

To resolve the issue:

1.        Verify that the power source is as required by the device.

2.        Verify that the power cord is connected securely.

3.        Verify that the power cord is in good condition.

4.        If the issue persists, contact H3C Support.

No display or garbled display on the configuration terminal

Symptom

The configuration terminal does not have display or have a garbled display when the device is powered on.

Solution

To resolve the issue:

1.        Verify that the power system is operation correctly.

2.        Verify that the console cable is connected correctly to the specified serial port on the configuration terminal.

3.        Verify that the following settings are configured for the terminal:

¡  Baud rate—9,600.

¡  Data bits—8.

¡  Parity—none.

¡  Stop bits—1.

¡  Flow control—none.

¡  Emulation—VT100.

4.        Verify that the console cable is in good condition.

5.        If the issue persists, contact H3C Support.

Software loading failure

Symptom

The device fails to load software.

Solution

To resolve the issue:

1.        Verify that the physical ports are connected securely and correctly. If a port is not connected securely, reconnect the port and make sure the connections are correct.

2.        View the software loading process displayed on the HyperTerminal to check for errors. If an error exists, correct the error.

For example, check for the following errors that might occur:

¡  You used XMODEM to load software and set a baud rate other than 9600 bps, but you have not reset the baud rate for the HyperTerminal.

¡  You used TFTP to load software and entered an incorrect IP address, software name, or TFTP serve path.

¡  You used FTP to load software and entered an incorrect IP address, software name, username, or password.

3.        If the issue persists, contact H3C Support.
