Checking after power-on After powering on the router, verify the following items:

• The LEDs on the front panel are normal, as described in "LED description."

• The console terminal displays information correctly. You can see the startup window on the local console terminal. For more information, see "Displaying boot information."

• After completing the POST, the system prompts you to press Enter. When the command line prompt appears, the router is ready to configure.

Configuring basic settings for the router After the router is powered on for the first time, configure basic settings for the router. For more information, see H3C MSR Series Routers Configuration Guides and H3C MSR Series Routers Command References.

Troubleshooting

IMPORTANT:

• The barcode on the router chassis contains product information that must be provided to local sales agent before you return a faulty router for service.

• Keep the tamper-proof seal on a mounting screw on the chassis cover intact, and if you want to open the chassis, contact H3C for permission. Otherwise, H3C shall not be liable for any consequence.

Power supply failure Symptom

The router cannot be powered on and LEDs on the front panel are off.

Solution

To resolve the issue:

1. Power off the router.

2. Verify that the router's power cords are connected firmly.

3. Verify that the power source is operating correctly.

4. Determine if the power cord is damaged.

5. If the issue persists, contact H3C Support.

System configuration problems If the configuration environment setup is correct, the console terminal displays boot information when the router is powered on. If the setup is incorrect, the console terminal displays nothing or garbled text.

No terminal display Symptom

The console terminal displays nothing when the router is powered on.

Solution


1. Verify that the power supply system is operating correctly.

2. Verify that the console cable is connected correctly.

3. Verify that the console cable is connected to the serial port of the console terminal.

4. Verify that the following terminal settings are correct:

Bits per second—9600.

Data bits—8.

23

Parity—None.

Stop bits—1.

Flow control—None.

Terminal Emulation—VT100.

5. Verify that the console cable is operating correctly.


Garbled terminal display Symptom

Terminal display is garbled.

Solution


1. Make sure the Data bits field for the console terminal is set to 8. If the Data bits field is set to 5 or 6, the console terminal will display garbled characters.


No response from the serial port Symptom

The serial port gives no response.

Solution


1. Verify that the serial cable is in good condition and the serial port settings are correct.


Restoring the factory settings

Scenario 1 Symptom

When you replace the router, the router password is lost. As a result, you cannot log in to the router and do not know the router configuration.

Solution

Because the router is replaced, you do not need to save the configuration of the router. In this case, you can press the Reset button for more than 4 seconds to reboot the router and restore the factory settings. Then, you can use the username and password shipped with the router to log in to the router.

When the router configuration must be saved and you have a console cable, you can log in to the router from the BootWare menu.

24

Scenario 2 Symptom

After the configuration is modified, the network connectivity is lost. When you check the configuration, the configuration is very complicated and it is hard to locate the errors. In this case, you must configure the router again.

Solution

If you have not saved any configuration, you can reboot the router by pressing the Reset button for a short time or power off the router.

If you have saved the configuration, delete the configuration file at the CLI, and press the Reset button to restore the factory settings.

Scenario 3 Symptom

The router crashes.

Solution

Press the Reset button for a short time to reboot the router.

Reset button usage guidelines An MSR900-E router provides the Reset button. You can use the button to reboot the system or restore the factory settings.

• Press the Reset button for a short time to reboot the router.

• Press the Reset button for more than 4 seconds to reboot the router and restore the factory settings.
