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
To resolve the issue:
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.

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.
23
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.
