When you modify the settings for the console port of the router, configure the same settings for the
console terminal.
Troubleshooting the router during the operation
At the CLI, you can use related commands to display the router information and locate the failures.
For more information about how to display the router information, see device management in
H3C
SR8800-F Routers Fundamentals Command Reference
.
If you detect any configuration error, re-configure the router or restore the factory defaults for the
router.
Troubleshooting the power supply system
If the router operates correctly, the status of the LEDs related to the power supply system is as
follows:
•
The LED on the power supply is green. On a power supply with multiple LEDs, each LED
indicates the status of a function. For more information, see "Power supply LEDs."
•
For the PWR LEDs on the MPU:
If the MPU has only one PWR LED, the LED is green.
If the MPU has two PWR LEDs, the OK LED is on, and the FAIL LED is off.
For more information about the PWR LEDs on an MPU and the LEDs on a power supply, see
"Appendix C LEDs."
NOTE:
After the power source is disconnected from the power supply, it is correct that the LEDs stay on for
a period of time.
If the LEDs do not conform to the status mentioned above, the power supply is operating incorrectly.
To troubleshoot the power supply system:
1.
Verify that the power supply is switched on.
2.
Examine whether the power supply is over-temperature. When a power supply is
over-temperature, it enters the self protection state. Make sure the router is correctly ventilated.
3.
Verify the power cord connections. If a power cord is loose, connect the power cord again. If a
power cord is broken, replace it.
4.
Verify the power supply installation. If the power supply is not fully seated, re-install the power
supply to make sure it has a close contact with the backplane of the router.
5.
Verify the power supply system. Make sure the power supply system is operating correctly and
provides a normal voltage.
6.
If the router has empty power supply slots, install the power supply in an empty power supply
slot, and verify that the power supply can operate correctly.
7.
Install a new power supply of the same model in the same slot, and connect it to the same
power supply. If the new power supply can operate correctly, the old power supply is faulty.
Contact the local agents for replacing the old power supply.
