Troubleshooting the router during the operation

Use
display
for exceptions.
If any configuration error is found, re-configure the router or restore the factory-default settings.

Power supply system failure

If the router is operating correctly, the LEDs on the power supply (AC LED and DC LED) are green.
For more information, see H3C CR16000-F Router Series Hardware Information and Specifications.
After a power supply is disconnected from its power source, it is normal that the power LEDs stay ON
for several seconds.
If the power LEDs are off or not green, examine the power supply for an exception, as follows:
1. If the DC LED is orange, the power supply has transitioned to the over-temperature protection
state. Examine the cooling system for inadequate ventilation, and make sure every empty slot
has been covered by a filler panel.
2. If the DC LED is red, the power supply has transitioned to a self-protection state because of a
power supplying problem. Examine the power supply for output short circuit, output
over-current, output over-voltage, input under-voltage, or remote disconnection.
The DC LED also turns red if the input of the power supply is disconnected while the other
power supply is operating correctly. In this case, connect the input or keep the input
disconnected as needed.
3. Examine the power cord connections. If a power cord is loose, connect the power cord again. If
a power cord is broken, replace it.
4. Examine 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. Examine the power supply system. Make sure the power supply system operates correctly and
provides a normal voltage.
6. If the router has empty power supply slots, remove the power supply, install the power supply in
an empty power supply slot after all LEDs on the power supply are off, 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 input end. If the new power supply can operate correctly, the old power supply has failed.
You must replace the old power supply.

Fan failure

Both the MPU and the fan tray provide the fan tray LEDs, including an OK LED and a FAIL LED.
When the fan tray operates correctly, the OK LED is on, and the FAIL LED is off.
If the OK LED is off or the FAIL LED is on, the fan tray has failed. To troubleshoot the fan tray:
