When the input/output LEDs are off or the fault LEDs are on, the power supply does not work properly.
To troubleshoot the power supply system:
Examine the power cable connections. If a power cable is loose, plug it in.
1.
Replace the power cable and verify that the LEDs are normal.
2.
Examine the power supply installation. If the power supply is not seated properly, reinstall the
3.
power supply so that it makes close contact with the router.
Examine the power source. Make sure the power source is operating properly and provides a
4.
normal voltage.
Determine whether the power supply has encountered output short circuit, output over-current,
5.
output over-voltage, input under-voltage, or over-temperature problems.
Power off the router, plug the power supply into an empty power supply slot, and verify that the
6.
power supply is operating properly. If the power supply is operating properly, the power
supply slot may have failed. Otherwise, proceed to the next step.
Plug a new power supply of the same model into the same power supply slot and connect it to
7.
the same power source. If the new power supply is operating properly, the old power supply
fails. Contact the agents to replace the old power supply.
