Fault Description

The SYS and PWR indicators of an AR router are both off.

Possible Causes

  • The power switch on the router is turned off.

  • The power cable is not securely connected to the router.

  • The power supply unit has failed.
    • If the router uses a pluggable power supply, the pluggable power supply may fail.
    • If the router connects to an external power source, its power adapter may fail.
    • If the router has a built-in power supply, the router itself may be faulty.

Troubleshooting Procedure

  1. Check that the power switch is on.

  2. Check that the power cable is securely connected to the router.

  3. Check whether the power supply is normal.

    • If the router uses a pluggable power supply, replace the pluggable power supply with a normal one. If the router is powered on, the original pluggable power supply is faulty. Contact Huawei technical support or Huawei agent through Hotline&Email and ask them to replace the pluggable power supply.
    • If the router uses a power adapter, replace the power adapter with a normal one. If the router is powered on, the original power adapter is faulty. Contact Huawei technical support or Huawei agent through Hotline&Email and ask them to replace the power adapter.
  4. If the router still cannot be powered on, the router itself is faulty. Contact Huawei technical support or Huawei agent through Hotline&Email and ask them to replace the router
