The AP fails to start

Perform the following operations to handle AP start failure:
1. Observe the status of the AP power indicator or the information output through the serial port to determine whether the AP is not powered on or the AP cannot start after power-on.
- If the AP can be powered on but cannot be logged in, contact Huawei technical support.
- If the AP cannot be powered on, go to step 2.
2. Check the AP's power supply mode.
- If the DC power adapter is used to supply power to the AP, check the source of the power adapter.
- If the power adapter is supplied with the AP, go to step 3.
- If the power adapter is purchased from another vendor, check whether its rated output voltage and current meet the requirements for Huawei AP products. If not, replace the power adapter. It is recommended that you use the power adapter supplied with the AP.
- If PoE is used to supply power to the AP, see "Why Does an AP's PoE Fail to Be Powered On" in Huawei support website.
- For AC power supply, use a multimeter to check whether the cable connection is normal and whether the output voltage of the power supply meets AP requirements. You can also perform a cross test using other AC power supply devices. If the output voltage of the power supply does not meet AP requirements, contact Huawei technical support.
3. Perform a cross test on the AP using the DC power adapter.
- If the AP cannot be powered on, contact Huawei technical support.
- If the DC power adapter is faulty, replace it.
