Power Supply Mode

Possible Cause

PoE power supply

The power sourcing equipment does not
support the PoE function or is faulty.

The power sourcing equipment does not
support the required power supply mode.

The power sourcing equipment does not
provide sufficient power.

The power sourcing equipment is
incorrectly configured (the PoE function
is disabled or the power-off time range is
improperly set).

The line is faulty (the network cable or
distribution frame is damaged).

The device is faulty.

Troubleshooting Procedure

Power Supply Mode

Troubleshooting Procedure

Power supply using a power module

1. Check whether the device is powered

off.

2. Check that the power cable is securely

connected to the device.

3. Check whether the power supply is

normal.
Replace the power adapter with a normal
one. If the device is powered on, the
original power adapter is faulty. Contact
technical support personnel or Huawei
agent and ask them to replace the power
adapter.

4. If the device still cannot be powered on,

the device itself is faulty. Contact
technical support personnel or Huawei
agent and ask them to replace the device.
