MA5608T power board

Hello, friend!

PMU indicator on the MPWD board,

Blinking red: The board is being started.

Steady red: A major alarm is generated.

Blinking orange: A common alarm, including a high temperature alarm, is generated.

The operating temperature of the device ranges from –40°C to +65°C.

To improve product reliability, the equipment room should be equipped with a dedicated precision air conditioner to control the temperature and humidity in the following ranges:

Air conditioner control temperature: 15°C to 30°C

The possible causes are as follows:

1. Bit errors occur on the MPWD board.

2. The hardware of the MPWD board is faulty.

3. The hardware is faulty because the ambient temperature is too high.

Contact Huawei technical support or device provider for after-sales maintenance.

Thanks!
