Huawei DSLAM MA5616 Power Distribution Principle and Working Principles

Power Distribution Principle

Huawei MA5616 can be powered by a DC or AC power source through a DC or AC power board. The power board outputs -48 V DC, +3.3 V DC, and +12 V DC power to the backplane. Then the backplane provides the -48 V DC and +3.3 V DC power for the service board and control board, and provides the +12 V DC power for the fan monitoring board.

Working Principles

Huawei MA5616 supports GPON, 10G GPON or GE upstream CCUE transmission by using its control board and provides broadband and narrowband access services by using different service boards.

Working principles of the MA5616 chassis 

The working principles of Huawei DSLAM MA5616 chassis are as follows:

• The control board transmits services upstream and subtends device through subboards and manages service boards.
• The power board outputs DC power to the backplane and then the backplane transmits the power to the fan tray, service boards, and control board.
• The broadband or narrowband service board is connected to a user-side device by using a subscriber cable, and then the control board puts the user-side device through to the IP network. In this way, broadband or narrowband access service is provisioned to the user-side device.
• The fan monitoring board monitors the fan tray and transmits the monitoring signal to the control board through the backplane.
