Huawei SmartAX MA5621 products are the industry's first Multi-Dwelling Unit (MDU) devices designed for power grids,which supports natural heat dissipation and provides 2*GE/2*GPON uplink ports and 4*GE/FE+4*RS232 user ports. The products are mainly used for remote collection and transmission of power system information, such as remote automatic controlling, monitoring,and meter reading. In addition, the products can meet requirements for video monitoring, wireless coverage, and community bandwidth construction.MA5621 series products can be installed in various scenarios, such as on the desk, in the corridor, or outdoors. They feature strong environmental adaptation, easy installation, and convenient maintenance.

Application Scenarios
The MA5621 is used for remote collection and transmission of power system information. In the up-stream direction, an MA5621 is connected to two Optical Line Terminals (OLTs) through two Passive Optical Network (PON) ports for network protection. In the down-stream direction, it is connected to the Remote Terminal Unit (RTU), Feeder Terminal Unit (FTU), and Transformer Terminal Unit (TTU) through the FE and serial ports.The MA5621A is used for the centralized collection of power system electrical meter data. In the upstream direction, the MA5621Ais connected to the OLT through the PON port, while in the downstream direction, it is connected to the concentrator or intelligent electrical meter through the FE or RS485 serial port.
Highlights
•Comprehensive PON protection: The MA5621 series products support both type B and type D protection. An MA5621 is connected to two OLTs through two PON ports, forming a hand-in-hand network against multi-point failures.
• Support for the working temperature ranging from -40°C to 85°C, meeting extreme weather conditions.
•Auto-adaptive 9-60 V direct current (DC) input and 90-290 V alternating current (AC) input, facilitating installation.
• Support for 6 kV surge protection capability, applying to thundery and rainy areas.
• Sealed casting aluminum shell and natural heat dissipation (water- proof, dust-proof, and corrosion-proof).
• Efficient operation, administration, and maintenance (OAM): The MA5621 series products support one-stop deployment, plugand-play, automatic configuration delivery without on-site commissioning, remote monitoring, and remote maintenance.
• Auto-adaptive GE/FE electrical ports and configurable RS232 serial ports, reducing the number of maintenance times.
