| Part Number | 03050DEW-001 |
| Model | ME0DMPUX8672 |
| Card type | MPU |
| Silkscreen | MPUB11 |
| Port | Connector Type | Description | Available Components |
|---|---|---|---|
| FSP0, FSP1 | RJ45 | Reserved. It functions as an interface for fast chassis switchovers. | 8-core shielded cable |
| GE/10GE | SFP/SFP+ | Reserved cascading interface. | Optical fiber |
| HP-GE0, HP-GE1 | SFP | High-precision clock interface. | Optical module (34060286/S4016067/34060484) and Atom GPS timing SFP module (03034CGQ) |
| MGMT-ETH | RJ45 | It connects to an NMS and can work in half-duplex or full-duplex mode. | Super category 5 shielded twisted pair |
| CON | RJ45 | It connects to the console for on-site system configuration. Baud rate: 9600 bit/s (default value), which is configurable. | 8-core shielded cable |
| AUX | RJ45 | Used to redirect to the serial port of the peer device. The default baud rate is 9600 bit/s. | 8-core shielded cable |
| CLK | RJ45 | Used to input or output 2 Mbit/s clock signals, 2 MHz clock signals. | 120-ohm clock cable. If the peer end is an SMB interface, a 120 ohm-75 ohm converter box is required. |
| TOD | RJ45 | Used to input or output 1pps+ASCII time signals, or two channels of DCLS time signals. | 120-ohm clock cable. If the peer end is an SMB interface, a 120 ohm-75 ohm converter box is required. |
| CLK-INT | RJ45 | Inputs or outputs 2 Mbit/s clock signals, 2 MHz clock signals, 1pps+ASCII time signals, or two channels of DCLS time signals. It is reserved. | 120-ohm clock cable |
| CLK/TEST | SMA | Used for clock tests. | 50-ohm clock cable |
| USB | USB Type A | USB interface, reserved for future use. | - |
| Functions and Features | Description |
|---|---|
| Basic function | It is responsible for system control and management, including route calculation, device management and maintenance, and device monitoring. In addition, it functions as the system synchronization unit to provide high-precision and high-reliability synchronization clock and time signals. |
| Reliability and availability | 1:1 backup mode. |
| Restrictions and remarks | Cannot be installed in the same chassis with main control boards of other models. In V800R021C10SPC500 and later versions, this main control board can be installed in the same chassis with that of the same model (part number: 03050DEW). |
| Breakout supported | No |
| Interface rate auto-sensing supported | No |
