|---|---|---|---|
| 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 | Connected to the console for onsite system configuration. The default baud rate is 9600 Baud, and the baud rate is configurable. | 8-core shielded cable |
| AUX | RJ45 | Used to redirect traffic to a serial port of the peer device. The default baud rate is 9600 Baud. | 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 | 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 |
Hot swapping is supported. The 1:1 backup mode is adopted. |
| Restrictions and remarks | In V800R025C00SPC500 and later versions, this main control board can be used with the ME0DMPUX867A/ME0DMPUX8676. Different types of boards have different maximum power consumptions. After an original main control board is replaced with another type of main control board, ensure that an additional power margin of at least 20 W is available compared to the original configuration. Otherwise, a power insufficiency alarm may be generated. Other scenarios do not support mixed use of different types of main control boards. |
| Breakout supported | No |
| Interface rate auto-sensing supported | No |
| Link protocol | - |
