Huawei CR5DMPUX8670 Main Processing Unit
The Huawei CR5DMPUX8670 is a Main Processing Unit (MPU) designed for the Huawei NetEngine 40E-X16A universal service router. As the system's primary control board, it manages the control and management planes, handling routing protocol processing, device management, system monitoring, and clock synchronization for large-scale backbone and metro networks.
The CR5DMPUX8670 works in 1+1 hot backup configuration with a second MPU (typically the CR5DMPUX8673) to provide carrier-grade redundancy. It is designed for the NE40E-X16A chassis, which supports up to 16 line processing units (LPUs), 2 MPUs, and 4 switch fabric units (SFUs) with 3+1 redundancy.
| Feature | Description |
|---|---|
| System Control & Routing | Manages routing protocols including IPv4/IPv6, MPLS, VPN, QoS, and SRv6; handles large-scale routing tables for IP backbone and metro networks |
| 1+1 Redundancy | Supports active/standby MPU configuration with millisecond-level switchover; the OFL button only works on the slave MPU |
| Hot‑Swappable | Supports board replacement without system power‑down. Before removal, press and hold the OFL button for approximately 6 seconds until the OFL indicator turns on |
| System Monitoring | Provides status via RUN (green, 0.5 Hz blink = normal) and ALM (red, steady on = alarm) indicators |

-
Compatibility Verification: This board is specifically designed for the Huawei NetEngine 40E-X16A chassis. Verify compatibility with your specific chassis model and software release (V800R009C10 or later) before purchasing.
-
Redundancy: It is highly recommended to use two MPUs (CR5DMPUX8670 and CR5DMPUX8673) in 1+1 active/standby mode for carrier‑grade reliability.
-
Hot‑Swap Procedure: Before removing a board, press and hold the OFL button for approximately 6 seconds until the OFL indicator turns on. This button only works on the slave MPU.
-
System Capacity: The NE40E-X16A with this MPU delivers 12.58 Tbps non‑blocking switching capacity with 3+1 redundant SFUs.
