Compatible Chassis:
- Huawei NetEngine NE40E‑X3 / X3A
- Huawei NetEngine NE40E‑X8 / X8A
- Huawei NetEngine NE40E‑X16 / X16A
- Compatibility Verification: The CR5DL4XEBG7L is specifically designed for Huawei NetEngine 40E series routers. Always verify compatibility with your specific chassis model and software release (V800R008C10 or later) before purchasing .
- WAN Mode Restriction: 10G interfaces 0 to 3 support both LAN and WAN modes. However, interfaces in WAN mode can only function as master interfaces . Also note that 10GE WAN interfaces do not support 1588v2 time synchronisation .
- 1588v2 Support: Huawei documentation lists the CR5DL4XEBG7L as one of the subcards involved in 1588v2 time synchronisation limitations . If deploying PTP/1588v2, please verify specific feature support and restrictions in the applicable configuration guide.
- Hot‑Swap Operation: The board supports hot‑swapping, allowing replacement without chassis power‑down .
- Product Lifecycle: The CR5DL4XEBG7L is an active product within Huawei‘s NetEngine portfolio, supporting current carrier and enterprise network deployments.
- Installation: Professional installation by qualified personnel is recommended to ensure compliance with safety and performance requirements.
