0305306 Huawei CX600 Series Router Control Module

The Huawei 0305306 is a CX61SRU40A4 System Resource Unit (SRU) designed for deployment in Huawei CX600 series metro services routers. This control and switching board provides the central processing capabilities for the chassis, handling route computation, system management, and forwarding plane coordination.

The CX61SRU40A4 is intended for use in carrier-grade metro Ethernet and IP/MPLS network deployments. It serves as the main processing unit within CX600 platforms, enabling service providers to deliver converged business services including VPN, multicast, and quality-assured transport across metropolitan area networks.

The CX600 series and associated SRU modules represent an established generation of Huawei routing platforms. While these units may be considered legacy in some network environments, they remain operational in many deployed carrier and enterprise networks requiring ongoing support or expansion.
