Alcatel-Lucent delivers the OS6900-T40D-R as a true enterprise-grade switch, engineered for high-density, high-performance network backbones and data center deployments. This Alcatel-Lucent switch excels in 10GBase-T environments, supporting advanced Layer 3 management and efficient stackable deployment, which makes it ideal for modern enterprise networking scenarios. The OS6900-T40D-R is built around a modular power supply architecture, enabling seamless integration with redundant power options for maximum uptime. It features a robust managed switching platform with 40 native 10GBase-T RJ45 interfaces, substantial 1.28 Tbps switching capacity, and ultra-low latency of just 3.3 microseconds. In dynamic enterprise networking ecosystems across Asia, Europe, Africa, and North America, flexibility and performance are paramount: this platform’s modular power supply delivers not only high availability but also an optimal cost-to-performance ratio, benefiting distributors, systems integrators, and end users alike. The native support for 10GBase-T ensures straightforward compatibility with existing copper cabling, future-proofs critical infrastructure, and caters to high-bandwidth traffic requirements for both aggregation and ToR scenarios. Enterprise networking teams benefit from strong traffic management, advanced authentication including SSH, RADIUS, TACACS+, and comprehensive protocol support such as IPv6, VRRP, and various spanning tree technologies. With flow control, port mirroring, extensive VLAN support, and robust security implementations, it meets the demands of distributed campus environments and high-availability architectures. Supported worldwide, the OS6900-T40D-R stands as a cornerstone in Alcatel-Lucent’s portfolio, meeting strict international standards and delivering reliable, scalable performance for regional and global deployments.
