Cisco 5700 Line Card

The Cisco 5700 Line Card represents a bold leap in high-speed networking for the NCS 5700 family, delivering unprecedented 400GE performance to meet the demands of modern data centers and cloud networks. This next-generation module is engineered to dramatically increase forwarding capacity, supporting dense, scalable deployments that power service providers, hyperscale operators, and large enterprises. With engineering rooted in Cisco’s Global Cloud Index insights, the 5700 line card is designed to accelerate digital transformation, enabling faster traffic movement, smarter routing decisions, and improved overall network efficiency across core, edge, and data center interconnect architectures. By integrating high-speed forwarding with robust reliability and programmability, it helps customers reduce latency, lower total cost of ownership, and future-proof their networks against growing traffic volumes and evolving service requirements.

• 400GE forwarding capability with high-density port support: The 5700 Line Card is purpose-built for dense 400 Gigabit Ethernet deployments, enabling scalable spine-leaf fabrics, enhanced datacenter interconnects, and rapid service provisioning across large-scale networks. Its architecture is optimized to handle diverse traffic types—from bulk data transfers to bursty AI workloads—while preserving line-rate performance.
• Exceptional throughput scaling: up to 153.6 Tbps per system: This model delivers a maximum system-wide forwarding capacity of 153.6 Terabits per second, dramatically expanding the headroom available for ultra-fast traffic paths, large-scale EVPN/VXLAN environments, and other demanding use cases. The design is ideal for operators pursuing aggressive capacity growth without compromising service quality.
• 2.7x throughput improvement over NCS 5500: By leveraging the new generation of Cisco line cards, organizations experience a substantial performance uplift—nearly triple the throughput compared with the earlier NCS 5500 platform—allowing for more efficient network scaling and enhanced end-user experiences even as traffic patterns shift toward 400GE, 100GE, and 400GE-ready services.
• Optimized for data-center and cloud-scale workloads: Built to support digitalization trends driving global data centers and public/private clouds, the 5700 Line Card enables flexible service chaining, rapid path restoration, and sophisticated traffic engineering. It provides the reliability and feature richness required for hybrid cloud environments, large-scale WANs, and high-velocity service rollouts.
• Programmability, reliability, and efficient operation: The module pairs Cisco’s proven hardware with a software stack that emphasizes programmability, telemetry, and automation. Expect deep buffering, quality-of-service (QoS) capabilities, security features, and robust fault containment—delivering consistent performance with lower operational complexity and improved energy efficiency.

how to install Cisco 5700 Line Card

• Power down or prepare for hot-swapping according to your data center's maintenance procedures. If hot-swapping is supported for your chassis, follow the vendor's guidelines to safely remove and reinsert the card without powering down the system.
• Identify the correct slot in the NCS 5700 chassis designated for 400GE line cards. Ensure the chassis is in a safe state and that field replaceable units (FRUs) are available if needed.
• Remove the blank filler (if present) from the slot and inspect the midplane connectors for cleanliness. Handle the card by its edges to avoid touching copper contacts or connectors.
• Align the line card with the slot and gently insert it until it is firmly seated. Secure the card with the retaining mechanism or screws as required by the chassis design, ensuring a stable, interference-free connection.
• Connect the appropriate 400GE network cables to the line card ports following your topology (e.g., data center spine-leaf, WAN edge, or interconnect links). Use high-quality cables and verified routing to minimize signal integrity issues.
• Power on the chassis if you performed a full power-down, or complete the hot-swap procedure if applicable. Allow the system to complete POST and initialize the new line card. Monitor status indicators and check for any fault LEDs on the module or adjacent components.
• Access the device’s management interface (CLI or GUI) and verify that the line card is recognized. Use commands to confirm port status, hardware inventory, and firmware versions. Perform basic sanity checks for line-rate performance and connectivity.
• Apply the appropriate software image or firmware update if required, ensuring compatibility with the NCS 5700 platform and your deployment requirements. Validate that all features (QoS, EVPN, routing protocols, security features) are operational after the update.
• Document the installation, update inventories, and run extended health checks. Schedule post-install monitoring to verify long-term stability under typical and peak traffic conditions.
