T4K-12XGE-FPC5-UPG Use Case
Data Center Spine Upgrade with T4K-12XGE-FPC5-UPG Kit
In a hyperscale data center, network architects deploy the T4K-12XGE-FPC5-UPG-Upgrade Kit for T1600 or T640 to expand spine switch capacity by adding 12x10GbE SFP+ ports via PF-12XGE-SFPP and leveraging the T4000-FPC5-3D forwarding card. Dual RE-DUO-C1800-16G-S route engines, five SIB-I-T4000-S fabric blades, redundant PWR-T-6-60-DC-S power supplies and hot-swap FANTRAY-T4000-S and FAN-REAR-TXP-LCC-S fans ensure 6 Tbps throughput, sub-400 µs latency, and 99.999% uptime. Outcome: seamless east-west traffic scaling, elimination of bandwidth bottlenecks, and optimized data flow for mission-critical applications.
Enterprise Campus Core Resiliency Boost with T4K-12XGE-FPC5-UPG Kit
A multinational enterprise modernizes its campus core network on a T1600 chassis by installing the T4K-12XGE-FPC5-UPG-Upgrade Kit for T1600 or T640. The bundle’s PF-12XGE-SFPP modules deliver 12 additional 10GbE uplinks for IP surveillance, VoIP, and Wi-Fi 6 backhaul, while the T4000-FPC5-3D card accelerates packet forwarding. Dual CB-LCC-S carriers, two FANTRAY-T4000-S assemblies, FAN-REAR-TXP-LCC-S cooling modules, and CRAFT-T-SERIES-S console management enable non-stop operation. Outcome: 40% higher port density, fault-tolerant cooling and power, simplified hot-swap maintenance, and enhanced network security.
Service Provider Metro Edge Aggregation Scaling
A regional service provider upgrades its metro edge on a T640 switch using the T4K-12XGE-FPC5-UPG-Upgrade Kit to accelerate business Ethernet and DSL service rollouts. The solution adds 12x10GbE SFP+ ports via PF-12XGE-SFPP, implements dual RE-DUO-C1800-16G-S engines for OSPF/MPLS routing, and installs five SIB-I-T4000-S fabric blades for 6 Tbps switching capacity. Redundant PWR-T-6-60-DC-S power modules and hot-swappable FANTRAY-T4000-S fans ensure sub-50 ms failover. Outcome: rapid service provisioning, 30% reduction in OPEX, and scalable bandwidth growth with carrier-grade reliability.
