EX3400-24T-DC Use Case
High-Availability Data Center Leaf-Spine Architecture
In a leaf-spine fabric, the EX3400-24T-DC switch provides 24×1/100/1000BASE-T access ports uplinked via 2×40GbE QSFP+ to spine switches. By enabling Virtual Chassis and EVPN-VXLAN, it delivers sub-microsecond latency, active-active MLAG resilience and non-stop forwarding. Outcome: scalable east-west traffic, simplified operations and 99.999% application availability for mission-critical workloads.
Telecom Edge & 5G Fronthaul Aggregation with DC Power Resilience
At the cell-site aggregation point, the DC-powered EX3400-24T-DC switch consolidates multiple 1GbE fronthaul links and up to four 10GbE SFP+ uplinks toward the core. Its wide temperature range, IEEE-compliant timing and redundant DC feed ensure continuous service in telecom shelters. Outcome: low-latency 5G backhaul, simplified tower footprint and carrier-grade uptime under adverse conditions.
Branch-Office SD-WAN Edge with High-Density Uplinks
For distributed enterprises, the EX3400-24T-DC switch serves as the SD-WAN edge in wiring closets, offering 24 Gigabit Ethernet ports for desktops and Wi-Fi APs plus 4×10GbE SFP+ uplinks to cloud routers. Integrated Junos OS automation, Zero Touch Provisioning and Virtual Chassis simplify deployment. Outcome: consistent WAN performance, centralized policy enforcement and OPEX reduction through streamlined management.
