In a midsize data center, IT deploys the EX4300-32F as a leaf switch to connect 32 rack-mounted servers via 1 GbE SFP and four 10 GbE SFP+ uplinks to a spine fabric. Leveraging Virtual Chassis for unified management and Junos OS automation, the deployment achieves low-latency East-West traffic, scalable server expansion, and 30% lower power per port—ensuring predictable performance and simplified operations at rack scale.
A university campus uses the EX4300-32F as its building-level aggregation switch, terminating 1 GbE SFP connections from classroom and lab switches and providing four 10 GbE SFP+ uplinks to the core. With 350 W AC power and redundant Virtual Chassis, the design delivers 10× faster failover, consolidated fiber cabling, and centralized policy enforcement—yielding a 40% reduction in network downtime and seamless bandwidth scaling for digital learning services.
An edge service provider installs the EX4300-32F in colocation sites to deliver business-grade Ethernet to 32 tenant sites over 1 GbE SFP, with four 10 GbE SFP+ links aggregating to the provider backbone. The switch’s compact 350 W AC design, per-port bandwidth control and Junos automation enable SLA-driven service profiles, rapid on-boarding, and 25% lower OpEx—ensuring secure, high-density fiber demarcation and predictable multi-tenant performance.
