WHY CHOOSE THIS PRODUCT?

• Organizations selecting the Juniper EX4100-F-48T typically require a high-density enterprise access switch that balances scalability, operational simplicity, and long-term investment protection. Within the EX4100-F family, it offers substantially higher user density than the 24-port model while avoiding the additional acquisition cost associated with the PoE-enabled EX4100-F-48P where powered endpoints are not required. Dedicated 10GbE uplinks, Virtual Chassis scalability, Junos OS consistency, and cloud-ready management simplify deployment across campus and branch environments while supporting infrastructure modernization, hybrid cloud connectivity, and centralized operations. For procurement teams, the platform provides an effective upgrade path from legacy Gigabit access switches with strong lifecycle value and seamless integration into existing Juniper enterprise networks.
