Juniper EX4300‑48T 48‑Port Gigabit Ethernet Switch

The Juniper EX4300‑48T is a high‑performance, fixed‑configuration Layer 2/Layer 3 Ethernet switch ideal for enterprise access, campus aggregation, and data center top‑of‑rack connectivity. It provides 48 built‑in 10/100/1000BASE‑T RJ‑45 ports for standard Gigabit Ethernet access and four built‑in 40 Gbps QSFP+ uplinks that can be utilized as network or Virtual Chassis ports (VCPs). Designed for flexibility, the unit supports optional uplink modules like 10 GbE or 40 GbE interfaces for expanded connectivity options. Running Juniper’s Junos OS, the EX4300 delivers advanced switching, routing, security, automation, and telemetry features with carrier‑class resiliency — including redundant power and fans, graceful Routing Engine switchover (GRES), and nonstop bridging/routing in Virtual Chassis configurations. With up to 320 Gbps backplane capacity and 369 Mpps throughput, it supports scalable, resilient performance in demanding enterprise and campus environments.
