The Juniper Networks EX3400-48P is a Refurbished enterprise access layer switch built for demanding wired network environments where both port density and Power over Ethernet are essential. With 48 PoE+ enabled ports, this switch can simultaneously power and connect a wide range of endpoint devices including IP phones, wireless access points, IP cameras, and other 802.3at-compatible equipment.Beyond its access-layer port count, the EX3400-48P provides four 10GbE SFP+ uplink ports and two 40GbE QSFP+ uplink ports, giving network administrators the flexibility to connect to aggregation or core layers at high speeds without creating bottlenecks. This uplink architecture makes the EX3400-48P a strong fit for modern, high-throughput network designs.
As part of Juniper's EX3400 Series, this switch runs Junos OS, Juniper's proven network operating system, which provides a consistent CLI experience, robust automation support, and enterprise-grade feature sets including Layer 2 and Layer 3 functionality.
Purchased as a Refurbished unit from WhaleyComm, this switch undergoes inspection and testing to ensure reliable operation, delivering enterprise-grade capability at a fraction of the new price. It is an ideal choice for IT teams looking to expand or refresh their access layer infrastructure while managing capital expenditure budgets effectively.
