Juniper EX4300 Ethernet Switch vs Ubiquiti UniFi Switch 48 PoE (US‑48‑500W)

The Juniper EX4300 is a compact, fixed-configuration Ethernet switch designed for enterprise and data center environments. It delivers high-density 10/100/1000BASE‑T ports with optional 10GbE uplinks, supporting Virtual Chassis technology for simplified management and scalability. Built on Junos OS, the EX4300 offers advanced Layer 2 and Layer 3 features, including Virtual Router Redundancy Protocol (VRRP), MACsec encryption, and extensive automation via NETCONF and REST APIs. Its low power consumption and fanless options make it ideal for high‑density deployments.

The UniFi Switch 48 PoE delivers 48 Gigabit Ethernet ports with full PoE+ support, providing up to 500 W of power for cameras, access points, and other devices. It also includes two 1 GbE SFP ports and two 10 GbE SFP+ ports for high‑speed uplinks and fiber connectivity. Managed through the UniFi Network Controller, the switch offers Layer‑2 features such as VLANs, link aggregation, and port mirroring, making it ideal for enterprise and SMB networks that need reliable, scalable PoE infrastructure.
