The Ubiquiti ES-48-500W is a fully managed Layer 2/3 PoE+ switch from the EdgeMAX series, designed for professional network infrastructures. With forty-eight Gigabit RJ45 ports, it serves as a central backbone in environments requiring high-density connectivity such as offices, schools, or medium-sized data centers. Its robust metal chassis and 1U rack-mount form factor enable reliable and tidy installation in server rooms. The product provides an ideal foundation for both standard network devices and those requiring Power over Ethernet support. Its technical strengths lie in high-performance internal architecture and flexible power distribution. With a total non-blocking throughput of 70 Gbps and switching capacity of 140 Gbps, it can process traffic on all ports simultaneously at line rate. Two 10 Gigabit SFP+ and two 1 Gigabit SFP ports provide high-speed uplink connections or integration with fiber optic infrastructure. The 500W total PoE budget offers auto-sensing IEEE 802.3af/at (PoE+) and configurable 24V Passive PoE support across 48 ports, enabling devices such as access points, VoIP phones, and security cameras to receive both data and power over a single cable. Thanks to advanced functionality, the ES-48-500W can be easily used in complex network scenarios. Layer 3 features such as VLAN, link aggregation (LACP), QoS, and static routing allow you to segment your network, prioritize traffic, and perform basic routing operations. Comprehensive management options accessible via a user-friendly web interface and CLI (command line interface) provide network administrators with detailed control. These features make it highly suitable for all professional deployments where a high number of PoE devices and reliable connectivity are critical, such as enterprise office networks, campus environments, or surveillance systems.
