Ubiquiti UniFi USW-Enterprise-24 PoE Gen1 – 24-Port Layer 3 PoE+ Switch, 400 W Budget

The Ubiquiti UniFi USW-Enterprise-24 PoE Gen1 is a powerful, rack-mountable Layer 3 switch designed for enterprise deployments requiring robust PoE+ support and advanced switching capabilities. It features 24 PoE+ ports (divided equally between 1 GbE and 2.5 GbE) and delivers a total PoE budget of 400 W, enabling reliable powering of numerous access points, cameras, or other devices without external injectors. This switch is ideal for midsize networks, branch offices, or core wiring closets that demand both data throughput and flexible power delivery.

Built for performance, the switch offers a switching capacity of 124 Gbps, a forwarding rate of 92 Mpps, and full Layer 3 functionality for routing, VLANs, and inter-VLAN traffic. Designed for dense environments, it supports Pro AV profiles, QoS, LACP, STP/RSTP, ACLs, DHCP relay, static routing, and more. A touchscreen LCM display provides at-a-glance status, while dual power input and redundancy features ensure continuous operation.
