The Ubiquiti UISP-S-Pro is a high-performance PoE switch designed specifically for wireless internet service providers (WISPs) and professional network infrastructures. It offers flexible and high-speed connectivity with 24 Gigabit Ethernet RJ45 ports and 4 10 Gigabit SFP+ fiber uplink ports. It features 27V passive PoE support on 16 ports to power radio devices and access points. This device can be easily managed via the centralized UISP application and is built with a robust metal and polycarbonate enclosure for reliable operation in harsh environmental conditions. The switch's technical strengths include a switching capacity of 128 Gbps and a total non-blocking throughput of 64 Gbps, ensuring high performance and low latency even under heavy network traffic. With a total PoE budget of 220W, it can power multiple devices simultaneously, while the internal 250W power supply and wide voltage range (100-240V AC) guarantee compatibility with different electrical infrastructures. Additionally, the 1.3-inch touchscreen LCD on the front panel provides real-time device status and network statistics for quick monitoring and setup. The Ubiquiti UISP-S-Pro is ideal for outdoor WISP deployments such as towers and base stations, security camera systems, and industrial networks. The passive PoE feature is directly compatible with Ubiquiti's outdoor radio devices and access points, eliminating the need for separate PoE injectors. The four SFP+ ports provide an excellent foundation for high-speed backbone connections via fiber optic cabling or stacking with other switches. The wide operating temperature range of -10°C to 50°C ensures stability in non-standard environments.
