Ubiquiti UISP-S-PLUS UISP Management Device

Ubiquiti UISP-S-PLUS UISP Management Device

Overview

The Ubiquiti UISP-S-PLUS (MPN: UISP-S-PLUS) is a centralized management and PoE power distribution device designed for mid-to-large scale UISP deployments. It functions as both a management hub and intelligent power supply, consolidating control and power delivery across distributed infrastructure while supporting mixed copper and fiber connectivity. The device delivers 160W of total PoE budget at 27V passive, enabling flexible per-port power allocation across both 2-pair and 4-pair configurations.

Key Features

The UISP-S-PLUS combines four 2.5 GbE RJ45 ports with four 10G SFP+ ports, providing layered bandwidth for management traffic, device control, and high-speed uplinks. Its 160W power budget accommodates 20W per port on 2-pair PoE or 40W per port on 4-pair configurations, allowing operators to power mixed endpoint densities without additional power supplies. Management is accessible via standalone local web interface or direct UISP Application integration, enabling both isolated and cloud-connected operational models. The device supports multiple form factors—desk, wall, 1U rack, and outdoor mounting—adapting to various network closet and field deployment environments.

Deployment Scenarios

The UISP-S-PLUS serves as a regional aggregation point in multi-site UISP networks, concentrating management and power for access points, switches, and wireless uplinks. In distributed antenna systems, it provides centralized power and control to remote radio heads. For wireless backhaul networks, the combination of 2.5 GbE copper and 10G SFP+ uplinks supports both standard throughput management and high-capacity fiber interconnects without requiring separate power or control infrastructure.

Network Integration

The device integrates seamlessly into existing UISP ecosystems through native application support while remaining functional as a standalone managed device. The four 10G SFP+ ports support both direct fiber connections and media converters, enabling integration with legacy copper uplinks or long-distance fiber runs. The 2.5 GbE ports handle endpoint connections and management traffic, reducing congestion on higher-capacity uplinks.

Installation Notes

The UISP-S-PLUS weighs 8.6 lbs and operates on 27V passive PoE input, requiring compatible source power from upstream equipment or external PSU. Its flexible mounting options allow installation in constrained spaces, while the passive 27V architecture eliminates proprietary power connector dependencies. Setup begins through the local web interface, with optional UISP Application enrollment for centralized multi-device management.
