Ubiquiti UISP Switch Plus (UISP-S-PLUS)
The Ubiquiti UISP Switch Plus is a high-capacity Layer 2 switch purpose-built for Wireless Internet Service Providers (WISPs) and micro-pop deployments. Designed to sit at the tower base or within a central communications hub, it bridges high-speed fibre backhaul with multi-gigabit wireless distribution hardware.
With a total non-blocking switching capacity of 100 Gbps, this unit handles heavy throughput loads without bottlenecking local traffic.
Core Networking Capabilities
-
Multi-Gigabit Ethernet Access: Equipped with four 2.5 GbE RJ45 ports. This faster standard prevents link saturation when feeding high-throughput sector antennas and point-to-point wireless bridges.
-
10G Fibre Uplinks: Features four 10G SFP+ ports. These allow for massive bandwidth routing back to your core network, daisy-chaining multiple switches, or connecting directly to high-speed incoming fibre lines.
-
Centralised WISP Management: Fully monitored via the Ubiquiti UISP application. This platform gives you a single interface to manage customer queues, monitor link metrics, configure VLANs, and track power consumption across your entire distribution site.
Power Over Ethernet & Redundancy
The UISP-S-PLUS features a substantial 160W PoE budget using the included mains power supply. It delivers 27V Passive PoE, which matches the native power requirements of standard Ubiquiti airMAX, LTU, and Wave deployment hardware.
| Port Range | PoE Type | Pair Mode | Max Wattage Per Port |
| Ports 1 to 4 | 27V Passive PoE | 2-Pair Mode (pins 4, 5+ / 7, 8-) | 20 Watts |
| Ports 1 to 4 | 27V Passive PoE | 4-Pair Mode (pins 1, 2, 4, 5+ / 3, 6, 7, 8-) | 40 Watts |
Power Redundancy Warning: To protect against mains power failure on critical infrastructure sites, the switch includes a built-in Power TransPort DC input. This allows you to connect an external 27V DC auxiliary power system, ensuring your wireless distribution stays online during a local power cut.

Deployment & Mounting Layouts
The unit's form factor allows it to adapt to whatever site layout you encounter:
-
Desktop Setup: Rubber feet are included for flat placement inside communications cabinets or shelves.
-
Wall / Rack Mounting: Brackets are provided to secure the chassis flush against a solid wall or integrated into a standard 19-inch equipment rack (occupying 1U of space).
-
Outdoor Tower Use: While the internal chassis is steel, you can deploy this switch directly on an exposed mast or tower by housing it within the optional weatherproofing UISP Box Plus enclosure.
