Ubiquiti UISP Switch Plus
The Ubiquiti UISP Switch Plus is designed for ISP applications as a 2.5 GbE PoE switch. Its features include (4) 2.5 GbE RJ45 ports with 27V passive PoE output, (4) 10G SFP+ ports, and 160W (27V) total PoE availability. Port isolation, speed limiting, and DHCP snooping functionality are also included. It has the option for DC redundancy with a Power TransPort™ input, and can be mounted on a desk, wall, 1U rack, or outdoor** (**with the UISP Box Plus (sold separately)).

FAQs
Q1: What is the UISP‑S‑Plus used for?
A: The UISP‑S‑Plus is a managed network switch designed for ISP or small‑business deployments — it combines multi‑gigabit ports, fibre uplink options, and substantial PoE output to power downstream devices like access‑points or CPE.
Q2: What ports and connectivity does the UISP‑S‑Plus offer?
A: It provides 4 × 1/2.5 GbE RJ45 LAN ports (with PoE output) and 4 × 1/10 Gbps SFP+ ports for fibre or high‑speed uplinks.
Q3: What are the PoE output capabilities and total power budget?
A: The switch supports passive 27 V PoE across the four RJ45 ports, with a total PoE budget of 160 W. Individual ports can output up to 20 W (2‑pair mode) or up to 40 W (4‑pair mode) depending on configuration.
Q4: What performance specs (throughput, switching capacity) does UISP‑S‑Plus deliver?
A: It delivers up to 50 Gbps non‑blocking throughput, a 100 Gbps switching capacity, and a packet forwarding rate of about 74.4 million packets per second (Mpps) — enough for multi‑device, high‑bandwidth networks.
Q5: What power options and deployment contexts is UISP‑S‑Plus suited for?
A: It can be powered by the included AC/DC adapter or via a 27 V DC input (for DC‑powered deployments), and supports desktop, wall, or rack‑mounting, making it versatile for small‑offices, PoE‑powered installations, or compact ISP setups.
