Ubiquiti UISP-S-PRO 24-Port Managed Gigabit PoE Switch
Overview
The Ubiquiti UISP-S-PRO (MPN: UISP-S-PRO) is a 24-port managed Gigabit switch purpose-built for carrier and enterprise backbone deployments where managed switching and distributed power delivery are non-negotiable. Every port supports Gigabit Ethernet with integrated PoE capability, eliminating the need for separate PoE injectors or external power distribution units — a substantial simplification when scaling from dozens to hundreds of endpoints. The switch weighs 11 pounds and is designed for 19-inch rack mounting in telecom POPs, data centers, and enterprise multi-site networks. It integrates directly into managed network switches architectures and the broader Ubiquiti UISP ecosystem, allowing unified management alongside wireless access points, routing, and security appliances.
Key Features
- 24 Gigabit Ports with Full PoE: Every port delivers Gigabit throughput plus PoE power on the same cable. This density matters: instead of managing separate power and data infrastructure, you run a single Ethernet run to each endpoint. For large camera deployments, wireless APs, or subscriber equipment, that reduces cable runs, conduit costs, and installation labor significantly.
- Managed Switching Architecture: CLI and Web GUI interfaces give operators full control over port configuration, VLAN assignment, and traffic policy. You're not locked into a single management paradigm — choose command-line automation for large deployments or the Web GUI for ad-hoc troubleshooting and configuration review.
- VLAN and QoS Support: Segment traffic by device type, service tier, or geography using VLAN tagging. QoS policies let you prioritize critical traffic (voice, real-time video) over bulk downloads or backup traffic — essential in bandwidth-constrained ISP or remote-site scenarios where multiple service classes share the same uplink.
- Port Mirroring for Packet Capture: Mirror any port's traffic to a SPAN port for real-time troubleshooting or packet analysis. This is invaluable when you need to diagnose intermittent connectivity issues or verify that traffic is flowing as intended without breaking the live connection.
- Standard Management Protocols: SNMP support enables integration with existing NOC monitoring platforms and third-party network management tools. You can pull statistics on power consumption, link status, and frame counts from each port — critical visibility when operating large distributed networks.
- Hot-Swappable Port Design: All 24 ports are hot-swappable, meaning you can pull and reconnect endpoints without powering down the switch. In carrier and enterprise environments, this minimizes downtime during equipment swaps or emergency maintenance.
Deployment Contexts
The UISP-S-PRO serves three primary roles. In ISP networks, it functions as a distribution or aggregation switch at carrier POPs, consolidating traffic from multiple remote sites before backhaul to core infrastructure. In enterprise campuses, it provides the managed switching and PoE distribution backbone for converged infrastructure — combining IP cameras, door access controllers, wireless APs, and VoIP endpoints on a single physical layer. In multi-site warehouse or automation deployments, it centralizes power and data for mobile computers, printers, scanners, and conveyor control systems, with VLAN segmentation to isolate operational networks from guest or management traffic.
Integration and Configuration
Installation begins with standard 19-inch rack mounting and connectivity to upstream routers or core switches via one or more Gigabit ports. Power and network feeds must be established before initial configuration. The Web GUI or CLI interface is reachable immediately after connectivity, allowing you to assign VLANs, set port speeds, establish PoE power budgets for each port, and configure SNMP traps and syslog forwarding. The UISP-S-PRO integrates with network video recorders and IP cameras that rely on PoE; it also pairs with access control systems and wireless networks requiring distributed power delivery. For IT architects planning PoE power distribution strategies, the UISP-S-PRO's 24-port density simplifies capacity planning and reduces the number of switches required at the aggregation layer.
Installation Notes
The switch is ready for deployment in new network builds or capacity expansions with no firmware updates required in most environments. Adequate ventilation around the unit is necessary to maintain thermal stability during sustained traffic loads. All 24 Gigabit ports are populated and functional; no module swaps or optional uplinks are needed. PoE power distribution requires connection to a compatible upstream power source capable of sustaining the total wattage draw of connected endpoints — plan accordingly during initial capacity assessment.
Frequently Asked Questions
Q: Does every port on the UISP-S-PRO support PoE power?
A: Yes. All 24 Gigabit ports deliver both data and PoE power simultaneously, eliminating the need for separate PoE injectors or power distribution units.
Q: Can I manage the UISP-S-PRO remotely?
A: Yes, via Web GUI or CLI over the network. SNMP is also supported for integration with third-party NOC monitoring platforms and Ubiquiti's native UISP controller software.
Q: Is the UISP-S-PRO suitable for small deployments?
A: It's engineered for mid-to-large scale networks — ISP POPs, enterprise campuses, and multi-site warehouse operations. For small offices or single-location deployments with fewer than 12 endpoints, a smaller unmanaged or lite-managed switch may be more cost-effective.
Q: What happens if I exceed the PoE power budget on the switch?
A: Excessive draw on individual ports or the aggregate power bus will trigger port shut-down or power cycling to protect the supply. Configure per-port power limits and monitor consumption via the management interface to stay within budget.
Q: Does the UISP-S-PRO support redundant uplinks?
A: Yes. You can assign multiple ports as uplinks to upstream routers or core switches and configure link aggregation (LAG) or spanning tree protocols to provide failover and load balancing.
Q: What is the typical power consumption of the UISP-S-PRO?
A: Power draw depends on connected endpoint load. Consult the datasheet for no-load baseline and per-port PoE budget; then calculate aggregate draw based on the wattage of each connected device.

The UISP-S-PRO delivers exactly what carrier and enterprise network architects need at the aggregation layer: 24 managed Gigabit ports with PoE on every single port. This density eliminates the complexity of separate power infrastructure — a real advantage when you're deploying dozens of cameras, wireless APs, or subscriber gear across a POP or campus. The CLI and Web GUI management paths give operators flexibility, and SNMP integration hooks into existing NOC workflows without friction.
Technical Highlights:
- 24 Gigabit PoE Ports: All ports support simultaneous data and power delivery. This means single-cable runs to each endpoint, lower installation labor, and no separate PoE injector sprawl — a cost and complexity win at scale.
- Managed Architecture with VLAN and QoS: Segment traffic by service type or geography using VLAN tagging; prioritize critical flows (voice, real-time video) via QoS policies. In bandwidth-constrained ISP or remote-site scenarios, this isolation is non-negotiable.
- Port Mirroring and SNMP: Mirror traffic to a SPAN port for packet-level troubleshooting. SNMP pull gives you power consumption, link status, and frame counts per port — critical visibility in distributed networks with dozens of active sites.
Deployment Considerations:
- Calculate aggregate PoE power draw before connecting all endpoints. Exceeding the power budget on the supply side will trigger port shut-down or cycling — monitor and configure per-port limits via the management interface to avoid surprises.
- The UISP-S-PRO is built for mid-to-large deployments. If you're managing fewer than 12 endpoints in a single location, a smaller unmanaged or lite-managed switch will be more cost-appropriate.
Deploy the UISP-S-PRO as your aggregation spine in ISP multi-site networks, carrier POPs, or enterprise campuses where managed switching, distributed PoE, and consolidated visibility are critical. The combination of 24 managed ports and zero separate power boxes simplifies operations and scales cleanly as your network grows.
