Ubiquiti USW-24-POE 24-Port Managed PoE Switch
Overview
The Ubiquiti USW-24-POE is a 24-port managed Gigabit Ethernet switch purpose-built for enterprise and mid-market deployments where power and data must travel a single cable run. All 24 ports operate at 1 Gigabit speed with integrated Power over Ethernet (PoE) delivery — a combined 95W PoE budget distributed across connected devices. This means you can power IP cameras, wireless access points, and network-attached sensors from the switch itself, eliminating dedicated power infrastructure for each device. The USW-24-POE delivers 52 Gbps switching capacity with 26 Gbps non-blocking throughput and a 39 Mpps forwarding rate, so full line-rate data flows across all 24 ports simultaneously without congestion or dropped packets — a real advantage in dense multi-camera surveillance deployments.
Key Features
- 95W PoE Budget: Sufficient to power a typical mix of 8–12 surveillance cameras plus one or two wireless access points simultaneously. This is the constraint to plan around — if you need 24 full-draw devices, you'll need a larger switch or multiple units. Budget 13W per full-featured camera (IR, pan-tilt) and 7–10W per access point.
- 52 Gbps Switching Capacity: Handles traffic from dozens of cameras and endpoints without backplane saturation. The 26 Gbps non-blocking throughput means every port can push data at line rate without competing for bandwidth.
- Non-Blocking Architecture: Full-rate forwarding across all 24 ports eliminates the bottleneck common in oversubscribed access switches — a real factor when recording 24/7 from multiple high-bitrate cameras.
- Up to 1,000 VLANs: Logically separate camera traffic, guest networks, operational systems, and IoT sensors on a single physical switch. Critical for security isolation in mixed-use or multi-tenant deployments without additional hardware.
- UniFi Controller Integration: Centralized management via the UniFi network management platform — real-time port monitoring, traffic statistics, and PoE allocation visibility. Deploy and monitor the USW-24-POE alongside Ubiquiti IP cameras and access points from a single dashboard.
- Universal AC Input (100–240V, 50/60 Hz) with 120W Internal Supply: No external power adapter required; 25W typical consumption means efficient 24/7 operation. Fits standard 19-inch racks with included SGCC steel brackets.
- Operating Range –5°C to 40°C: Deployable in temperature-controlled network closets, MDFs, and branch locations. Not rated for outdoor or uncontrolled environments.
- NDAA Section 889 and TAA Compliance, CE/FCC/IC/Anatel Certified: Meets federal procurement standards for government and critical infrastructure projects.
Integration and Compatibility
The USW-24-POE integrates seamlessly into UniFi-managed environments, communicating with UniFi Controllers for real-time configuration and monitoring. VLAN tagging and trunk support enable multi-network isolation from a single physical unit. Direct web access allows standalone operation without a controller. For PoE infrastructure planning, confirm your total device draw against the 95W budget — undersizing here is the leading cause of intermittent camera or access-point failures. Non-blocking architecture ensures that simultaneous high-bitrate camera streams don't starve each other or interfere with management traffic.
Installation Notes
Mount in a standard 19-inch rack using supplied brackets. Connect AC power to the universal-input supply; connect a management Ethernet cable or enable DHCP for automatic IP assignment. All 24 ports are operational immediately upon power-on. PoE allocation and port configuration are managed via the UniFi interface or direct web access. Ensure adequate airflow, particularly in warm environments approaching the 40°C ceiling.
When to Choose a Different Model
If your PoE budget exceeds 95W (e.g., more than 8–10 simultaneous high-draw cameras), consider the USW-48-POE (48 ports, higher PoE capacity) or deploy multiple USW-24-POE units in a daisy-chain topology. For non-PoE or low-PoE device deployments, evaluate the USW-24 (standard Gigabit switch without PoE delivery) to reduce cost. If you require 10 Gigabit uplink ports for multi-switch stacking or high-volume recording appliances, step up to the USW-PRO series.
Frequently Asked Questions
Q: Can I power 24 cameras simultaneously on the USW-24-POE?
A: No. The 95W PoE budget supports 8–12 full-featured surveillance cameras plus optional access points, depending on per-device wattage. Plan for 13W per IR-enabled camera and 7–10W per access point. Exceeding the budget causes PoE shutdown on affected ports.
Q: Is the USW-24-POE compatible with non-Ubiquiti cameras and access points?
A: Yes. The switch delivers standard 802.3af/at PoE to any compatible device. UniFi Controller integration is limited to Ubiquiti hardware, but the USW-24-POE operates as a standard managed Gigabit switch with any ONVIF or IP-based camera and access point.
Q: Does the USW-24-POE support daisy-chaining or stacking?
A: The USW-24-POE does not support hardware stacking (no dedicated stack ports). Multiple units can be connected via standard Gigabit ports and managed independently or via UniFi Controller for unified visibility and configuration.
Q: What is the warranty on the USW-24-POE?
A: Ubiquiti offers a standard 1-year limited hardware warranty from the date of purchase. Extended warranty options may be available through authorized integrators.
Q: Can I wall-mount the USW-24-POE instead of rack-mounting?
A: The USW-24-POE is designed for 19-inch rack installation. Wall mounting is not supported by the standard bracket set; custom mounting would require third-party hardware and is not recommended due to cooling and service access considerations.
Q: Does the USW-24-POE support VLAN tagging for traffic isolation?
A: Yes. The switch supports up to 1,000 VLANs and 802.1Q tagging, enabling you to isolate camera networks, guest traffic, and operational systems on a single physical unit without additional switches.

The USW-24-POE remains a workhorse for small-to-medium PoE deployments. The 95W PoE budget is moderate — it won't power 24 full-draw devices simultaneously — but it's precisely calibrated for the typical mix of low-power access points (7–10W), standard fixed cameras (8–12W), and a few higher-draw PTZ units (13–15W). If you plan correctly, this switch eliminates cable clutter and UPS complexity in branch offices and retail locations.
Technical Highlights:
- 52 Gbps Switching Capacity with 26 Gbps Non-Blocking Throughput: Every port can forward data at full Gigabit line rate simultaneously. This matters: on dense multi-camera sites (8–12 cameras at 4–6 Mbps each), the non-blocking architecture ensures no inter-port packet loss or latency spikes that would cause frame drops or delay in alarm events.
- 95W PoE Budget Distributed Across 24 Ports: No port has per-port limits — allocation is dynamic via firmware. A 12W camera consumes 12W; an 8W access point consumes 8W. Budget exhaustion triggers graceful shutdown on the oldest device, not a cascade failure. This is predictable behavior.
- 1,000 VLAN Support with 802.1Q Tagging: Isolate camera subnets from guest WiFi and administrative traffic on a single physical switch. Reduces hardware footprint and simplifies compliance segregation in regulated environments (healthcare, hospitality).
- NDAA/TAA Compliance: Clears federal procurement gates without exception letters — pre-positioned for government contracts and critical infrastructure RFQs.
Deployment Considerations:
- The 95W Budget Is a Hard Ceiling: Document your per-device wattage in advance. A single miscalculation (e.g., assuming a PTZ draws 8W when it draws 18W) causes intermittent PoE faults that surface only under peak load or thermal stress — difficult to troubleshoot. Size conservatively: budget 13W per camera, 10W per access point, then back off by 20%.
- No Hardware Stacking: If you need more ports or PoE capacity, you deploy a second USW-24-POE and link them via standard Gigabit trunk. This is simple, but it adds a single point of failure between units. Plan upstream redundancy (dual uplinks to core) if availability is critical.
- Temperature Ceiling of 40°C: The switch is indoor-rated. In hot climates or poorly cooled closets, thermal throttling or early component fatigue becomes a risk. Ensure 6+ inches of clearance above and below the unit.
Best-fit scenario: retail or hospitality chain with 2–3 stores, each site has 8–10 surveillance cameras plus 2–3 WiFi access points, and a dedicated network closet with climate control. The USW-24-POE eliminates per-camera PoE injectors, centralizes management via UniFi, and clears federal procurement standards without complexity. If you need more than 12 simultaneous PoE devices per site, step up to the USW-48-POE or deploy dual USW-24-POE units with careful load balancing.
