Ubiquiti USW-PRO-HD-24 UniFi Network Switch
Overview
The Ubiquiti USW-PRO-HD-24 is a 1U rack-mount managed switch designed for multi-building campuses and medium-to-large surveillance deployments. This model delivers 24 ports of 2.5GbE connectivity paired with dual 10GbE uplinks and four SFP+ ports, totaling 230 Gbps switching capacity and 115 Gbps non-blocking throughput. The combination of port density and uplink bandwidth directly addresses the challenge of consolidating high-bitrate video streams, dense access point clusters, and IoT devices into a single switching tier without forcing gigabit-only compromises that create bottlenecks during simultaneous camera recording.
Key Features
- 24 x 2.5GbE ports: Unlike gigabit-only switches, each port supports up to 2.5 Gbps, allowing individual IP cameras or access points to push beyond 1 Gbps without saturating the switch fabric. Particularly useful when deploying high-bitrate 4K or multi-stream surveillance cameras on a single access switch.
- Dual 10GbE + four SFP+ uplinks: Two 10GbE Ethernet ports and four SFP+ ports (supporting both Ethernet and fiber) give you genuine flexibility in how you connect to core infrastructure. No vendor lock-in to proprietary uplink modules—use 10GBASE-T copper, 10GBASE-SR/LR fiber, or mix and match depending on your backbone topology.
- 115 Gbps non-blocking throughput: Every port can transmit simultaneously at full line rate without packet loss. In practice, this means you can record from all 24 attached cameras at maximum bitrate and simultaneously push data upstream without internal congestion—a hard requirement for 24/7 surveillance operations.
- 171.12 Mpps forwarding rate: Forward millions of packets per second with minimal latency. In low-latency environments (e.g., real-time video analytics or network-attached storage), this keeps frame delivery consistent.
- VLAN support up to 1,000 domains: Segment traffic by security tier (cameras on one VLAN, management on another, guest IoT on a third). Simplifies auditing and isolates a compromised device from affecting the entire network.
- 60W total power consumption: Integrated AC/DC power supply (100–240V universal input) uses just 60W under normal operation. No external power supply clutter, and low thermal output means less burden on cooling systems in utility closets or outdoor enclosures.
- −5 to 40°C operating range: While rated for outdoor utility enclosures, this assumes environmental conditioning (shed, conditioned cabinet). Do not mount this switch in direct sunlight or unheated spaces in winter climates without additional protection.
- Standard 19-inch rack mount, 1U: Weighs 4.2 kg and fits in any standard rack. No custom brackets needed, and the single-rack-unit footprint minimizes space utilization.
Integration & Compatibility
The USW-PRO-HD-24 integrates with the UniFi ecosystem via direct Ethernet connection to a UniFi Dream Machine or UniFi Network Controller (cloud or self-hosted). Management occurs entirely through the UniFi UI—no command-line configuration required unless you need advanced static routing or policy routing, both of which are supported. The switch advertises 802.1Q VLAN, link aggregation (802.3ad), QoS with traffic prioritization, and NDAA Section 889 compliance, making it suitable for regulated environments and federal procurements. CE, FCC, IC, and Anatel certifications cover North American and international deployments.
Deployment Scenarios
This switch fits best as an access-layer device in a multi-building campus where you're consolidating 20–50 IP IP cameras, outdoor mesh access points, or dense indoor AP clusters into a single physical location. In a typical warehouse or office-park scenario, the USW-PRO-HD-24 sits in a main communications closet, connects 24 surveillance cameras or access points via 2.5GbE, and backhauls video and management traffic via a 10GbE uplink to your core switch or NVR appliance. The four SFP+ ports provide a pathway to fiber-run backbone links if your main distribution frame is in a separate building 100+ meters away. Educational institutions, healthcare facilities, and light-manufacturing sites with distributed surveillance derive immediate benefit from the port count and uplink capacity without over-provisioning.
Cable and Fiber Considerations
2.5GbE over copper requires Cat6A cabling and respects the 100-meter IEEE 802.3bz distance limit. Verify SFP+ module compatibility with Ubiquiti if using third-party transceiver optics—some non-Ubiquiti modules have firmware compatibility issues. For straightforward deployments, stick to the documented Ubiquiti SFP+ options or the dual 10GbE ports with standard 10GBASE-T switches.
Frequently Asked Questions
Q: Is the USW-PRO-HD-24 NDAA Section 889 compliant?
A: Yes. The USW-PRO-HD-24 carries NDAA compliance and is suitable for federal and state procurement where NDAA restrictions apply.
Q: Can I mix the USW-PRO-HD-24 with other Ubiquiti switches in the same network?
A: Yes. The USW-PRO-HD-24 works alongside other UniFi switches (e.g., USW-PRO-24, USW-Aggregation) when managed by the same UniFi Controller. They stack logically via link aggregation if you need to expand capacity or provide redundancy.
Q: What is the maximum cable run length for 2.5GbE connections from the USW-PRO-HD-24 to an IP camera?
A: Standard 802.3bz supports 100 meters (328 feet) over Cat6A cabling. Beyond 100 meters, use fiber SFP+ connections on the USW-PRO-HD-24 or step down to gigabit switches closer to the remote location.
Q: Does the USW-PRO-HD-24 support Power over Ethernet (PoE) for cameras?
A: No. The USW-PRO-HD-24 is a managed Ethernet switch without integrated PoE. You must pair it with a PoE injector or PoE-enabled access switch upstream or use separate PoE adapters at the camera end.
Q: What happens if I lose connectivity to the UniFi Controller?
A: The USW-PRO-HD-24 continues to forward traffic (L2 switching) at line rate even if the controller is unreachable. Configuration changes and advanced features (QoS, VLAN assignment) require the controller, but basic connectivity persists. Firmware updates and policy pushes are queued and applied once the controller returns online.
Q: Can I use PoE+ or PoE++ switches to power devices on the same uplink as the USW-PRO-HD-24?
A: Yes. The USW-PRO-HD-24 is compatible with any PoE-capable switch on the uplink side. Your upstream device can inject power while the USW-PRO-HD-24 forwards traffic.

The USW-PRO-HD-24 solves a real sizing problem: gigabit switches force you into switch sprawl when you're deploying 20+ cameras, and datacenter-class 10GbE core switches are overkill for an access layer. This unit sits in the middle with genuine 2.5GbE density on all 24 ports—meaning each camera can push 2+ Gbps without choking the backhaul. The non-blocking 115 Gbps throughput is the clincher: all 24 ports saturated simultaneously won't cause internal packet loss.
Technical Highlights:
- 24 x 2.5GbE + dual 10GbE uplinks: Eliminates the gigabit bottleneck that plagues single-switch deployments. A typical 4K camera pulling 30–50 Mbps no longer shares bandwidth with 23 other devices on a 1 Gbps pipe.
- 115 Gbps non-blocking throughput: All 24 ports can transmit at line rate simultaneously. In 24/7 surveillance, this means zero internal congestion during peak recording hours—no hidden packet drops that you discover weeks later during forensic review.
- VLAN support up to 1,000 domains: Segment your surveillance VLAN from your management and guest networks with zero performance penalty. Limits lateral movement if a camera is compromised.
- 60W total draw, internal PSU: Low power budget simplifies placement in outdoor utility enclosures or equipment racks with limited power distribution. Easier to run off battery backup or solar in remote sites.
Deployment Considerations:
- This unit is UniFi-centric: if you're running a heterogeneous network (Mikrotik core, Ubiquiti edge), the USW-PRO-HD-24 plays well via standard 802.1Q VLANs, but you lose the single-pane-of-glass UniFi management benefits.
- No integrated PoE: your cameras and access points must source power from a separate PoE switch, injector, or wall adapter. Plan your power architecture separately—don't assume power and data come from the same device.
- 2.5GbE requires Cat6A cabling and respects 100-meter distance limits. If your camera runs exceed that, budget for fiber SFP+ runs (more expensive but future-proof).
Deploy the USW-PRO-HD-24 as your access-layer switch in any campus with 20+ IP cameras, a large outdoor mesh network, or mixed surveillance and IoT deployments. It eliminates the false choice between gigabit switches (cheap, limited) and datacenter gear (expensive, over-featured). For a mid-market warehouse, office park, or healthcare campus, this is the right-sized access switch.
