Ubiquiti USW-AGGREGATION UniFi Network Switch
Overview
The Ubiquiti USW-AGGREGATION is a high-performance aggregation switch built for distribution-layer consolidation in medium to large UniFi network deployments. With 160 Gbps switching capacity and 119 Mpps forwarding rate, the USW-AGGREGATION handles real-world traffic from multiple access switches without bottleneck or latency surprises. This throughput matters: if you're pulling data from 10 or more floor-level access switches into a single aggregation point, undersized switching becomes a choke point fast. At this capacity, you're not.
Key Features
- 160 Gbps Switching Capacity, 119 Mpps Forwarding Rate: Handles consolidation of multiple 10G uplinks without degradation. Meaningful for multi-building campuses or service provider networks where you're collapsing dozens of access devices into a single distribution tier.
- 36W Total Power Consumption (including SFP modules): Efficient for an aggregation-class device. In large deployments with dozens of switches, that efficiency compounds into measurable cooling and utility savings. No separate power supply required—internal AC/DC converter draws universal AC (100–240V, 50/60 Hz).
- Compact Form Factor (442 x 120 x 43.7 mm, 2.6 kg without brackets): Fits standard 19-inch racks without wasting cabinet depth. Space matters in co-located data centers and branch office closets.
- SGCC Steel Enclosure with Mounting Brackets: Included steel brackets support rack or shelf mounting. Build quality here is straightforward—not rugged, but solid enough for typical network closet environments.
- VLAN, QoS, and Spanning-Tree Protocol Support: Integrates into existing enterprise network policies without special configuration. Standard Layer 2 switching—no surprises.
- NDAA Section 889 Compliance with International Certifications (CE, FCC, IC, Anatel): NDAA compliance is a genuine advantage for government contractors and defense-sector deployments. Regulatory approval saves time on procurement and audit cycles.
- Operating Temperature Range −5 to 40°C: Suitable for temperature-controlled data centers and edge closets. Not rated for outdoor or extreme cold (like −20°C). Keep it in climate-conditioned spaces.
- UniFi Controller Integration (Ethernet-based Management): Centralized provisioning, firmware updates, and monitoring through UniFi Controller. Reduces operational friction across your switching fabric—one interface for access and aggregation tiers.
Integration & Compatibility
The USW-AGGREGATION is purpose-built for UniFi ecosystems. It pairs natively with UniFi access points, gateways, and other UniFi switches, allowing single-pane management and topology visibility. Out-of-band or in-band management is supported via Ethernet connection to your management network. If you're running a heterogeneous network mixing Ubiquiti and third-party gear, standard ONVIF and VLAN support ensures interoperability—but the real value unlock comes when you consolidate on UniFi across all layers.
When to Choose a Different Model
If your aggregation needs are modest (fewer than 5 access switches feeding into distribution), consider a smaller Ubiquiti switch in the same family—the entry-level models deliver lower throughput at proportionally lower cost. If you require Layer 3 routing or advanced BGP functionality at the aggregation layer, this is a pure Layer 2 device; you'll need a dedicated router or Layer 3 switch. If operating temperature requirements push below −5°C or above 40°C, this device is not suitable.
Installation & Deployment
Mount the unit in a standard rack using included steel brackets, or position on a shelf in a network cabinet. Ensure basic airflow around the device despite its low thermal output (36W is minimal, but still generates some heat). Connect your management Ethernet cable and upstream/downstream switch ports, then power on. Adopt the device into your UniFi Controller via the management interface. Firmware updates and ongoing configuration happen through the Controller—no SSH or CLI necessary for most day-to-day tasks.
Frequently Asked Questions
Q: Is the USW-AGGREGATION NDAA Section 889 compliant?
A: Yes. The device carries explicit NDAA compliance, making it suitable for government and defense contractor procurement without additional vetting.
Q: Can I manage the USW-AGGREGATION without UniFi Controller?
A: The device is designed for UniFi Controller-based management. While basic Ethernet connectivity is possible, you'll lose centralized visibility and firmware update automation without it.
Q: What is the maximum number of access switches the USW-AGGREGATION can handle?
A: With 160 Gbps capacity and 119 Mpps forwarding, you can aggregate many 1G or 10G uplinks without bottleneck. Real limits depend on your traffic patterns and oversubscription tolerance. A rough estimate: 16+ 10G uplinks or 80+ 1G uplinks before saturation—but validate your actual throughput needs.
Q: Does the USW-AGGREGATION support link aggregation (LAG)?
A: Standard Layer 2 aggregation is supported through UniFi Controller configuration. Consult your UniFi controller documentation for LAG setup.
Q: What power supply is included?
A: An internal AC/DC converter is built in. Supply 100–240V AC, 50/60 Hz. No external PSU required.
Q: Can the USW-AGGREGATION be deployed in outdoor or extreme-temperature environments?
A: Operating range is −5 to 40°C. Outdoor or industrial cold/heat applications require a different device.

The USW-AGGREGATION delivers genuine aggregation-tier performance for organizations scaling a UniFi fabric beyond entry-level deployments. At 160 Gbps throughput and 119 Mpps forwarding, it absorbs real-world traffic from multiple access switches without the latency jitter or CPU contention you see in undersized aggregation devices. The 36W power envelope is legitimately efficient for this class—in a 50-switch campus deployment, that efficiency compounds into measurable HVAC load reduction and utility savings. NDAA compliance removes friction on federal and defense procurement cycles.
Technical Highlights:
- 160 Gbps Switching Capacity with 119 Mpps Forwarding: Handles 16 simultaneous 10G uplinks at near-line-rate without performance degradation. Meaningful for multi-building campuses or service provider racks collapsing dozens of access devices into a single distribution tier.
- 36W Total Power (including SFP modules): At scale, this low thermal profile cuts cooling demand and operational cost. A 50-switch deployment using aggregation at multiple tiers can save 2–3 kW in aggregate facility power—real dollars in co-lo or large enterprise data centers.
- NDAA Compliance with CE, FCC, IC, Anatel Certifications: Government and defense buyers skip the compliance risk assessment entirely. Regulatory pre-approval accelerates procurement timelines.
Deployment Considerations:
- Operating range caps at 40°C—not suitable for outdoor cabinets or uncontrolled edge spaces. Keep this device in climate-controlled closets or data centers.
- Pure Layer 2 switching. If you need dynamic routing or BGP at the aggregation layer, this is not the answer; add a dedicated Layer 3 device upstream.
The USW-AGGREGATION is the right pick for multi-site enterprises or campus networks collapsing access-layer traffic into a central distribution point. If you're running a UniFi fabric across 40+ buildings or floors, this device carries the load without bottleneck. If your aggregation role is modest (5–10 access switches), smaller Ubiquiti models deliver adequate performance at lower cost.
