Ubiquiti USW-PRO-XG-AGGREGATION 32-Port 25G Aggregation Switch
Overview
The Ubiquiti USW-PRO-XG-AGGREGATION is a 1U rack-mount aggregation switch engineered for high-capacity network backbones in enterprise and campus deployments. With 32 ports of 25G SFP28 connectivity, this switch delivers 1.6 Tbps of switching fabric capacity—meaning you can move massive volumes of data between buildings, data centers, or distribution layers without creating bottlenecks. The 800 Gbps non-blocking throughput ensures that traffic from multiple access switches or server interconnects doesn't queue up waiting for bandwidth. At 1.2 billion packets per second (Bpps), the forwarding rate handles mixed frame sizes without performance degradation, critical in real-world networks where traffic patterns are unpredictable.
Key Features
- 32-port 25G SFP28 layout: Each port supports 25G, 10G, and 1G line rates—no speed negotiation penalties. If you're aggregating from eight 10G access switches, each will see full 10G throughput to the backbone without oversubscription. Future-proofs toward 25G adoption without forcing a forklift upgrade.
- 1.6 Tbps switching fabric, 800 Gbps non-blocking: Every port pair can transmit simultaneously at line rate. Real-world benefit: east-west server-to-server traffic, campus inter-building fiber runs, and multi-location failover scenarios won't be constrained by the switch itself—your links will be the limiter, not the hardware.
- VLAN support up to 1,000: Granular network segmentation and multi-tenant isolation without VLAN compression tricks. Scales for mid-to-large campuses and service provider backbones where separate broadcast domains are non-negotiable.
- Universal 100–240V AC input, 200W power supply: A 200W envelope at peak load is modest for a 32-port 25G chassis—many competitors pull 400–600W. Lower power means less cooling overhead in your data center or network closet and reduced operational cost over a five-year lifecycle.
- Operating temperature range -5 to +40°C: Suitable for standard climate-controlled data centers and network closets. Below 0°C or above 40°C, thermal throttling may engage; plan accordingly for outdoor enclosures or uncontrolled environments.
- NDAA Section 889 compliant, CE/FCC/IC/Anatel certified: Federal procurement and regulated sector deployments clear this hurdle out of the box. No supply chain documentation delays.
- UniFi Network management integration: Centralized provisioning, real-time monitoring, and troubleshooting via the UniFi controller—no separate management appliance, no license fees for core switching features. Auto-discovery and configuration workflows reduce deployment time.
- Layer 2 and Layer 3 interoperability: VLAN tagging, spanning tree, and link aggregation protocols ensure the USW-PRO-XG-AGGREGATION integrates transparently with third-party access switches, firewalls, and routers. SFP28 ports accept optics from multiple vendors.
- Compact 1U form factor, 7.1 kg weight: 442.4 × 43.7 × 480 mm (17.4 × 1.7 × 18.9 inches) fits standard server racks. Mounting bracket included; no custom rack adaptation required.
Deployment Contexts
Deploy the USW-PRO-XG-AGGREGATION as a core aggregation point in campus networks with multiple building distribution frames, as a data center east-west backbone consolidating traffic from compute and storage, or as a high-capacity interconnect between geographically separated network closets. Organizations moving access layers to 10G or 25G should evaluate this switch early in topology planning—it absorbs capacity growth without becoming a constraint. Redundant fiber runs between spine and leaf layers or across buildings benefit significantly from the non-blocking architecture.
Integration and Compatibility
The USW-PRO-XG-AGGREGATION integrates natively with Ubiquiti UniFi switches and routing appliances and operates as a standards-compliant Layer 2/3 device with third-party infrastructure. Full feature richness—analytics dashboards, unified VLAN management, and detailed traffic insights—emerge when paired with UniFi ecosystem components. If your access layer mixes vendors, SFP28 fiber connections and VLAN tagging ensure transparent integration; management tools may be simpler if the entire stack is Ubiquiti. Consult network switch selection guidance to align aggregation capacity with your access layer architecture.
Installation and Commissioning
Unbox the USW-PRO-XG-AGGREGATION, secure it to your rack using the included SGCC steel mounting bracket, and connect Ethernet management to your network. The UniFi Network application auto-discovers the switch on the local segment and guides initial setup via a web interface. Assign management VLAN, configure uplinks, and deploy via the controller in under 10 minutes. Ensure adequate ventilation around intake and exhaust; the switch draws up to 200W at peak load, but thermal design keeps fan noise moderate. No console cable required for standard deployments.
Frequently Asked Questions
Q: Does the USW-PRO-XG-AGGREGATION support LACP (Link Aggregation Control Protocol)?
A: Yes. Standard 802.3ad link aggregation is supported, allowing you to bond multiple SFP28 ports for redundancy or increased capacity to downstream switches or servers.
Q: What is the maximum distance for SFP28 fiber connections?
A: Distance depends on the optic—typical single-mode SFP28 LR4 transceivers support 10 km. Confirm your optic's specifications. The switch accepts third-party modules.
Q: Is the USW-PRO-XG-AGGREGATION NDAA Section 889 compliant?
A: Yes, it carries NDAA compliance, making it eligible for federal procurement and regulated sector deployments without additional certification delay.
Q: Can I mix 25G and 10G ports on the same switch for downlink aggregation?
A: Yes. Each SFP28 port auto-negotiates to 25G, 10G, or 1G—install 10G optics in ports connected to 10G access switches and 25G optics in ports serving 25G uplinks or servers. No configuration required.
Q: What cooling and power redundancy options are available?
A: The switch includes a single 200W power supply. For redundancy, confirm your data center or cabinet layout supports dual AC feeds or UPS circuits. Cooling is passive-assisted; ensure intake and exhaust paths are unobstructed.
Q: Does the USW-PRO-XG-AGGREGATION require external controllers or licenses?
A: No. Core switching, VLAN management, and link aggregation operate without license fees. UniFi Network controller (cloud or on-premises) provides unified management and monitoring dashboards. Controller is optional for basic switching; recommended for multi-site deployments.

The Ubiquiti USW-PRO-XG-AGGREGATION addresses a real gap in mid-market and enterprise switching architectures. Its 1.2 Bpps forwarding rate and 800 Gbps non-blocking throughput make it a credible aggregation point, and the 32-port 25G SFP28 layout maximizes fiber density without forcing optic license dependencies or vendor lock-in. NDAA compliance is a significant advantage for federal and regulated sectors—you clear that hurdle at purchase, not six months into procurement.
Technical Highlights:
- 1.6 Tbps switching fabric with 800 Gbps non-blocking throughput: Real benefit is predictable performance under load. Aggregate eight 10G access switches, and each sees full 10G to the core without the fabric becoming a chokepoint. Campus fiber runs and server-to-server traffic won't queue inside the switch.
- 32 x 25G SFP28 ports auto-negotiating to 10G or 1G: Eliminates speed mismatch penalties and allows heterogeneous downlinks in the same chassis. Mix vendors' 10G and 25G optics—the switch doesn't care as long as module types match (SR, LR, etc.).
- 200W maximum power draw: Competitive advantage over competing 32-port 25G aggregation switches pulling 400–600W. Meaningful savings in cooling overhead and operational cost, especially in power-constrained data center cabinets.
- 1,000 VLAN support, Layer 2/3 interoperability: Standard spanning tree and link aggregation protocols ensure transparent integration with third-party access layers and edge firewalls. Not a walled garden.
Deployment Considerations:
- SFP28 optics are not included—cost optics (typically $100–300 per module) into your BOM. Budget for diverse transceiver types if mixing speed tiers.
- Single 200W power supply; no built-in redundancy. Pair with cabinet-level UPS or dual AC feeds for high-availability topologies. Controller is optional for basic operation but recommended for multi-site management and monitoring.
- Thermal design is passive-assisted fan cooling; ensure rack ventilation is adequate. In cramped or warm environments (>35°C ambient), monitor inlet temps during peak traffic.
The USW-PRO-XG-AGGREGATION is the right choice for organizations moving access layers to 10G+ and needing a cost-effective, non-blocking spine for campus or data center cores. If you're still running 1G or Gigabit aggregation, this is over-provisioned; if you're running dual-10G uplinks with no growth path, this chassis absorbs capacity for 3–5 years.
