Ubiquiti USW-PRO-MAX-48 48-Port Managed Network Switch
The Ubiquiti USW-PRO-MAX-48 (often searched as USW PRO MAX 48) is a 1U rack-mounted managed switch purpose-built for enterprise and mid-market network deployments where heterogeneous port speeds and deterministic switching performance matter. With 224 Gbps switching fabric and 112 Gbps non-blocking throughput, this switch handles full-duplex operation across all ports simultaneously—meaning no bandwidth bottlenecks even when all connections are saturated. For integrators deploying campus access switches, multi-building enterprise LANs, or three-tier switching hierarchies, the port configuration delivers practical flexibility without forcing you to overpay for unused uplink capacity.
Key Features
- Port Configuration (32×1G + 16×2.5G + 4×10G SFP+): The heterogeneous approach reduces capex compared to all-10G designs while preserving fast uplinks. The 32 Gigabit Ethernet ports serve edge access (IP cameras, access points, workstations), the 16 ports at 2.5 Gbps absorb traffic from servers or dense closets without full 10G cost, and four SFP+ ports connect to core infrastructure or redundant paths. You pay only for the speed you need at each tier.
- 224 Gbps Switching Capacity, 167 Mpps Forwarding Rate: This throughput handles bursty multi-camera streams and simultaneous file transfers without queuing delays. In surveillance or automated warehouse deployments, deterministic latency keeps video and control traffic flowing on schedule.
- 1,000 VLAN Support: Isolate tenants, departments, or security zones without external appliances. VLAN-per-camera or VLAN-per-zone architectures become straightforward to implement and audit.
- 100W Power Consumption: Draws only 100W under typical load from a universal AC/DC supply (100–240V, 50/60 Hz). Low power means less cooling load in dense racks and fewer circuit breaker trips in branch offices or metered environments. Multiple switches fit comfortably on a single 20A branch circuit.
- UniFi Controller Integration: VLAN management, port profiles, and traffic policies configure centrally through the UniFi dashboard. No CLI required for routine administration; SNMP and standard Ethernet management ports simplify integration into existing network stacks.
- Compact 1U Footprint (442 × 325 × 44 mm, 4.8 kg): Fits standard 19-inch racks without modification. At 4.8 kg (10.6 lb), installation and repositioning during maintenance is practical. Passive cooling or standard rack airflow suffices; operating temperature range of –5 to 40°C permits deployment in lightly cooled or outdoor-adjacent infrastructure spaces.
- NDAA-Compliant (CE, FCC, IC, Anatel: 06373-24-08356): Meets U.S. defense and international regulatory requirements, critical for government, healthcare, and regulated enterprise procurement.
Integration and Deployment Context
The USW-PRO-MAX-48 integrates seamlessly into managed network switch architectures. Fiber uplinks via the 4×10G SFP+ ports connect to core switches, routers, or redundant data paths. In a three-tier campus network, one USW-PRO-MAX-48 per building or zone provides 48 local access ports while the small uplink footprint keeps cabling tidy. In warehouse automation environments, high-speed SFP+ ports aggregate traffic from multiple access layers (barcode scanners, industrial Ethernet devices, mobile computers) feeding into edge computing or cloud systems. SGCC steel enclosure ensures durability across standard data center and industrial conditions.
Refer to network infrastructure buying guides for campus architecture patterns and uplink capacity planning. For PoE camera deployments requiring higher power density, pair this switch with dedicated PoE power supplies or PoE injectors on the Gigabit ports.
Frequently Asked Questions
Q: Does the USW-PRO-MAX-48 support static routing or just switching?
A: The USW-PRO-MAX-48 is a managed Layer 2 switch with VLAN routing via the UniFi controller. For complex multi-subnet networks, add a router upstream to the 10G SFP+ ports.
Q: What's the maximum current draw if I daisy-chain multiple switches on one circuit?
A: Each USW-PRO-MAX-48 draws 100W nominal. Three switches consume approximately 300W, fitting within a standard 20A 120V branch circuit (2400W). However, confirm actual load and consult your electrical drawings; metered outlets are preferable in production environments.
Q: Can I use multimode fiber in the 10G SFP+ ports?
A: Yes. The ports accept standard SFP+ modules (LC duplex). Match fiber type and distance to your module choice—SR (short range, ~300m multimode) or LR (long range, ~10km singlemode). No proprietary modules required.
Q: Does the switch support RADIUS authentication for management access?
A: Management is performed via the UniFi controller, which supports RADIUS and LDAP backend authentication. Individual switch CLI access is possible but typically unnecessary in UniFi deployments.
Q: What's the warranty period?
A: Refer to the Ubiquiti product warranty documentation or contact the specialty distributor. Standard Ubiquiti hardware carries a 1-year limited warranty; extended coverage is available separately.
Q: Is the USW-PRO-MAX-48 NDAA Section 889 compliant?
A: Ubiquiti products carry NDAA compliance certifications where applicable. Confirm compliance status with the distributor or Ubiquiti for your specific procurement requirement.

The USW-PRO-MAX-48 solves a recurring problem in mid-market campus deployments: you need 48 ports of local access switching, but you don't need (or can't afford) 48 ports of 10G. This port split—32×1G, 16×2.5G, 4×10G—hits the sweet spot. In a typical building, the 32 Gigabit ports serve IP cameras, access points, and workstations; the 16 2.5G ports handle a small number of servers or aggregation points without capex waste; and the four SFP+ ports carry backbone traffic to your core. That's practical network design.
Technical Highlights:
- 112 Gbps Non-Blocking Throughput: Every port pair can communicate at full wire rate simultaneously. In surveillance, this means all 48 cameras can stream 24/7 at line rate without queue buildup or dropped frames—measurable reliability for monitoring SLAs.
- 100W Power Budget: Three of these switches draw 300W total, leaving headroom on most branch PDUs. Compare to all-10G designs drawing 150–200W each—the USW-PRO-MAX-48 cost difference compounds over larger deployments.
- 1,000 VLAN Support + UniFi Controller Orchestration: One central dashboard configures VLAN memberships, port profiles, and QoS rules across the entire switch inventory. No CLI per switch. In hospital or warehouse environments where you need security zone isolation (cameras on VLAN-A, access control on VLAN-B), this simplicity is a competitive advantage.
Deployment Considerations:
- The 2.5G ports are bottlenecks only if you attach 10G servers directly; in campus access roles, they're ideal for POE+ aggregation (Cisco Catalyst 9000 APs, modern Hikvision NVRs with bonded links).
- SFP+ fiber modules are separate purchases; budget $30–150 per module depending on distance (SR multimode vs. LR singlemode). Lead time can stretch procurement if not ordered early.
- Management traffic flows in-band via Ethernet or the Gigabit uplink; if your UniFi controller is on a separate VLAN, verify controller reachability before switching goes live.
Deploy the USW-PRO-MAX-48 as your primary campus access switch in 2-to-5-building networks, or as a secondary aggregation layer in larger hierarchies. It's cost-effective, low-power, and integrates tightly with UniFi infrastructure—especially valuable if you're standardizing on Ubiquiti across IP cameras, access points, and firewalls.
