The Ubiquiti USW-Pro-Max-16 is a managed switch designed to operate under the UniFi system. It features 12 gigabit Ethernet ports (10/100/1000 Mbps), 4 2.5G Ethernet ports (1000/2500 Mbps), and 2 SFP+ slots (10 Gbps). It boasts a maximum switching capacity of 84 Gbps and a packet forwarding rate of 62 Mpps. Switches from the Pro Max series are known for their advanced management features. In addition to supporting Layer 2 functions such as IGMP Snooping, port isolation, Voice VLAN, and DHCP Snooping, they also provide basic Layer 3 functionalities. The device supports DHCP, DHCP relay, Inter-VLAN routing, static routing, and network isolation based on access control lists. The Pro Max 16 is suitable for any UniFi network that requires a high-performance switch with robust management capabilities.
Port Configuration & Performance
-
12x Gigabit RJ45 Ports: Standard 10/100/1000 Mbps ports for connecting most clients like computers, printers, IoT devices, and access points.
-
4x 2.5G Multi-Gig RJ45 Ports: These are a major highlight. They auto-negotiate to 100M/1G/2.5G, making them perfect for:
-
2x SFP+ Fiber Ports: 10 Gigabit ports for high-bandwidth uplinks. You can use them to:
-
Connect to another switch or a core router (10G uplink).
-
Connect to a server with a 10G network interface card (NIC).
-
Use with SFP+ to RJ45 transceivers for 10G copper connections.
-
Performance: The 84 Gb/s switching capacity and 42 Gb/s non-blocking throughput confirm that all ports can run at full duplex, wire-speed simultaneously without any congestion.
Hardware & Design
-
Enclosure: Made of SGCC steel, making it far more durable and robust for rack mounting than switches with plastic enclosures. It also helps with heat dissipation.
-
LCM Touchscreen: The 1.3" touchscreen is a unique feature that provides at-a-glance information like switch name, IP address, uptime, and network activity. It can be used for quick configuration changes and port status checks without opening the UniFi controller.
-
Power Efficiency: A remarkably low max power consumption of 25W for a switch of this capability, thanks to its efficient design and external power adapter.
Software & Management
-
Managed by UniFi Network Application: This switch is not standalone. It requires a UniFi controller (software running on a PC, cloud key, or self-hosted) for setup and management. The specified version is 8.1.127 or later.
-
Layer 2 Features: It includes a comprehensive suite of enterprise-grade switching features:
-
STP/RSTP: Prevents network loops.
-
LACP: Allows link aggregation to combine multiple ports for higher bandwidth and redundancy.
-
IGMP Snooping: Optimizes multicast traffic (e.g., for video streaming).
-
ACLs (Access Control Lists): For detailed security policies and device isolation.
-
DHCP Snooping/Guarding: Protects against rogue DHCP servers.
-
802.1X: Provides port-based network access control (enterprise authentication).
-
Layer 3 Features: This is what makes it a "Pro" model. It can perform inter-VLAN routing and static routing directly on the switch. This offloads traffic from your main router/gateway, improving overall network performance and efficiency for local traffic between VLANs (e.g., between a "Guest" network and a "Servers" network).
