Switching Performance
The UniFi Switch offers the forwarding capacity to simultaneously process traffic on all ports at line rate without any packet loss.
PoE+ Flexibility
The UniFi Switch models are available with 8, 16, 24, or 48 PoE Gigabit Ethernet ports of auto-sensing IEEE 802.3af/at or configurable 24V passive PoE to simplify your infrastructure. By default, the UniFi Switch automatically detects 802.3af/at devices so they automatically receive PoE. For 24V passive PoE devices, manually enable 24V passive PoE using the UniFi Controller software.
Fiber Connectivity
The UniFi Switch provides fiber connectivity options for easy expansion of your networks. Each UniFi Switch model includes two SFP ports for uplinks of up to 1 Gbps. Each 48-port model adds two SFP+ ports for high-capacity uplinks of up to 10 Gbps, so you can directly connect to a high-performance storage server or deploy a long-distance uplink to another switch.
Features:
Powerful Enterprise Switch Models
The UniFi Switch delivers the forwarding capacity to simultaneously process traffic on all ports at line rate without any packet loss. Total non-blocking throughput: up to 26 Gbps for 24-port models and up to 70 Gbps for 48-port models.
Advanced Port Management
Each switch port offers custom settings: port name, PoE, network/VLAN configuration, and operation mode (switching, mirroring, or aggregate).
Optical Fiber Connectivity
Two SFP ports support uplinks of up to 1 Gbps. For high-capacity uplinks, each 48-port model includes two SFP+ ports for uplinks of up to 10 Gbps.
Convenient PoE+ Support
The UniFi Switch features auto-sensing IEEE 802.3af/at and 24V passive PoE to power multiple devices on the network.
Seamless Integration
The UniFi Switch integrates seamlessly into the UniFi Software-Defined Networking (SDN) platform to create a highly scalable, end-to-end system of network devices across multiple locations — all controlled from a single interface.

Software:
Advanced Network Switching
Managed by the UniFi Controller software, the UniFi Switch delivers powerful performance, intelligent switching, and PoE+ support for your enterprise networks.
UniFi Controller
Designed for convenient management, the UniFi Controller software allows admins to configure and monitor the UniFi Switch and other UniFi devices using a graphical user interface. You can download it from www.ubnt.com at no extra charge – there is no separate software, licensing, or support fee.
Multi-Site Management
A single instance of the UniFi Controller running in the cloud can manage multiple UniFi sites within a centralized interface. Each site is logically separated and has its own network monitoring, configuration, maps, statistics, and admin accounts.
Switch Configuration
You can access any managed UniFi Switch through the UniFi Controller to configure a variety of features:
- PoE setting per port
- Operation mode (switching, mirroring, or aggregate) per port
- Network/VLAN configuration
- Jumbo frame and flow control services
- Network settings
- Storm control setting per port
- Spanning tree configuration
Switch Port Status
You can also view status information for each port:
- Connection speed and duplex mode
- TX/RX data rates
- PoE status
- Network/VLAN setting
Dashboard
The Dashboard tab provides a visual representation of your network's status. Basic information is provided for each network segment.
Device Configuration
The Devices screen displays the UniFi devices discovered by the UniFi Controller. You can access each managed device for device details and configuration.

The standard TOUGHCable Connectors are available in a box of 100, while the TC-GND versions include ground wires and are available in a box of 20.
| ESD attacks are the leading cause for device failures. The diagram below illustrates the areas vulnerable to ESD attacks in a network. |
By using a grounded Ubiquiti Power over Ethernet (PoE) Adapter along with Ubiquiti TOUGHCable and TOUGHCable Connectors, you can effectively protect against ESD attacks. |
