Description
UniFi Managed 48-port L2 Gigabit PoE+ Switch with Hot Swap PSUs
Build and expand your network with the UniFi® Switch, part of the Ubiquiti Networks® UniFi Enterprise System. The UniFi Switch, model US-L2-48-POE, is a configurable Gigabit Layer-2 switch with auto-sensing 802.3at PoE+. It offers 48 RJ45 Ethernet ports, two SFP, and two SFP+ ports that provide Gigabit PoE links to your devices and up to 10G fiber uplink options to your enterprise network.
The US-L2-48-POE features an efficient front/back airflow design and modular PSUs with integrated fans for quiet cooling. It utilizes up to two hot-swappable PSU bays and includes one 250W AC/DC PSU. Customize your switch configuration with an optional AC/DC or DC/DC power supply for additional power, redundancy, and load balancing. With the US-L2-48-POE, you have the flexibility to power more devices on your network now and in the future.
UniFi Controller
Managed and configured by the UniFi Controller with UniFi Mobile app support, the UniFi Switch offers an extensive suite of advanced Layer-2 switching protocols and features, including operation mode (switching, mirroring, or aggregate) per port. The UniFi Controller and mobile app allows admins to configure and monitor virtually all of the switch features in a graphical user interface from anywhere.
