Zyxel GS1920-48V2 Managed Gigabit Ethernet (10/100/1000) Black

The Zyxel GS1920-48V2 is a managed Gigabit Ethernet switch designed for small and medium businesses that need reliable, future-ready networking. It provides 44 Gigabit RJ-45 ports, a switching capacity of 100 Gbit/s and a MAC address table of 16,000 entries. The switch supports common L2 standards (including IEEE 802.1Q, 802.1x and LACP) and offers up to 375 W PoE budget to power connected devices. Rack-mountable and finished in black, the GS1920-48V2 includes an intuitive web interface and integration with Zyxel One Network (ZON) for simplified configuration and remote management.

Advantages

The GS1920-48V2 delivers managed L2 features without requiring command-line expertise, using a web-based UI for VLAN, ACL, advanced QoS, LACP and IGMP snooping. A 375 W PoE budget and a consumption mode let the switch allocate only the power needed to connected devices, improving efficiency and device density. The unit also supports Zyxel Smart Connect for remote factory reset and power cycling, and a temperature-controlled Smart Fan for quiet operation in office or rack environments.

Suitable for

• Small and medium business networks
• Office floor switching and rack installations
• Powering PoE devices such as IP phones, access points and cameras
• Environments requiring VLANs, QoS and access control

How to use

Install the GS1920-48V2 in a standard 19-inch rack or place it on a desktop and connect power. Use the web-based management interface or the free Zyxel One Network (ZON) utility to discover the switch, configure VLANs, QoS, LACP and security policies, and monitor port status. If using PoE devices, connect them to the RJ-45 ports; enable consumption mode if you want the switch to allocate power only as required. Firmware updates and Smart Fan controls are available via the management interface.

Recommendations

For stable operation, place the switch in a ventilated area and keep firmware up to date. Use Zyxel One Network (ZON) to simplify large-scale deployments and enable Smart Connect features for remote power cycling and device recovery.
