Zyxel GS1920-48V2-EU0101F - Smart Managed Gigabit Ethernet Switch, Black

The Zyxel GS1920-48V2-EU0101F is a Smart Managed Gigabit Ethernet switch designed for network segmentation and traffic control in medium to large offices. It features 44 Gigabit RJ-45 ports, four combo Gigabit ports, and two dedicated SFP slots for fiber uplinks. This non-PoE model supports a 100 Gbit/s switching capacity to handle heavy local area network traffic. With a forwarding rate of 74.4 Mpps, the switch prevents congestion during periods of high demand. Administrators can use the 48 copper interfaces to aggregate connections for desktop PCs, printers, and other non-PoE hardware.

The 1U chassis fits standard 19-inch racks and measures 440 x 220 x 44.5 mm. Engineers can configure settings via a local web GUI, command-line interface, or a cloud management platform. The switch provides traffic management through Quality of Service algorithms, including SPQ, WFQ, and Weighted Round Robin. Security is handled via Access Control Lists, ARP inspection, and 802.1X RADIUS authentication to isolate unauthorized devices. The unit consumes a typical 36.9 W and produces 26 dB of acoustic noise, allowing it to operate quietly in server rooms or wiring closets.
