Zyxel GS2220-50HP - Managed Layer 2 Gigabit Ethernet Power over Ethernet Plus Switch, Black

The Zyxel GS2220-50HP-EU0101F 48-Port L2 Managed Gigabit PoE+ switch segments local area networks and provides centralized control over connected endpoint devices. This model features 44 Gigabit RJ-45 ports and four combo SFP slots for flexible uplink connections. Operating at Layer 2, the switch provides a total switching capacity of 100 Gbit/s and a forwarding rate of 74 Mpps to maintain data flow across high-density networks. Built-in Power over Ethernet capabilities allow the switch to power IP cameras, wireless access points, and VoIP phones directly.

The chassis is designed for standard rack mounting and operates at a noise level of 49.5 dB. It provides a total PoE budget of 375 W, with a maximum power consumption of 474.3 W at full load. Administrators can configure the unit via a web-based graphical interface or a command-line interface. Traffic management options include port-based, private, protocol-based, and voice VLAN configurations to isolate data streams. Network security relies on IEEE 802.1x and RADIUS authentication, backed by access control lists to restrict unauthorized access.
