ZyXEL GS1920-24HP, 28-Port GbE L2 PoE+ Smart Switch

Todays small and medium sized businesses expect a higher level of performance from their networks, more connections to support diverse applications, fewer network disruptions and easier management. The ZyXEL GS1920 Series is ideal for small and medium sized deployments in multiple scenarios by providing up to 28 Gigabit Copper ports for 24 port models or up to 6 gigabit fibre ports for 48 port models.

With rich L2 features such as LACP, advanced QoS, VLAN, ACL and multicast IGMP snooping, the GS1920 Series offers intuitive web based interface for users to access without learning complex command-Line interface (CLI).

The GS1920 Series PoE Switches support 802.3at PoE Plus standards to offer 30 watt per port and a 375 watt high power budget to meet the connectivity needs of additional powered devices like 802.11 ac WLAN access points, VoIP Phones and IP Cameras. As well as featuring full PoE ports, the GS1920 Series employs intelligent technology. Whilst set to consumption mode, switches can automatically detect the power consumption status of each powered device and supply the amount of power required, saving businesses money.

The GS1920 Series protects users from network disruptions and ensures uniterrupted connectivity through several key features. Loop Guard helps networks avoid service disruptions caused by switching loops and IP Source Guard (IPSG) shields your network from MAC spoof and ARP spoof attacks.
