ZyXEL GbE Smart Managed PoE Switch 48-port GS1920-48HP
Attach a variety of devices including access points, IP cameras, and more to the GS1920-48HP 48-Port GbE Smart Managed PoE Switch from ZyXEL. With 44 PoE Gigabit Ethernet ports, 2 Gigabit SFP ports, and four Gigabit SFP/RJ-45 combo ports this switch is capable of powering a number of PoE compatible devices eliminating the need to run separate power sources to each connected device. The four SFP ports are designed to support a variety of connection options including SONET, gigabit Ethernet, Fibre Channel, and more.
The GS1920-48HP features a 375 Watt total PoE power budget giving you enough power to allocate among a variety of connected devices. The 100 Gbps switching capacity ensures the switch can handle a large amount of data quickly and efficiently while the 16 K MAC address table allows you to store a large number of MAC addresses.
To increase power efficiency the GS1920-48HP is capable of detecting the amount of power required by each connected device ensuring excess power is not provided to the port the device is connected to. In addition to power efficiency, the GS1920-48HP comes equipped with features to prevent against network disruptions including Loop Guard, IP Source Guard, and dual firmware imaging.
Advanced Standard Compliance with Intelligent Power Function Support
The ZyXEL GS1920-48HP PoE switch supports the 802.3at PoE Plus standard, with a 375-watt high-power budget to meet the connectivity needs of additional powered devices like 802.11ac WLAN access points, VoIP phones and IP cameras. Not only does the GS1920-48HP PoE switch feature full PoE ports, it also employs intelligent technology. While set to Consumption Mode, this switch can automatically detect the power consumption status of each powered device and supply only the amount of power required. This intelligent power allocation function minimizes wasteful overpowering of devices, thereby helping businesses save money, while enabling the PoE switch to power more devices.

Robust Network Availability
Network disruptions are a frequent source of headaches for small to medium-sized businesses. Whether outages are caused by internal errors or outside attack, this ZyXEL GS1920-48HP switch protects users from network disruptions and ensures uninterrupted 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. Additionally, attacks such as BPDU, ARP and IGMP can target network facilities. However, CPU protection guarantees that a network continues to operate, even while under attack. Furthermore, dual firmware image and configuration features improve network reliability and availability.
Access Protection to Secure the Network
The ZyXEL GS1920-48HP switch provides efficient allocation of network resources while ensuring comprehensive access protection, along with simple and secure network control. Not only does the GS1920-48HP switch support 802.1X authentication with RADIUS, it can monitor, filter and police all traffic between clients within the same subnet, creating an even higher degree of security.
