Zyxel GS1900-48HPv2 Managed L2 Gigabit Ethernet (10/100/1000) Power over Ethernet (PoE) Black

Near silent operationThe GS1900 Series includes both fan-less and built-in smart fan models. The smart fan is designed to automatically adjust speed based on device temperature. You can barely hear the sound while the switch is operating. It is ideal for your office environment.Intelligent PoE+ powers more devicesPoE models (8HP/10HP/24EP/24HPv2/48HPv2) come with default PoE consumption mode which delivers only the actual power required by your networked devices, reserves the rest and optimizes its power budget. That means a single switch can power more APs, IP cameras and VoIP phones, ensuring a better ROI for your business. All of them support the IEEE 802.3at providing a maximum of 30W per port.Speedy Gigabit performance built for SMBsThe GS1900 is a series of switches with full non-blocking bandwidth of up to 1 Gbps per port. An ideal upgrade from an unmanaged switch, it s a great choice for SMBs that want to enjoy high-speed business network applications at full wired non-blocking speed.Easy and intuitive managementThe Smart Managed GS1900 Series switch feature with web-based interface to manage advanced functions such as VLAN, QoS, IGMP Snooping, Link Aggregation (LAG), IPv6 and DoS prevention easily. Also, the user-friendly wizard helps to walk through setup, configuration and even advanced settings quickly.
