[. . . ] Key Features Advanced L2 switching features 56/100 Gbps non-blocking switch fabric (GS2200-24/24P: 56 Gbps, GS2200-48: 100 Gbps) 4 Dual-personality (RJ-45/SFP) GbE interfaces Port security and enhanced 802. 1x port authentication MAC freeze and intrusion lock 8 IEEE 802. 1p hardware priority queues WFQ, WRR and SPQ queuing algorithms IEEE 802. 3af Power over Ethernet (GS2200-24P only) PoE Power consumption mode for energy saving (GS2200-24P only) The ZyXEL Gigabit Switch 2200 Series consists of three switches: the ZyXEL GS2200-24, GS2200-24P and GS2200-48. [. . . ] ZyXEL iStackingTM clustering management technology can manage devices across different floors and routing domains to locate other iStacking-capable switches in the same management cluster. This allows administrators to manage 24 switches with one single IP address. This greatly reduces operating costs and offers more flexible maintenance of ZyXEL Switches. IT staff can opt for the Web or command line interface to suit their needs, and even encrypt their instructions with SSHv1/v2 and SSL. With these sophisticated functionalities, the IT staff is empowered to build a highly secure and efficient corporate network with minimum effort. Future proof networking with minimum disruption The ZyXEL 2200 Series provides rich features including VLANs, CoS/QoS, Port Trunking, Rapid Spanning Tree, Security (Port Security and 802. 1x authentication) and network management to meet evolving SME requirements. Meanwhile, it delivers the most cost-effective Gigabit Ethernet solution to empower Gigabit converged networking for branch offices and SME users. Intelligent PoE for cost saving (GS2200-24P only) ZyXEL's Intelligent PoE features provide two power supply modes: - Classification mode: the switch reserves the maximum power (W) to each powered device (PD) according to the priority levels. - Consumption mode: the switch manages the entire power supply, so each connected PD gets the actual power it needs. Enterprise LAN Switches Switch 2200 Series In the Consumption Mode, ZyXEL's Intelligent PoE will reserve the required power automatically, and you can set power feeding priorities on different ports to get the best use of power resource. This capability can increase the number of devices connected and deliver a better ROI for the business. [. . . ] All specifications are subject to change without notice. [. . . ]
