FEATURES- 24-Port 10/100/1000 Gigabit Switch
       Ethernet switch with 24-port 10/100/1000 with 4 shared SFP slots 
        with stacking!
       SGE2000 is optimized for maximizing the system availability with 
        fully redundant Stacking, Redundant Power options, and Dual Images 
        for resilient firmware upgrades. The SGE2000 is able to secure the 
        network through IEEE 802.1Q VLANs, IEEE 802.1X port authentication, 
        Access Control Lists (ACL), DOS Prevention, and MAC-based 
        filtering. The enhanced QoS and traffic management features ensure 
        clear and reliable voice and video communications.
       The SGE2000 switches provide an intuitive, secure management 
        interface enabling you to better utilize the comprehensive feature-
        set of the SGE2000, resulting in a better optimized, more secure 
        network. 
       Software running on the SGE2000 Ethernet Switch interacts with 
        provisioning, management, and security software on the site's 
        services router and interacts further upstream to the service 
        provider. This interaction provides a simple, one-step installation 
        and access to webadministered features for the administrator and 
        users. Simple, affordable network operations throughout the 
        network's lifetime are the result. 
       Linksys Business Series SFE and SGE Stackable Switch products are 
        Linksys One Ready. That means they include the necessary firmware 
        to be seamlessly integrated into a Linksys One data or data/voice 
        network. Once connected, a Linksys One Service Router will discover 
        the SFE/SGE device, automatically configure it and make it 
        available to other users on the network. Linksys One technology is 
        automatic and self-configuring. When Linksys One peripherals are 
        connected to a Linksys One Ready Ethernet Switch's ports, small 
        businesses are ready to communicate in a matter of minutes. 
    Includes SGE2000 Ethernet Switch, Console cable, AC power cord, 
      Rackmount kit, Quick installation guide.
