LINKSYS A Division of Cisco Systems Inc cost effective secure switching with simplified management for your growing business Growing businesses require cost effective networking solutions that can scale with ever changing business needs The Linksys SLM248G4S Smart Switch with Resilient Clustering technology brings a whole new level of intelligence and security to the network infrastructure at a cost effective price It offers 48 10 100 Ethernet copper ports with four 10 100 1000 Gigabit Ethernet copper or optional optical SFP interfaces for uplinking the switch to the core network Network security is a top priority in any size business unauthorized access to the network and mission critical data is a constant concern The SLM248G4S is able to secure the network through 802 1X port authentication and MAC Filtering 802 1X requires clients to authenticate themselves before they are given access to the network The SLM248GAS switches provide Resilient Clustering technology which enables several switches to be clustered together and managed as a single switch with one Web Management interface and one IP address This technology allows up to 4 units of the SLM248G4S or up to 192 ports when combined with SLM224G4S to be set up in a switch cluster SLM248G4S units can coexist in a switch cluster with other Linksys Smart Switches that support Resilient Clustering technology SLM224G4PS SLM224G4S and SLM248G4PS Busines
