Growing businesses require cost-effective, networking solutions that can scale with ever-changing business needs. The Linksys SLM224G4PS Smart Switch 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 to core network or servers. Network security is a top priority in any size business and unauthorized access to the network and mission critical data is a constant concern. The SLM224G4PS is able to secure the network through 802.1X port authentication and MAC Filtering. 802.1X requires clients to authenticate themselves before the port will pass data and allow a user to access the network. For Wireless or VoIP deployments, the SLM224G4PS supports the IEEE802.3af standard for Power over Ethernet (PoE). This eliminates the need for additional power cables or for a power outlet to be nearby. It enables POE-enabled devices such as IP cameras, IP phones, and Wireless Access Points to be positioned in optimal locations like in ceilings and walls--even outdoors--and in locations where there is a an accessible power outlet, thereby reducing installation costs making installations easier.
