The Cisco Small Business SF500-48P is a 48-port Fast Ethernet stackable managed switch with Power over Ethernet Plus (PoE+) designed to provide a secure and reliable network foundation for growing businesses. It offers forty-eight 10/100 Mbps ports, all of which support PoE+, with a robust power budget of 375W. This allows you to power a large number of high-power devices such as IP phones, wireless access points, and video surveillance cameras directly from the switch. For high-speed connectivity, it also includes four Gigabit SFP ports for fiber uplinks to other switches or a server. The SF500-48P supports true stacking, enabling you to manage and configure up to eight physical switches as a single, unified device, which simplifies administration and ensures high availability. It includes advanced Layer 3 switching features, such as static and dynamic routing, for efficient network segmentation and traffic management. Security is a top priority, with features like Access Control Lists (ACLs), 802.1X port security, and IP Source Guard to protect your network. The switch is easy to manage through a web-based interface or a command-line interface (CLI) and supports Quality of Service (QoS) to prioritize critical network traffic, ensuring smooth performance for all applications.
