Four dedicated Gigabit SFP uplink ports allow you to have flexible fiber or copper backhaul to your core network and this 48-port Gigabit smart switch offers non-blocking 1 GbE connectivity for PCs, IP phones, printers, access points and servers. With its Layer 2+ and basic Layer 3 features, easy-to-use web-based management and strong security, the Cisco Business CBS250-48T-4G provides a strong basis for contemporary wired networks that must grow without becoming more complicated. With features like VLANs, QoS, link aggregation and advanced monitoring, this smart switch—which is made for high-speed desktop connectivity—allows you to divide traffic, give audio and video priority and promptly identify problems. It is perfect for offices, branch locations and SMB server rooms that require long-term dependability because of its energy-efficient technology, small rack-mount architecture and limited lifetime guarantee. Whether you are expanding an existing Cisco Business deployment or upgrading from unmanaged switches, this Cisco 48-port Gigabit switch with SFP uplinks provides the performance, visibility and management you need to maintain user productivity.
