WS-X4448-GB-RJ45 Overview<\/p>\n
The Cisco WS-X4448-GB-RJ45 is a high-density Gigabit Ethernet line card for the Catalyst 4000 Series chassis, offering 48 auto-sensing 10\/100\/1000 Mbps RJ-45 ports. Designed to deliver wire-speed performance with flexible connectivity, it provides enterprises with a scalable and cost-effective way to migrate from Fast Ethernet to Gigabit Ethernet at the access or distribution layers. Each port supports copper connections over standard twisted-pair cabling, making it easy to deploy in wiring closets without requiring fiber infrastructure. The module integrates seamlessly with Catalyst 4000 Supervisor Engines, enabling centralized switching performance, robust security, VLAN segmentation, and advanced Quality of Service features to prioritize latency-sensitive traffic such as voice and video.<\/p>\n","protected":false},"featured_media":25039,"comment_status":"closed","ping_status":"open","template":"","meta":{"_acf_changed":false},"product_brand":[255],"product_cat":[2915,332],"product_tag":[2945,2948,363,3517],"class_list":["post-25038","product","type-product","status-publish","has-post-thumbnail","product_brand-cisco","product_cat-cisco-network-switches-network-switches","product_cat-network-switches","product_tag-rj-45","product_tag-48-ports","product_tag-cisco","product_tag-mstp","first","instock","shipping-taxable","product-type-simple"],"acf":[],"yoast_head":"\n
