WS-X4248-RJ45V Overview<\/p>\n
The Cisco WS-X4248-RJ45V is a 48-port Fast Ethernet line card for the Catalyst 4500 Series, built to provide high-density access connectivity with full IEEE 802.3af Power over Ethernet support. Each port delivers 10\/100 Mbps Fast Ethernet through standard RJ-45 copper interfaces, making the module well-suited for connecting end devices such as desktops, printers, Cisco IP phones, and wireless access points. With PoE support, it can directly power network devices over the Ethernet link, reducing the need for separate electrical cabling and simplifying deployment of voice and wireless infrastructure. Designed for enterprise campus networks, the WS-X4248-RJ45V integrates seamlessly with Catalyst 4500 Supervisor Engines to leverage centralized control.<\/p>\n","protected":false},"featured_media":25081,"comment_status":"closed","ping_status":"open","template":"","meta":{"_acf_changed":false},"product_brand":[255],"product_cat":[2915,332],"product_tag":[2948,363,337],"class_list":["post-25080","product","type-product","status-publish","has-post-thumbnail","product_brand-cisco","product_cat-cisco-network-switches-network-switches","product_cat-network-switches","product_tag-48-ports","product_tag-cisco","product_tag-fast-ethernet","first","instock","shipping-taxable","product-type-simple"],"acf":[],"yoast_head":"\n
