The Cisco Catalyst 4948E and 4948E-F Ethernet Switches are the Cisco Catalyst 4900 Series data center switches built from the start to deliver best-in-class, full-featured server-access switching. The switches include identical features except that the Cisco Catalyst 4948E offers front-to-back cooling, and the Cisco Catalyst 4948E-F offers back-to-front cooling. Each switch offers forty-eight 10/100/1000-Gbps RJ45 downlink ports and four 1 and 10 Gigabit Ethernet uplink ports. The switches are designed to simplify data center architecture and operations by offering service provider-grade hardware and software in a one-rack-unit (1RU) form factor optimized for full-featured top-of-rack (ToR) data center deployments.
