10 Gigabit Ethernet Switching for High-Performance, Rack-Optimized Server Switching
The Cisco® Catalyst® 4948-10GE Switch is a wire-speed, low-latency, Layer 2-4, 1-rack-unit (1-RU), fixed-configuration switch for rack-optimized server switching. Based on the proven Cisco Catalyst 4500 Series hardware and software architecture, the Cisco Catalyst 4948-10GE offers exceptional performance, bandwidth, and reliability for low-density, multilayer aggregation of high-performance servers and workstations.
The Cisco Catalyst 4948-10GE offers 48 ports of wire-speed 10/100/1000BASE-T with 2 ports of wire-speed 10 Gigabit Ethernet (X2 optics). Exceptional reliability and serviceability are delivered with optional internal AC or DC 1+1 hot-swappable power supplies and a hot-swappable fan tray with redundant fans (Figures 1 and 2).
