Cisco Catalyst 4948 10 Gigabit Ethernet Switch
10 Gigabit Ethernet Switching for High-Performance, Rack-Optimized Server Switching
Product Overview
The Cisco Catalyst
fixed-configuration switch for rack-optimized server switching. Based on the proven Cisco
hardware and software architecture, the Cisco Catalyst 4948 10 Gigabit Ethernet Switch offers exceptional
performance, bandwidth, and reliability for low-density, multilayer aggregation of high-performance servers and
workstations. High performance and scalability of intelligent network services is made possible with dedicated
specialized resources known as ternary content addressable memory (TCAM). Ample TCAM resources (64,000
entries) enable high feature capacity, providing wire-speed routing and switching performance with concurrent
provisioning of services such as quality of service (QoS) and security and helping ensure scalability for today's
network requirements with ample room for future growth.
The Cisco Catalyst 4948 10 Gigabit Ethernet Switch 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).
