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).
