Overview
The Cisco Catalyst
deliver high performance, integrated Layer 2, 3 and 4 switching with intelligent
services, for network control and resiliency. These switches offer a rich variety of
1000-Mbps Gigabit Ethernet modules that include both fiber, and copper, interfaces
for Gigabit server and desktop Enterprise switching solutions and Service Provider
metropolitan Ethernet networks. Gigabit Ethernet switching modules include
cost-effective, high-performance 1000BASE-X Gigabit Interface Converter
(GBIC)-based Gigabit Ethernet line cards and the highest density 48-port 10/100/
1000BASE-T triple speed auto-sensing, auto-negotiating Gigabit Ethernet line card
and system in the industry.

Card (WS-X4448-GB-RJ45)
The Cisco Catalyst 4000/4500 Series
48-port 10/100/1000BASE-T line card
extends Cisco's leadership in the modular
switched Ethernet market, providing the
industry's highest density auto-negotiating
Gigabit Ethernet from the network edge
directly to desktop computers. This line
card provides 48 RJ-45 ports with triple
speed auto-sensing and auto-negotiating
technology, enabling all ports to be used at
10 Mbps, 100 Mbps, or 1000 Mbps up to
100 meters over Category 5 copper
cabling for optimum flexibility and
investment protection. This module
provides wiring closet investment
protection by allowing Fast Ethernet
desktops today to migrate to Gigabit
Ethernet in the future without replacing
