The industry-proven Cisco IOS Software network service strategy spans years of customer-suggested evolution to

meet the most demanding network needs. Networks benefit from the breadth and depth of these network services

and mature protocols.

Cisco Catalyst 4003 and 4006 switches offer a comprehensive, scalable suite of 10/100/1000-Mbps Ethernet switch

modules that deliver hot-swappable, “plug-and-play” enterprise intelligence today, while providing easy growth and

flexible protection to keep pace with the increasing network demands of tomorrow. Several Cisco Catalyst 4000

Series modules are available, which can be mixed and matched to suit numerous wiring-closet, data-center, or

branch-office deployments. All Gigabit Ethernet ports can be 1000BASE-SX, 1000BASE-LX/LH, or 1000BASE-ZX

by using flexible, hot-swappable gigabit interface converter (GBIC) modules. The Cisco Catalyst 4000 Series

supports the following switching modules:

• 48-port 10/100/1000-Mbps Gigabit Ethernet (RJ-45)—WS-X4548-GB-RJ45 (power-efficient) and

WS-X4448-GB-RJ45—This module, with multispeed autosensing, autonegotiating technology, provides

wiring-closet investment protection by allowing Fast Ethernet desktops to migrate to Gigabit Ethernet in the

future, without replacing the switch line cards. All 48 ports can be used at 10 Mbps, 100 Mbps, or 1000 Mbps

up to 100 meters over Category 5 copper cabling. The 48 ports can burst to Gigabit Ethernet line rate and can

share 12 Gbps of full-duplex bandwidth into the switching fabric. The amount of oversubscription can be

controlled simply by varying the number of ports used at 1000 Mbps. All ports use the standard IEEE 802.3x

flow-control (pause frame) mechanism to control Gigabit Ethernet host traffic.
