Catalyst 4912G Switch

High-Performance Gigabit Ethernet Aggregator

Overview

The Catalyst

4912G is a 12-port dedicated Gigabit Ethernet

switch featuring high-performance Layer 2 switching and

intelligent Cisco IOS

network services for high-speed

network aggregation. The Catalyst 4912G is the flagship

product of the new Catalyst 4900 series, which delivers fixed

configuration enterprise platforms providing cost-effective,

high-performance solutions for Gigabit networking. The

Catalyst 4912G switch provides an advanced enterprise

switching solution delivering low-cost, high-density gigabit

aggregation with modular Gigabit Interface Converter

(GBIC) modular protection. The Catalyst 4912G switch

provides intelligent Cisco IOS network services, capable of

enhancing LAN scalability, multicasting, security,

management and quality of service (QoS). The dedicated

gigabit Catalyst 4912G leverages the same feature set with

identical software code base and the same enterprise

functionality as the Catalyst 5000 family, delivering a

consistent end-to-end solution.

The Catalyst 4000 family benefits include:

• Powerful wire-speed performance with 24 Gbps of

dedicated bandwidth for nonblocking Gigabit Ethernet

concentration

• Consistent and mature Catalyst 5000 family software

compatibility

• Future-proof bandwidth protection with broad Gigabit

EtherChannel

availability

• GBIC flexibility on fiber port interfaces covering a wide

range of cabling distances

• Redundant, hot-swappable external power supply (option)

and other fault-tolerant features

The Catalyst 4900 series fixed-configuration gigabit

solutions extend and advance the rich Ethernet heritage

pioneered by the popular Catalyst 2900 10/100 switches.

The Catalyst 4912G leverages the powerful hardware

switching fabric (ASICs) of the modular Catalyst 4000

switch family, plus offers the low entry-cost benefit of a fixed

configuration form factor. The Catalyst 4912G broadens the

Cisco Gigabit product offering, underscoring a continued

investment in expanding the scope of Gigabit Ethernet

solutions and further reducing the price-per-port of leading

Gigabit solutions (now under $1350 per port list).

The Cisco Catalyst solution provides a greater breadth

and depth of switching solutions than ever before to meet

your entire network’s needs.

The Catalyst 4912G switch is orderable now and

available in March 1999.
