Cisco Catalyst
4912G 12 Port Gigabit Ethernet Switch
The Catalyst 4912G is a 12-port dedicated Gigabit
Ethernet switch featuring high performance Layer
2 switching and intelligent IOS network services
for high-speed network concentration. 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 IOS network services,
capable of enhancing LAN scalability, multicasting,
security, management and QoS. The dedicated gigabit
Catalyst 4912G leverages the same feature set with
identical software code base and the same enterprise
functionality as the Catalyst 5500/5000 Series,
delivering a consistent end-to-end solution.
