Cisco Catalyst 2980G-A Switch
DISCONTINUED REPLACEMENT IS Cisco Catalyst 4503, Cisco Catalyst 3550-24 & 3550-48,  Cisco Catalyst 2948G-GE-TX

The Catalyst 2980G features:

• Dedicated 80-port, 10/100 Mbps Ethernet and two-port, 1000BaseX Gigabit Ethernet with flexible media interfaces
• Feature-rich enterprise Catalyst system software with advanced Cisco IOS network services
• Comprehensive management tools based on standard CiscoWorks2000 applications
• 24 Gbps non-blocking switch fabric
• 18 million packets-per-second forwarding rate
• EtherChannel, UplinkFast, PortFast and other fault-tolerant features

The Cisco Catalyst 2980G-A replaces the 2980G, and is identical, with additional features:

• New Internal AC power supply
• Support for the new Cisco optional external Redundant Power System 300 (RPS 300)
• 10/100 console port
• Minimum software dependency of Catalyst OS version 6.1(1)

Key Benefits:

• Reduced Network Operational Expenses---Simplified Configuration with high port-density minimizes set-up and maintenance configuration difficulty, compared to using numerous lower density switches to network the same number of desktops.
• Single IP Address along with Web-based management interface (option)---offers quick plug-n-play network insertion.
• Consistent Catalyst Software compatibility---provides enterprise feature, Command Line Interface, and default value consistency with the Cisco Catalyst 2948G switching solution for lower cost of ownership and maintenance.
• Performance---Layer 2 switching delivers a fast 18 million packets-per-second (pps) powered by a 24 Gbps engine.
• Density---The Catalyst 2980G reduces complexity and easily supports the changing desktop environments of today's small- and medium-wiring closets.
• Cisco IOS Network Services---Catalyst 2980G switch provides mature enterprise Layer 2 features capable of enhancing corporate networks. These features meet the needs of small- and medium-businesses because they have been improved based on years of customer feedback.
• Hardware-Based Multicasting---Cisco Group Multicast Protocol (CGMP) supports efficient multimedia networking.
• Cost-effective---Delivering advances in engineering and manufacturing, the Catalyst 2980G solution redefines a new price/performance value for fixed configuration, high-density switching.
• Shared Memory Architecture, No Head-of-Line Blocking---The low-latency, centralized, shared memory switching fabric architecture assures leading-edge capabilities and eliminates any possibility of head-of-line blocking.
• Differentiated Quality of Service (QoS)---mission critical traffic prioritization is supported with dual queues per port, allowing differentiated network traffic based on user/administrator defined priorities with standards-based 802.1P compatibility.
• High Availability---standards based Virtual LAN (VLAN) support with standards-based 802.1Q tagging, Spanning Tree Protocol (802.1D) along with Cisco enhancements for STPV, UplinkFast, PortFast, etc. assures maximum up-time and fault recovery.
