New Cisco Catalyst 2948G-GE-TX
Gigabit Ethernet Switch

Product Overview

Cisco Systems® is pleased to introduce the new Cisco® Catalyst® 2948G-GE-TX Gigabit Ethernet switch, a fixed-configuration switch that provides Gigabit Ethernet connectivity for small and mid-sized networks. The Catalyst 2948G-GE-TX switch enhances network performance and productivity with the highest 10/100/1000-Mbps port density in a 1-rack unit (RU) form factor in the industry. The Catalyst 2948G-GE-TX is an affordable solution for delivering gigabit-speed connectivity to the desktop over Category 5 copper cabling.

The Catalyst 2948G-GE-TX has 48 autosensing 10/100/1000BASE-T ports and 4 Small Form-Factor Pluggable (SFP) ports, providing a total of 52 Gigabit Ethernet ports. The 4 SFP ports are wire-speed, and the 48 10/100/1000BASE-T ports can burst to Gigabit Ethernet line rate and share 12 Gbps of capacity (or 6 Gbps full-duplex) into the switching fabric. All ports can use Gigabit EtherChannel® technology or IEEE 802.3ad for high-speed interconnection applications. All ports use the standard IEEE 802.3x flow-control (PAUSE frame) mechanism to control Gigabit Ethernet host traffic. The Catalyst 2948G-GE-TX uses the same Catalyst OS software as the Catalyst 2948G and Catalyst 2980G-A switches and the Catalyst 4000 Series Switch.
