- Manufacturer: Cisco
- Part number: WS-C2948G-GE-TX
- Description: The Cisco Catalyst 2948G-GE-TX Gigabit Ethernet Switch is a fixed-configuration switch that provides Gigabit Ethernet connectivity for small and medium-sized networks. The Cisco 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 networking industry. The Cisco Catalyst 2948G-GE-TX is also an affordable solution for delivering gigabit-speed connectivity to the desktop over Category 5 copper cabling. The Cisco Catalyst 2948G-GE-TX has autosensing 48 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 Cisco Gigabit EtherChannel 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 Cisco Catalyst 2948G-GE-TX uses the same feature-rich Cisco Catalyst OS software as the Cisco Catalyst 2948G, the Cisco Catalyst 2980G-A, and Cisco Catalyst 4000 Series switches.
