Q. What is the Cisco
® 2948G-GE-TX Switch?
A. The Cisco Catalyst 2948G-GE-TX Switch is a fixed-configuration switch that provides Gigabit Ethernet connectivity for small and midsized networks. It enhances network performance and productivity with 52 10/100/1000-Mbps ports in a 1 rack unit (RU) form factor. The Catalyst 2948G-GE-TX is also an affordable solution for delivering gigabit-speed connectivity to the desktop over Category 5 (Cat5) copper cabling. The Catalyst 2948G-GE-TX has 48 10/100/1000BASE-T ports and 4 Small Form-Factor Pluggable (SFP) ports.
Q. Which SFP uplinks does the Cisco Catalyst 2948G-GE-TX support?
A. The following SFP uplinks are supported: 1000BASE-SX, 1000BASE-LX/LH, 1000BASE-ZX, 1000BASE-T, and coarse wavelength-division multiplexing (CWDM) SFP uplinks.
Q. Does the Cisco Catalyst 2948G-GE-TX Switch interoperate with SFP uplinks from other vendors?
A. No. Similar to other Cisco switches and routers, the Cisco Catalyst 2948G-GE-TX Switch does not interoperate with other vendors' SFP uplinks. The switch will shut down the port if an SFP uplink provided by a vendor other than Cisco Systems
® is inserted.
Q. What are the minimum software requirements of the Cisco Catalyst 2948G-GE-TX?
A. The Catalyst 2948G-GE-TX is based on Catalyst OS software 8.2(1)GLX. The Catalyst 2948G-GE-TX uses the same feature-rich Catalyst OS software as the Catalyst 2948G, the Catalyst 2980G-A, and the Catalyst 4000 Series Switches.
Q. Does the Cisco Catalyst 2948G-GE-TX operate at wire-speed?
A. 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 utilize Cisco 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.
Q. Where would I deploy a Cisco Catalyst 2948G-GE-TX?
A. The Catalyst 2948G-GE-TX is designed for deployment in small and midsized workgroups requiring Gigabit Ethernet connectivity. It is ideal for deployments that require an inherently higher burst rate, such as "gigabit to the desktop" installations.
Q. What are the other Cisco Catalyst 2900 Series Switches?
A. The Cisco Catalyst 2900 Series has industry-leading highest-density, small-form factor, fixed-configuration switches, offering feature-rich, end-to-end software and solutions for workgroup and wiring closets.
Q. For which fixed-configuration and stackable Cisco Catalyst switch product series can I obtain a "no additional cost" Cisco IOS Software update?
A. Cisco offers ongoing Cisco IOS Software updates for the following fixed-configuration and stackable Cisco Catalyst switch product series at no additional cost. For the life of the product, updates within the Cisco IOS package purchased (such as LAN Base, IP Base, IP Services, etc.) will be made available to customers.
• Cisco Catalyst Express 500 Series Switches
• Cisco Catalyst 2900 XL Series Switches
• Cisco Catalyst 2940 Series Switches
• Cisco Catalyst 2948G-GE-TX Series Switch
• Cisco Catalyst 2950 Series Switches
• Cisco Catalyst 2950 LRE Series Switches
• Cisco Catalyst 2955 Series Switches
• Cisco Catalyst 2960 Series Switches
• Cisco Catalyst 2970 Series Switches
• Cisco Catalyst 3500 XL Series Switches
• Cisco Catalyst 3550 Series Switches
• Cisco Catalyst 3560 Series Switches
• Cisco Catalyst 3750 Series Switches
• Cisco ME 2400 Series Ethernet Access Switches

upgrades are different from
updates. For example, an upgrade from the IP Base Package to the IP Services Package provides significant new functions; therefore, this upgrade requires the purchase of a software license upgrade. Updates are incremental software features and bug fixes that are released within a Cisco IOS package for which you own a license.
This statement supersedes any previous warranty or software statement and is subject to change without notice.
Q. How do I get a "no additional cost" Cisco IOS Software update for my fixed-configuration and/or stackable Cisco Catalyst switch?
A. Customers that own a software license for any of the aforementioned fixed-configuration and/or stackable Cisco Catalyst switch product series (listed previously) may obtain a software update at the Cisco.com Website.
