The Cisco

 2948G-GE-TX

Gigabit Ethernet Switch is a

fixed-configuration switch that provides

Gigabit Ethernet connectivity for small

and medium-sized networks (Figure 1).

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.

Today’s knowledge workers are placing

higher demands on their networks.

They need to run multiple, concurrent

applications, and to do this productively,

they require higher bandwidth from the

network. For example, a worker joins a

team conference call using IP

videoconferencing, sends a 10-MB

spreadsheet to meeting participants,

broadcasts the latest marketing video for

the team to evaluate, and queries the

customer relationship management (CRM)

database for the latest real-time feedback.

Meanwhile, the multigigabyte system

backup starts in the background and the

latest virus updates are pushed to the

client. Bandwidth enhancement beyond

100 Mbps—enabled by Gigabit

Ethernet—provides for a smoothly

operating network that can evolve.

Cisco makes the transition to Gigabit

Ethernet faster and easier with a full suite

of Gigabit Ethernet products including

the Catalyst 3750 Series switches and

the Catalyst 2970 Series switches. The

Catalyst 3750 Series switches are an

innovative product line that improves

LAN operating efficiency by combining
