Cisco Catalyst 2950 Switches with Standard Image (SI) Software

Product Overview

The Cisco Catalyst® 2950SX-24, 2950-24 and 2950-12, members of the Cisco Catalyst 2950 Series Switches, are

standalone, ﬁxed-conﬁguration, managed 10/100 switches providing basic workgroup connectivity for small to midsized

networks. These wire-speed desktop switches come with Standard Image (SI) Software features and offer Cisco IOS

functionality for basic data, video and voice services at the edge of the network. Embedded in all Catalyst 2950 Series is the

Cisco Cluster Management Suite (CMS) Software, which allows users to simultaneously conﬁgure and troubleshoot multiple

Catalyst desktop switches using a standard Web browser.

This product line offers two distinct sets of software features and a range of conﬁgurations to allow small, midsized, and

enterprise branch ofﬁces to select the right combination for the network edge. The SI software offers Cisco IOS functionality

for basic data, video, and voice services. For networks with requirements for additional security, advanced quality of service

(QoS), and high availability, the Enhanced Image (EI) software delivers intelligent services such as rate limiting and security

ﬁltering for deployment at the network edge.

The Catalyst 2950SX-24, 2950-12, and 2950-24 switches are only available with the SI software for the Catalyst 2950 Series.

• Catalyst 2950SX-24 Switch — 24 10/100 ports with 2 ﬁxed 1000BASE-SX uplinks

• Catalyst 2950-24 Switch — 24 10/100 ports

• Catalyst 2950-12 Switch — 12 10/100 ports

These switches provide customers with a choice of connectivity options. While the Catalyst 2950-12 and 2950-24 provide

12 and 24 10/100 ports for edge connectivity respectively, the Catalyst 2950SX-24 provides 24 10/100 ports and 2 integrated

1000BASE-SX ports for gigabit uplink connectivity over ﬁber. With these integrated ports, customers get an extremely cost-

effective solution for delivering gigabit speeds using ﬁber. Dual ports also provide redundancy and increased availability, as

well as provide a cost-effective means for cascading switches and managing them as a cluster. This switch is ideal for

education and government segments, where ﬁber uplinks are a requirement.

Other Catalyst 2950 Series Switches

The Catalyst 2950 Series Intelligent Ethernet Switches with EI Software are also part of the Catalyst 2590 Series switches.

These ﬁxed-conﬁguration, stackable models bring intelligent services, such as advanced QoS, enhanced security, and high

availability to the network edge — while maintaining the simplicity of traditional LAN switching. When a Catalyst 2950

Intelligent Ethernet Switch is combined with a Catalyst 3550 Series Switch, the solution enables IP routing from the edge to

the core of the network. Refer to the Catalyst 2950 Series EI Data Sheet for more information.

Catalyst 2950 Long-Reach Ethernet (LRE) Switches

• Catalyst 2950ST-24-LRE — 24 Long-Reach Ethernet (LRE) ports and 2 ﬁxed 10/100/1000BASE-T ports and 2 Small

Form Factor Pluggable (SFP) ports (two of the four uplinks active at one time)

• Catalyst 2950ST-8-LRE — Eight LRE ports and two ﬁxed 10/100/1000BASE-T ports and two SFP ports (two of the four

uplinks active at one time)

The Cisco Catalyst 2950 LRE solution delivers cost-effective, high-performance broadband access over existing phone

wiring in enterprise campus environments and multitenant buildings (for example, hotels, apartment buildings, and ofﬁce

buildings). The Catalyst 2950 LRE switches come with the EI Software features enabling enterprise and service provider

customers to extend intelligent services over legacy wiring (category 1/2/3) to distances up to 5000 feet. Cisco is the only

company with the breadth of technologies that allow customers to deliver intelligent network services across any

combination of wired and wireless infrastructures. Refer to the Catalyst 2950 LRE Series Data Sheet for more

information.
