Explanation in Detail
In general, Cisco switches? models are started with WS-. WS-C means the switch products and the products with WS-X begining refer to the engines or modules of switches. In addition, there is WS-G which means the Gigabit fiber optic transceiver modules of switches. Now, I explain the detailed meaning of each letter in the model through a few of examples.
W ? stands for IPSEC 40bit encryption;
S ? means switchboard;
C ? means the fixed-configuration switch;
3650 ? refers to the seires;
G ? means all the interfaces are supported Gigabit or more. If there is no letter ?G? here, it shows that the mainly port of this switch is 10/100M or 100M;
24 ? here means there are 24 ports of this switch;
T ? stands for port of BaseT port; sometimes, there is letter ?P? here which means BaseT port which supports PoE at the same time;
S ? the S behind T means the extended interface is SFP type interface and uplink;
Note: There are also ?D? or ?C? or ?W?repalcing ?T? or ?S? here, which respectively means 10Gigabit Ethernet XENPAK port and uplink, T/SPF and uplink, Integrated wireless LAN controller(50 support for up to 50 access points). Some combination meaning as following:
TT ? common port and uplink port are both BaseT;
LC ? common port is BaseT and partially support PoE(4 ports) uplink port are BaseT/SFP;
PC ? common port is BaseT and all support PoE(24 ports) uplink port are BaseT/SFP;
TC ?common port is BaseT and uplink port are all BaseT/SFP;
TS ? common port is BaseT and uplink port are all SFP;
PS ? common port is BaseT and all support the PoE, uplink port are all SFP;
FS ? common port is 100BaseFX and uplink port are all SFP;
when there is only T, it means there is no uplink port in the switch.
CISCO CATALYST 2950 SERIES SWITCHES WITH STANDARD IMAGE SOFTWARE
The Cisco® Catalyst® 2950SX48, 2950T-48, 2950SX-24, 2950-24, and 2950-12 switches, members of the Cisco Catalyst 2950 Series, are standalone, fixed-configuration, managed 10/100 Mbps switches providing basic workgroup connectivity for small to midsize networks. These wire-speed desktop switches come with Standard Image software features and offer Cisco IOS® Software functions for basic data, voice, and video services at the edge of the network.
Embedded in all Cisco Catalyst 2950 Series switches is the Cisco Device Manager software, which allows users to easily configure and monitor the switch using a standard Web browser, eliminating the need for more complex terminal emulation programs and knowledge of the command-line interface (CLI). Customers can easily initialize the switch with web-based Cisco Express Setup, without using the CLI. In addition, with Cisco Network Assistant, a standalone network management software, customers can simultaneously configure and troubleshoot multiple Cisco Catalyst desktop switches. Cisco Device Manager, Cisco Express Setup, and Cisco Network Assistant reduce the cost of deployment by enabling less-skilled personnel to set up switches quickly. Furthermore, Cisco Catalyst 2950 Series switches provide extensive management tools using Simple Network Management Protocol (SNMP) network management platforms such as CiscoWorks.
This product line offers two distinct sets of software features and a range of configurations to allow small, midsize, and enterprise branch offices to select the right combination for the network edge. For networks that require additional security, advanced quality of service (QoS), and high availability, Enhanced Image software delivers intelligent services such as rate limiting and security filtering for deployment at the network edge.
The Cisco Catalyst 2950SX-48, 2950T-48, 2950SX-24, 2950-24 and 2950-12 switches (Figures 1-5) are available only with the Standard Image (SI) software for the Cisco Catalyst 2950 Series. They cannot be upgraded to the Enhanced Image (EI) software.
