Chapter 2 Switch Installation (24- and 48-Port Switches)

Installing and Removing SFP Modules

After the switch is mounted on the wall, do these tasks to complete the installation:

Power on the switch. See the “Verifying Switch Operation” section on page 2-7.

Connect to a 10/100 or 10/100/1000 port, and run Express Setup. See the Catalyst 2960 Switch Getting Started Guide for instructions.

Connect to the front-panel ports. See the “Connecting to the 10/100 and 10/100/1000 Ports” section on page 2-18, the “Connecting to SFP Modules” section on page 2-19, and the “Connecting to a Dual-Purpose Port” section on page 2-22to complete the installation.

For configuration instructions about using the CLI setup program, go to Appendix C, “Configuring the Switch with the CLI-Based Setup Program.”

Table- or Shelf-Mounting

This section applies to all switches except the Catalyst 2960-8TC-L, Catalyst 2960G-8TC-L, and Catalyst 2960PD-8TT-L switches. For information applicable to those switches, see Chapter 3, “Switch Installation (8-Port Switches).”

Follow these steps to install the switch on a table or shelf:

Step 1 Locate the adhesive strip with the rubber feet in the mounting-kit envelope. Attach the four rubber feet to the recessed areas on the bottom of the unit.

Step 2 Place the switch on the table or shelf near an AC power source.

After the switch is mounted on the table, do these tasks to complete the installation:

Power on the switch. See the “Verifying Switch Operation” section on page 2-7.

Connect to a 10/100 or 10/100/1000 port, and run Express Setup. See the Catalyst 2960 Switch Getting Started Guide for instructions.

Connect to the front-panel ports. See the “Connecting to the 10/100 and 10/100/1000 Ports” section on page 2-18,“Connecting to SFP Modules” section on page 2-19and the “Connecting to a Dual-Purpose Port” section on page 2-22to complete the installation.

For configuration instructions about using the CLI setup program, go to Appendix C, “Configuring the Switch with the CLI-Based Setup Program.”

Note When the connectors are not being used, replace the dust covers on them for protection.

Installing and Removing SFP Modules

These sections describe how to install and remove SFP modules. SFP modules are inserted into SFP module slots on the front of the Catalyst 2960 switches. These field-replaceable modules provide the uplink optical interfaces, laser send (TX) and laser receive (RX).

You can use any combination of SFP modules. Refer to the Catalyst 2960 switch release notes for the list of SFP modules that the Catalyst 2960 switch supports. Each SFP module must be of the same type as the SFP module on the other end of the cable, and the cable must not exceed the stipulated cable length for reliable communications. See the “SFP Module Cable Specifications” section on page A-4for cable

2960 specifications

Cisco Systems 2960 series switches are a prominent solution in the networking landscape, known for their reliability, scalability, and feature-rich offerings. Ideal for small to medium-sized enterprises, these switches provide a robust foundation for network infrastructure, ensuring optimal performance and connectivity.

One of the standout features of the Cisco 2960 series is its Layer 2 switching capabilities. The switches support multiple VLANs (Virtual Local Area Networks), allowing network administrators to segment traffic efficiently and enhance security protocols. This is crucial in modern networks where managing traffic and isolating sensitive information is a priority.

The Cisco 2960 series also incorporates advanced Quality of Service (QoS) features, enabling the prioritization of critical applications and services. This functionality ensures that time-sensitive data, such as voice and video traffic, maintains a high quality of service even in congested networks. With support for IEEE 802.1p and DSCP marking, administrators can fine-tune their network performance to meet specific organizational needs.

Power over Ethernet (PoE) is another significant characteristic of the Cisco 2960 series. This feature allows switches to deliver electrical power alongside data over Ethernet cables to devices such as IP phones, wireless access points, and surveillance cameras. With PoE, organizations can reduce clutter from power cables and increase deployment flexibility for various devices.

In terms of security, the Cisco 2960 series is equipped with a range of integrated security features. The switch supports port security, 802.1X authentication, and Access Control Lists (ACLs), providing robust defenses against unauthorized access and potential network vulnerabilities. These security measures are essential for protecting sensitive data and ensuring compliance with industry regulations.

Moreover, the Cisco 2960 series offers enhanced network management capabilities with Cisco's Intelligent Network Services. This includes support for Simple Network Management Protocol (SNMP), Cisco Prime, and Embedded Event Manager (EEM), allowing for efficient monitoring, troubleshooting, and policy enforcement across the network.

Additionally, the Cisco 2960 switches provide various models and configurations, catering to different networking needs. Options include models with varying port densities, uplink configurations, and stacking capabilities, making it easy for organizations to choose solutions that align perfectly with their requirements.

In summary, the Cisco 2960 series is a versatile and essential component of modern networking environments. Its advanced features, including Layer 2 support, QoS, PoE, robust security, and diverse management tools, make it an excellent choice for organizations looking to build a strong and secure network infrastructure.
