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

Preparing for Installation

These standards provide guidelines for acceptable working environments and acceptable levels of suspended particulate matter:

Network Equipment Building Systems (NEBS) GR-63-CORE

National Electrical Manufacturers Association (NEMA) Type 1

International Electrotechnical Commission (IEC) IP-20

This precaution applies to all Catalyst 2960 switches except for the Catalyst 2960-8TC, 2960G-8TC, and 2960PD-8TT-L switches.

Installation Guidelines

This section does not apply to the Catalyst 2960-8TC, 2960G-8TC, and 2960PD-8TT-L switches. For information applicable to those switches, see Chapter 3, “Switch Installation (8-Port Switches).”

When you determine where to place the switch, be sure to observe these requirements:

For 10/100/1000 ports, cable lengths from the switch to connected devices must be no longer than 328 feet (100 meters).

The cables meet the specifications in Table A-1 on page A-5, which lists the cable specifications for 1000BASE-X and 100BASE-X SFP modules available for the Catalyst 2960 switch. Catalyst 2960 switch SFP ports can use both GLC-GE-100XX and GLC-FE-100XX SFP modules.

When you use shorter lengths of single-mode fiber cable, you might need to insert an inline optical attenuator in the link to avoid overloading the receiver.

When the fiber-optic cable span is less than 15.43 miles (25 km), you should insert a 5-decibel (dB) or 10-dB inline optical attenuator between the fiber-optic cable plant and the receiving port on the 1000BASE-ZX SFP module at each end of the link.

The operating environment must be within the ranges listed in Appendix B, “Technical Specifications.”

Clearance to front and rear panels meets these conditions:

You can easily read the front-panel indicators.

Access to ports is sufficient for unrestricted cabling.

The rear-panel power connector is within reach of an AC power receptacle.

Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent lighting fixtures. Make sure the cabling is safely away from other devices that might damage the cables.

Airflow around the switch and through the vents is unrestricted.

Temperature around the unit does not exceed 113°F (45°C).

If the switch is installed in a closed or multirack assembly, the temperature around it might be greater than normal room temperature.

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.
