Chapter 2 Switch Installation

Planning a Switch Stack

Verifying Switch Operation

Before you install the switch in a rack, on a wall, or on a table or shelf, power on the switch and verify that it passes POST.

To power on the switch, plug one end of the AC power cord into the switch AC power connector, and plug the other end into an AC power outlet.

As the switch powers on, it begins the POST, a series of tests that runs automatically to ensure that the switch functions properly. LEDs can blink during the test. POST lasts approximately 1 minute. When the switch begins POST, the System, RPS, Status, Duplex, and Speed LEDs turn green. The System LED blinks green, and the other LEDs remain solid green.

When the switch completes POST successfully, the System LED remains green. The RPS LED remains green for some time and then reflects the switch operating status. The other LEDs turn off and then reflect the switch operating status. If a switch fails POST, the System LED turns amber.

POST failures are usually fatal. Call Cisco technical support representative if your switch fails POST.

After a successful POST, unplug the power cord from the switch. Install the switch in a rack, on a wall, on a table, or on a shelf as described in the “Installing the Switch” section on page 2-10.

If your configuration has an RPS, connect the switch and the RPS to different AC power sources. See the Cisco RPS documentation for information.

Note When you connect the RPS to the switch, put the RPS in standby mode. Set the RPS to active mode during normal operation.

Warning Attach only the following Cisco RPS model to the RPS receptacle: PWR-RPS2300 = Statement 370

Planning a Switch Stack

Note This section applies only to the Catalyst 2960-S stacking-capable switches.

Stack Guidelines

Connect only Catalyst 2960-S switches in a switch stack. You cannot stack the Catalyst 2960-S with other switches such as the Catalyst 2975, 3550, 3560, or 3750 switches.

Stack only up to four switches.

Install the FlexStack module and the FlexStack cable. You can order them from your Cisco sales representative: C2960S-STACK=.

Note The FlexStack module is hot-swappable and can be inserted while the switch is powered on.

Order the appropriate cable from your Cisco sales representative. The length of FlexStack cable depends on your configuration. These are the different sizes available:

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.
