Rear Panel Description

Dual-Purpose Port LEDs

The LEDs on a dual-purpose port show whether an RJ-45 connector is connected to the port, or if an SFP module is installed in the slot. See the example in Figure 1-18. You can configure each port as either a 10/100/1000 port through the RJ-45 connector or as an SFP module, but not both at the same time. The LEDs show how the port is being used (Ethernet or SFP module).

The LED colors have the same meanings as described in Table 1-4and Table 1-5.

Cable Guard for the Catalyst 2960-8TC-L, 2960G-8TC-L, and 2960PD-8TT-L Switches

You can order an optional cable guard to secure cables to the front of the Catalyst 2960-8TC-L, 2960G-8TC-L, and 2960PD-8TT-L switches and to prevent them from being accidentally removed.

To order a cable guard, contact your Cisco representative using these part numbers:

CBLGRD-C2960-8TC: Catalyst 2960-8TC-L and Catalyst 2960PD-8TT-L switches

CBLGRD-C2960G-8TC: Cisco Catalyst 2960G-8TC switch

Rear Panel Description

The rear panels on the Catalyst 2960 switches have all or some of these features: an RJ-45 console port, a fan exhaust, an RPS connector, and an AC power connector (see Figure 1-19.) These are the exceptions:

No RPS connector: Catalyst 2960-8TC-L, 2960G-8TC-L, 2960PD-8TT-L, 2960-24-S, 2960-24TC-S, and 2960-48TC-S.

No fan: Catalyst 2960-8TC-L, 2960G-8TC-L, and 2960PD-8TT-L. The console port on these switches is on the front panel rather than on the rear panel.

AC power adapter input: Catalyst 2960PD-8TT-L switch.

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.
