Cisco Catalyst 2960G-48TC Managed Ethernet Switch

The Cisco Catalyst 2960G-48TC is a fixed-configuration, managed Ethernet switch designed to power entry‑level enterprise networks, branch offices, and mid‑market deployments with dependable Gigabit connectivity. As a member of the renowned Cisco Catalyst 2960 Series, the 2960G-48TC delivers robust Layer 2 switching capabilities, secure access controls, and straightforward management in a compact 1U form factor. It’s built for reliability in tight spaces, offering desktop and rack‑mount versatility that helps network administrators deploy scalable networks without the complexity of larger chassis switches. Whether you’re building a new campus edge or upgrading a remote office, this switch provides a solid foundation for fast, predictable Ethernet performance.

• 48 x 10/100/1000 Ethernet ports with auto-negotiation and auto-MDIX: A dense port count enables quick, flexible connections for desktops, printers, IP phones, and other edge devices. Auto‑negotiation ensures optimal speed and duplex settings, while auto‑MDIX eliminates the need to worry about straight‑through versus crossover cables during initial provisioning.
• 2 x 1-Gigabit uplink SFP ports: Two dedicated uplink ports allow you to connect to distribution switches, aggregation layers, or core networks over fiber or copper wherever your layout requires. This uplink strategy supports scalable growth and network segmentation while preserving full access port bandwidth for user devices.
• Layer 2 switching with VLANs and 802.1Q tagging: Segment networks into logical VLANs to improve security, reduce broadcast domains, and optimize traffic flow. 802.1Q tagging ensures seamless trunking between switches, enabling efficient cross-branch interoperability and centralized policy enforcement.
• Quality of Service (QoS) and traffic prioritization: Prioritize voice, video, and business-critical data with QoS policies that help maintain call clarity, minimize video stutter, and improve application responsiveness in busy networks. Traffic classification and policy enforcement ensure predictable performance for time‑sensitive apps.
• Comprehensive security and policy controls: Implement ACLs, port security, and granular access controls to protect the network edge. Centralized policy enforcement helps safeguard sensitive resources and restrict unauthorized devices from accessing critical segments.

How to install Cisco Catalyst 2960G-48TC

• Plan your layout: Determine the best location for the switch in a standard 19" rack or on a stable shelf with proper ventilation. Verify clearance for cooling and accessibility to the console port for initial configuration.
• Mount and power: Mount the switch securely in the rack using the supplied mounting hardware. Connect the power cord to a reliable power source and verify that the power indicator is active. Ensure the environment meets the operator’s ambient temperature and airflow recommendations.
• Cable the ports: Connect edge devices (PCs, IP phones, printers) to the 48 RJ-45 ports. Use the two SFP uplinks to connect to your distribution or core layer, selecting fiber or copper modules as appropriate for your network design.
• Initial configuration: Connect a management workstation to one of the switch’s data ports or the console port for direct CLI access. Use the Cisco IOS CLI to configure basic management settings, including a strong admin password, hostname, and IP management address if you plan to manage the switch remotely. Disable unneeded services such as Telnet in favor of SSH for secure remote management.
• Configure VLANs and security: Create the required VLANs, assign access ports to the appropriate VLANs, and configure 802.1Q trunking on the uplink ports. Apply ACLs and port security as needed to protect the device and enforce your access policies. Save the running configuration to startup configuration to ensure changes persist after a reboot.
