Sieťový switch Cisco CBS220-24T-4X — Managed L2, 24x Gigabit (10/100/1000) RJ-45, 4x 10G SFP+

The Cisco CBS220-24T-4X is a managed Layer 2 network switch designed for small to medium office networks, aggregation and edge switching. It provides 24 Gigabit RJ-45 ports (10/100/1000) for copper connectivity and four 10G SFP+ uplink ports for high-bandwidth links. The switch delivers a switching capacity of 128 Gbit/s and supports an address table of up to 8,192 MAC addresses, making it suitable for consolidating wired devices, servers and uplinks in a business-class environment. The product comes in a rack-mountable white chassis and implements industry-standard protocols for interoperability and security.

Advantages

The CBS220-24T-4X offers managed Layer 2 features with an intuitive dashboard and a set of standards-based functions such as 802.1x authentication and 802.3ad link aggregation. With four 10G SFP+ uplinks it supports higher-speed aggregation to core switches or servers, while the 24 Gigabit RJ-45 ports provide reliable access-layer connectivity. The switch's supported networking standards include QoS and flow control mechanisms that help maintain predictable performance for converged data, voice and video traffic. Rack-mount capability and a compact weight make it practical to install in standard server cabinets.

Suitable for

• Small and medium office networks requiring managed access switching
• Edge or aggregation switching with 10G uplink needs
• Deployments that require IEEE 802.1x authentication and link aggregation
• Environments where consolidated data, voice and video traffic is delivered over a converged network

How to use

Install the switch in a standard 19-inch rack or place it on a flat surface according to the site layout. Connect access devices to the 24 Gigabit RJ-45 ports and use the 10G SFP+ ports for uplinks to core switches or servers using compatible SFP+ modules and fiber or direct-attach cables. Power the device and access the management interface through the web dashboard or supported management tools to configure VLANs, link aggregation, 802.1x authentication and QoS policies. Apply firmware updates and save configuration backups after completing setup.

Recommendations

For reliable operation, use structured cabling and Ethernet cables rated for Gigabit performance (Cat5e or higher). When planning uplinks, choose SFP+ modules that match your fiber type or direct-attach cable specifications. Enable link aggregation for critical uplinks to increase throughput and redundancy, and configure 802.1x where endpoint authentication is required. Regularly review firmware updates and maintain configuration backups to ensure stability and security.
