Switch PoE Gigabit L2 gestito Cisco CBS220-24FP-4G — 24x Gigabit RJ-45, PoE, 56 Gbit/s, MAC 8192, montaggio a rack

Cisco CBS220-24FP-4G is a managed Layer 2 Gigabit PoE switch with 24 Gigabit RJ-45 ports, integrated Power over Ethernet (IEEE 802.3af/at) support and a switching capacity of 56 Gbps. Designed for rack mounting, it offers an 8192-entry MAC address table and implements common IEEE 802.3 and IEEE 802.1 standards for predictable, interoperable connectivity. The device is intended for small and medium business access-layer deployments where reliable Ethernet connectivity and PoE power delivery for IP phones, wireless access points and other powered devices are required.

Advantages

The switch provides managed Layer 2 features with an intuitive dashboard and security options suitable for business networks. Built-in PoE/PoE+ capability simplifies deployment of powered devices without separate power supplies. With a 56 Gbps switching capacity and support for established IEEE standards, the CBS220-24FP-4G delivers consistent packet forwarding and basic traffic control. Rack-mountable form factor and a compact, white enclosure make it easy to integrate into standard server racks and office network closets.

Suitable for

• Small and medium business access layer connectivity

How to use

Install the switch in a standard 19" rack using the included mounting brackets or place it on a stable surface in a network closet. Connect your upstream router or core switch to one of the Gigabit ports to provide network uplink and configure basic settings through the web-based dashboard or management interface. Connect PoE-capable devices such as IP phones and wireless access points to the RJ-45 ports; the switch will supply power according to IEEE 802.3af/at negotiation. Configure VLANs, QoS and security policies as needed to segment traffic, prioritise voice or video, and enforce access control.

Recommendations

Plan PoE budget per port and overall power budget before deployment to ensure the combined power draw of connected devices does not exceed the switch's available PoE power. Use VLANs and QoS to prioritise time-sensitive traffic (voice/video). Keep switch firmware updated and restrict management access using secure credentials and management VLANs.
