Managed L2 Gigabit PoE Switch Cisco CBS220-24P-4X — 24x 10/100/1000 RJ‑45, 4x SFP+, 128 Gbit/s, 8192 MAC

Cisco CBS220-24P-4X is a managed Layer 2 Gigabit PoE switch designed for small and medium business networks. It includes 24 10/100/1000 RJ‑45 ports with Power over Ethernet (IEEE 802.3af/at) and four SFP+ uplink ports. The switch provides a 128 Gbit/s switching capacity and an 8192-entry MAC address table, supports common Layer 2 features and is rack-mountable for deployment in standard network racks.

Advantages

The CBS220-24P-4X combines PoE support on 24 Gigabit ports with four SFP+ uplinks to simplify deployment of IP phones, wireless access points and edge aggregation. Its managed Layer 2 feature set and 8192 MAC table provide predictable behavior in converged voice, video and data environments. A 128 Gbit/s switching capacity ensures non-blocking throughput in typical SMB topologies while rack-mountable design enables integration into existing cabinets.

Suitable for

• Small and medium business office networks
• Powering and connecting IP phones and PoE wireless access points
• Edge aggregation and uplink connectivity to core switches or servers
• Converged voice, video and data deployments

Key specifications

• Ports: 24 × 10/100/1000 RJ‑45 with PoE support
• Uplinks: 4 × SFP+ ports (10 Gbps capable)
• Switching capacity: 128 Gbit/s
• MAC address table size: 8192 entries
• PoE standards supported: IEEE 802.3af and IEEE 802.3at
• Form factor: rack-mountable

How to use

Install the switch in a standard 19-inch rack or place it on a stable surface following the included mounting instructions. Connect your Gigabit devices to the RJ‑45 ports and connect uplinks via the SFP+ ports using compatible SFP+ transceivers and fibre or direct-attach cables. Configure network settings, VLANs, QoS and PoE priorities through the device’s management interface or the Cisco Business dashboard according to your network design. Monitor port status and PoE budget to ensure connected devices receive required power.

Recommendations

Plan PoE power allocation before deployment: calculate total PoE budget based on attached devices and reserve capacity for future expansion. Use SFP+ uplinks for high-capacity connections to core switches or servers, and apply VLAN and QoS settings to separate and prioritize voice, video and data traffic for predictable performance.
