Overview of the CBS220-24FP-4X-AU

The ​​CBS220-24FP-4X-AU​​ is a ​​24-port managed Gigabit PoE+ switch​​ from Cisco’s Business 220 series, designed for ​​demanding environments​​ requiring high-speed uplinks and scalable power delivery. With ​​four 10G SFP+ ports​​ and a robust PoE budget, it caters to data-intensive applications like multi-campus surveillance, high-density Wi-Fi 6 deployments, or converged voice/video/data networks.

Key Technical Specifications

• ​​Ports​​: 24 × 10/100/1000 Mbps RJ45 (PoE+), 4 × 10G SFP+ uplinks.
• ​​PoE Budget​​: ​​400W total​​ (30W per port, IEEE 802.3at/af compliant).
• ​​Uplink Capacity​​: ​​40Gbps aggregate​​ via 10G SFP+ ports for backbone connectivity.
• ​​Management​​: ​​Layer 2+ features​​ including static routing, VLANs, QoS, and SNMPv3.
• ​​Security​​: ​​MACsec encryption​​, 802.1X authentication, and ACLs for network hardening.

Why the CBS220-24FP-4X-AU Stands Out

Compared to switches with 1G uplinks, this model addresses bottlenecks in bandwidth-heavy scenarios:

• ​​10G Uplinks​​: Eliminate congestion when aggregating traffic from multiple switches or connecting to core networks.
• ​​Future-Proof PoE​​: Supports ​​802.3bt (UPoE)​​ readiness for next-gen IoT devices requiring up to 90W per port.
• ​​Hybrid Stacking​​: Use Cisco FlexStack to combine up to 8 switches into a single management domain.

Addressing Critical User Concerns

​​Q: Can this switch fully power 24 PoE+ devices?​​
A: No. The ​​400W budget​​ supports ~13 ports at 30W. Balance high-power (e.g., 25W APs) and low-power devices (e.g., 7W VoIP phones) for optimal usage.

​​Q: Are the 10G SFP+ ports backward-compatible with 1G modules?​​
A: Yes. They support ​​1G/10G SFP/SFP+ transceivers​​, allowing gradual upgrades to 10G infrastructure.

​​Q: Does it support Layer 3 routing?​​
A: Limited to ​​static routing​​ for basic inter-VLAN traffic. For dynamic routing, consider Cisco Catalyst switches.

Where to Purchase the CBS220-24FP-4X-AU

Practical Deployment Insights

Deploying the CBS220-24FP-4X-AU in a university’s campus Wi-Fi rollout, the ​​10G uplinks handled 800+ concurrent users​​ without latency spikes, while PoE+ powered 18 Wi-Fi 6 APs. The switch’s ​​MACsec encryption​​ also secured sensitive research data traversing the network. While not a Catalyst-tier device, its ​​balance of cost and performance​​ makes it ideal for mid-market organizations eyeing 10G readiness—skipping it often leads to premature infrastructure overhauls.
