CBS220-48T-4X-NA: A High-Port-Count PoE Switch Built for North America?

​​CBS220-48T-4X-NA Overview​​

The ​​CBS220-48T-4X-NA​​ is a ​​Cisco Business Switch​​ optimized for North American markets, offering ​​48 Gigabit Ethernet ports with PoE+​​ and ​​four 1G SFP uplinks​​. Designed for medium-sized businesses, it caters to environments like retail stores, warehouses, or offices needing scalable Power over Ethernet for IP cameras, wireless APs, or VoIP phones.

​​Core Hardware & Performance​​

• ​​48 x Gigabit PoE+ ports​​ (IEEE 802.3af/at compliant).
• ​​4 x 1G SFP slots​​ for fiber connectivity or uplink stacking.
• ​​740W total PoE budget​​ (15.4W per port maximum).
• ​​Layer 2 management​​: VLANs, QoS, and IGMP snooping.
• ​​Compliance​​: FCC, UL, and Energy Star certifications for North America.

​​Answering Critical User Questions​​

​​Q: Can this switch deliver PoE to all 48 ports simultaneously?​​

​​A:​​ The ​​740W total PoE budget​​ allows full utilization, but practical limits apply. For example, 48 devices drawing 12W each (e.g., basic IP phones) would consume 576W, leaving 164W for high-power devices like 30W APs. ​​Prioritize low-power devices​​ to avoid overloading the budget.

​​Q: Is it suitable for outdoor or industrial deployments?​​

​​A:​​ No. The CBS220-48T-4X-NA is designed for ​​indoor commercial use​​ (0°C to 45°C operating temperature). For harsh environments, consider ruggedized switches with IP-rated enclosures.

​​Q: How does it differ from the CBS220-48P-4X-SP?​​

​​A:​​ The “48T” model uses ​​standard RJ45 ports​​, while “48P” variants may include combo ports (RJ45 + SFP). Both share a 740W PoE budget, but the ​​48T-4X-NA​​ is region-locked for North American voltage (120V) and certifications.

​​Why This Switch Works for NA Businesses​​

• ​​High-density PoE​​: Streamlines deployments for IoT and unified communications.
• ​​Regulatory alignment​​: Pre-certified for FCC and Energy Star, avoiding compliance hurdles.
• ​​Fiber flexibility​​: SFP uplinks support distances up to 10km for multi-building networks.

​​Key Limitations​​

• ​​No Layer 3 routing​​: Requires an external router for inter-VLAN traffic.
• ​​Single power supply​​: Lack of redundancy risks downtime in 24/7 operations.
• ​​No multi-gig support​​: Limits future readiness for Wi-Fi 6E APs or 5Gbps devices.

​​Practical Evaluation​​

The CBS220-48T-4X-NA is a pragmatic pick for North American businesses needing ​​cost-effective, high-density PoE without enterprise complexity​​. Its ​​simplified Layer 2 management​​ suits teams lacking deep networking expertise, while SFP uplinks add flexibility for growth. However, the lack of redundant power or multi-gig ports makes it a short-term solution for bandwidth-intensive upgrades. If your focus is on deploying reliable, compliant PoE today—and you’re willing to reinvest in five years—this switch hits the mark. Just keep PoE budgeting tight: overloading it could turn a “set-and-forget” deployment into a fire drill.
