Overview of the CBS220-8P-E-2G-IN
The Cisco CBS220-8P-E-2G-IN is a fully managed, Layer 2 switch designed for small businesses and remote offices needing reliable Power over Ethernet (PoE) support in a compact form factor. With 8 PoE+ ports and 2 Gigabit uplinks, this switch balances affordability with enterprise-grade features, making it a practical choice for powering IP devices while ensuring network security and efficiency.
Key Technical Specifications
- Port Configuration: 8 x 10/100 PoE+ ports + 2 x 10/100/1000BASE-T uplinks.
- PoE+ Budget: 130W total power, delivering up to 30W per port for devices like wireless access points, IP cameras, or VoIP phones.
- Layer 2 Features: VLANs, QoS, and static routing for traffic prioritization and network segmentation.
- Security: 802.1X authentication, port security, and DHCP snooping to prevent unauthorized access.
- Energy Efficiency: Complies with IEEE 802.3az (Energy-Efficient Ethernet) to reduce power consumption during low activity.
Who Should Deploy This Switch?
The CBS220-8P-E-2G-IN is ideal for:
- Small offices: Connect workstations, printers, and PoE devices like IP phones or security cameras.
- Retail stores: Power POS systems, digital signage, and surveillance cameras while segmenting guest Wi-Fi traffic.
- Remote workspaces: Provide localized network control with centralized management capabilities.
Addressing Core User Concerns
Q: Can all 8 PoE ports operate at 30W simultaneously?
A: No—the 130W total budget supports ~4–5 high-power devices (e.g., 30W APs) at full load. Mix low-power devices (e.g., 15W phones) to maximize port utilization without exceeding the budget.
Q: Are the uplinks sufficient for high-speed data aggregation?
A: The 2 Gigabit uplinks provide adequate bandwidth for small networks, but for fiber connectivity or higher speeds, consider models with SFP slots (e.g., CBS220-8FP-E-2G).
Q: Is the management interface suitable for non-technical users?
A: Cisco’s web-based GUI simplifies VLAN and QoS setup, while CLI access offers depth for advanced configurations. Cloud management requires third-party integration.
Optimal Use Cases
- Coffee Shops: Power Wi-Fi access points and security cameras while isolating guest traffic from POS systems.
- Home Clinics: Secure patient data networks and connect PoE-enabled medical devices like digital scales or monitors.
- Co-working Spaces: Manage shared printers, VoIP phones, and IoT sensors with traffic prioritization for video conferencing.

Final Perspective
The CBS220-8P-E-2G-IN is a cost-effective solution for small networks prioritizing PoE flexibility and basic managed switching features. While its 130W budget limits high-density 30W deployments, its ease of use and security protocols make it a standout for businesses with modest needs. For IT teams seeking simplicity without sacrificing control, this switch bridges the gap between unmanaged hardware and complex enterprise gear.
