Overview of the CBS220-48P-4G-UK Switch

The ​​CBS220-48P-4G-UK​​ is a Cisco Small Business 220 Series switch designed for growing enterprises requiring reliable Layer 2 management and Power over Ethernet (PoE) support. With ​​48 PoE+ ports​​ and ​​4 Gigabit uplinks​​, it balances scalability, energy efficiency, and ease of deployment for networks prioritizing voice, video, and IoT device integration.

Key Technical Specifications

• ​​Port Configuration​​: 48 x 10/100/1000 PoE+ ports, 4 x 1G SFP uplinks.
• ​​PoE Budget​​: 370W total, supporting devices like IP cameras, VoIP phones, and wireless access points.
• ​​Layer 2 Features​​: VLAN, QoS, IGMP snooping, and static routing.
• ​​Management​​: Web-based GUI or Cisco Business Dashboard for centralized control.

Addressing Core User Concerns

Is the CBS220-48P-4G-UK Suitable for High-Density PoE Deployments?

The switch’s ​​370W PoE budget​​ supports up to 30W per port (IEEE 802.3at), making it ideal for medium-sized offices deploying 20–30 PoE devices. However, users must calculate total power requirements for connected devices to avoid overloading the system.

How Does It Compare to Layer 3 Switches?

Unlike Layer 3 switches, the CBS220-48P-4G-UK focuses on ​​cost-effective Layer 2 segmentation​​ and traffic prioritization. It lacks dynamic routing protocols (e.g., OSPF, BGP) but compensates with robust QoS policies for VoIP and video traffic optimization.

Can It Integrate with Existing Cisco Networks?

Yes. The switch supports ​​Cisco Plug-and-Play​​, simplifying integration with other Cisco routers or wireless controllers. For advanced security, pair it with Cisco firewalls to create a unified threat management framework.
