CBS220-48T-4G-NA – Cisco Business 220 48-Port Gigabit Smart Switch with 4 Gigabit SFP Uplinks

BRAND NEW WITH FULL CISCO WARRANTY!!!

overview

The CBS220-48T-4G-NA Cisco Business 220 Series 48-Port Gigabit Smart Switch with 4 Gigabit SFP Uplinks is designed for small and medium-sized businesses that need dependable wired connectivity, practical network management, and room for network expansion. It provides 48 Gigabit Ethernet ports for connecting workstations, printers, servers, and other network devices, alongside four Gigabit SFP uplinks for fiber-optic connectivity to compatible network infrastructure.

With a 104 Gbps switching capacity and forwarding performance of up to 74.38 million packets per second, the CBS220-48T-4G-NA supports business workloads that require consistent Gigabit Ethernet performance. Its smart-switch functionality includes VLAN configuration, Quality of Service (QoS), link aggregation, access control lists, and spanning-tree protocols to help administrators segment traffic and improve network reliability.

Designed for rack-mounted deployment, this Cisco Business 220 switch combines a compact 1U chassis with an internal power supply and web-based management capabilities. It is a practical option for office wiring closets, departmental networks, retail locations, and small-business infrastructure that requires more control than an unmanaged switch without the complexity of a larger enterprise switching platform.

FAQs – CBS220-48T-4G-NA

1. Can the CBS220-48T-4G-NA support a growing office network?

Yes. It provides 48 Gigabit Ethernet access ports and four Gigabit SFP uplinks, making it suitable for connecting many wired endpoints and linking the switch to compatible upstream network equipment.

2. Is the CBS220-48T-4G-NA a managed or unmanaged switch?

It is a smart switch. It provides configuration and monitoring capabilities, including VLANs, QoS, link aggregation, and access control lists, without the complexity of a full enterprise Layer 3 switching platform.

3. Does this switch support Power over Ethernet (PoE)?

No. The CBS220-48T-4G-NA is a non-PoE model. Devices such as access points and IP phones that require PoE need separate compatible power injectors or a PoE-capable switch.

4. Can the switch connect to fiber-optic networks?

Yes. It includes four Gigabit SFP uplink ports. Compatible SFP transceivers and fiber cabling must be selected according to the required fiber type, distance, and network equipment.

5. Does the CBS220-48T-4G-NA support redundant power supplies?

The model has an internal power supply. A second, built-in redundant power supply is not specified, so deployments requiring power redundancy should use an appropriate external power-resilience design.

6. Is this switch suitable for a server room or network rack?

Yes. Its 1U rack-mountable form factor and 48 Gigabit Ethernet ports make it suitable for office wiring closets, server rooms, and small-business network racks. Ensure the installation provides suitable ventilation and access to AC power.
