Product Features
Technical Overview
This switch operates at Layer 2 of the OSI model, supporting essential switching functions like VLANs, QoS, and spanning tree protocol for stable network operations. The port configuration includes 48 dedicated 10/100Base-TX Fast Ethernet ports for edge device connectivity, plus two integrated Gigabit Ethernet network ports for higher-speed backbone links. Two shared SFP slots accept mini-GBIC transceivers, allowing fiber optic or copper Gigabit Ethernet uplinks to accommodate diverse cabling infrastructures.
Management is facilitated through a web-based interface or CLI, giving administrators granular control over port settings, traffic prioritization, and security policies. The switch supports standard Ethernet technologies including Fast Ethernet up to 100 Mbps and Gigabit Ethernet up to 1000 Mbps, with compatibility across 10/100Base-TX, 10/100/1000Base-T, and 1000Base-X network standards. Power is supplied via an internal power supply, and the modular design supports expansion without requiring chassis upgrades.
Key Product Advantages
The Cisco SF220-48 combines high port density with enterprise-grade management features at an accessible price point, making it ideal for growing networks that require more control than unmanaged switches provide. Its 48 Fast Ethernet ports allow extensive device connectivity without immediate need for daisy-chaining additional switches, simplifying network topology and reducing potential failure points.
Uplink Flexibility
Dual SFP slots enable fiber or copper Gigabit uplinks, providing options for connecting to core switches or internet gateways over longer distances or in electrically noisy environments.
- Supports 1000Base-X fiber optics
- Copper Gigabit Ethernet via SFP transceivers
- Shared slot design maximizes port utility
Deployment Versatility
The compact 1U height and desktop/rack-mountable design allow installation in space-constrained environments, from small office desks to standard 19-inch server racks.
- 1.73" height fits single rack unit
- Desktop placement for temporary setups
- Rack ears included for permanent installation
Deployment / Use Cases
This switch is well-suited for branch offices, retail locations, or educational environments where multiple devices require reliable wired connectivity with basic traffic management. The 48-port count accommodates classrooms, point-of-sale systems, office workstations, and networked printers simultaneously, while the manageable interface allows segmenting devices into VLANs for security or performance isolation.
In server room applications, the switch can serve as an access layer device, aggregating traffic from end-user devices before passing it upstream via the Gigabit Ethernet ports or SFP uplinks. The refurbished condition makes it particularly attractive for budget-conscious deployments that still demand Cisco's networking pedigree and lifetime warranty coverage. IT managers can deploy it as a core switch in small networks or as a distribution switch in larger hierarchical designs, leveraging its Layer 2 features for improved network control.

FAQ
How many devices can I connect directly to this switch?
The Cisco SF220-48 provides 48 Fast Ethernet ports for direct device connections, allowing you to connect up to 48 PCs, printers, IP phones, or other networked peripherals simultaneously. Additionally, the two integrated Gigabit Ethernet ports and two SFP expansion slots can be used for uplinks to other switches or network infrastructure, further extending connectivity without consuming the primary 48 ports.
What management features does this Layer 2 switch support?
As a Layer 2 manageable switch, it supports VLAN creation for network segmentation, Quality of Service (QoS) for traffic prioritization, spanning tree protocol for loop prevention, and port-based security features. Management can be performed through a web browser interface or command-line interface (CLI), allowing administrators to configure settings, monitor traffic, and implement security policies tailored to their network requirements.
Can I use fiber optic connections with this switch?
Yes, the switch includes two SFP (mini-GBIC) slots that accept fiber optic transceivers, enabling 1000Base-X fiber connections for uplinks. This allows you to connect to other switches or network equipment over longer distances using single-mode or multi-mode fiber cables, providing flexibility in network design and helping overcome copper cable length limitations.
Is this switch suitable for rack mounting?
Absolutely. The Cisco SF220-48 has a 1U height profile of 1.73 inches and includes rack-mount brackets, making it compatible with standard 19-inch server racks.
