With 48 Gigabit Ethernet ports and 4 dedicated 1G SFP uplink slots, the CBS350-48T-4G is ideal for small to mid-sized businesses, branch offices, and managed service providers looking to expand their infrastructure with confidence.

Key Features:

• Ports: 48 x 10/100/1000 Gigabit Ethernet ports

• Uplinks: 4 x 1G SFP for fiber or long-distance uplink connections

• Switching Capacity: Up to 104 Gbps

• Forwarding Rate: 77.38 Mpps

• Layer 3 Support: Static routing, RIP, VLAN routing

• Management: Web-based GUI, CLI, SNMP, RMON, and Cisco Business Dashboard

• Security: 802.1X, ACLs, DHCP snooping, DoS prevention, storm control

• Energy Efficiency: IEEE 802.3az Energy Efficient Ethernet (EEE)

• Fanless Design: Silent operation in low-power environments (model dependent)

Powerful and Scalable Network Foundation

The CBS350-48T-4G provides the flexibility and bandwidth required to support:

• Office LAN infrastructure

• Wireless access point aggregation

• IP telephony systems

• Surveillance networks

• Cloud-based applications

Its 48 Gigabit ports deliver ample capacity for wired clients, while the 4 SFP uplinks enable high-speed fiber connections to aggregation switches, servers, or the network core—ensuring seamless traffic flow in bandwidth-demanding environments.

Advanced Layer 3 Functionality

Unlike basic unmanaged switches, this model includes Layer 3 static routing, RIP, and inter-VLAN routing, allowing businesses to segment and control traffic more effectively. These features support more complex network topologies and improve performance by limiting broadcast traffic and enabling local routing between VLANs.

Simplified Management and Deployment

The CBS350-48T-4G is designed for easy setup and ongoing operation:

• Web GUI and Cisco Business Dashboard allow intuitive configuration

• Command-Line Interface (CLI) provides granular control for experienced admins

• Remote monitoring via SNMP and RMON

• Auto Voice VLAN and QoS simplify deployment of IP voice and video services

It also supports features like loop detection, auto-negotiation, port mirroring, and firmware upgrades via USB or web interface—streamlining IT operations and reducing setup time.

Enterprise-Grade Security

The switch provides strong integrated security mechanisms:

• IEEE 802.1X port security

• Access Control Lists (ACLs) for traffic filtering

• Denial-of-Service (DoS) protection

• MAC-based port security and storm control

• DHCP snooping and dynamic ARP inspection

These features help prevent unauthorized access, malware spread, and internal threats—essential for maintaining network integrity in today’s connected environments.

Energy-Efficient and Quiet Operation

The CBS350-48T-4G supports Energy Efficient Ethernet (EEE) to reduce power consumption during periods of low activity. Some models also feature fanless designs, making them ideal for deployments in quiet office settings or compact wiring closets.

Conclusion

The Cisco CBS350-48T-4G offers a perfect blend of performance, security, and manageability in a cost-effective package tailored for small and medium businesses. With 48 Gigabit ports, 4 SFP uplinks, robust Layer 3 features, and Cisco’s trusted reliability, it provides a solid network foundation that can scale as your organization grows.

Whether you’re modernizing an existing network or building a new one from the ground up, the CBS350-48T-4G delivers the control and flexibility needed to support your business-critical applications with confidence.
