What Are the ​​Key Features​​ of the CBS220-48T-4G-BR?

The ​​CBS220-48T-4G-BR​​ is a ​​48-port Gigabit Ethernet switch​​ from Cisco’s Small Business series, designed to support high-density deployments. It includes ​​4 Gigabit SFP uplinks​​ for high-speed backbone connectivity and ​​Layer 2 management​​ capabilities, enabling VLANs, QoS, and traffic prioritization. Unlike basic switches, it offers ​​smart managed functionality​​, making it ideal for businesses needing granular control without enterprise complexity.

How Does It Handle ​​High-Power PoE+ Demands​​?

This switch supports ​​Power over Ethernet Plus (PoE+)​​ across ​​24 of its 48 ports​​, delivering up to ​​30W per port​​. This makes it suitable for powering devices like ​​IP cameras, wireless access points, and VoIP phones​​ without external injectors. For businesses with mixed PoE and non-PoE devices, the ​​auto-sensing ports​​ allocate power only where needed, optimizing energy use.

What ​​Security Measures​​ Protect the Network?

Cisco integrates enterprise-grade security into the ​​CBS220-48T-4G-BR​​:

• ​​802.1X authentication​​ ensures only authorized devices connect.
• ​​Port security​​ limits access via MAC address filtering.
• ​​VLAN support​​ isolates sensitive traffic (e.g., finance or HR) from general network traffic.
  These features help businesses meet compliance standards like GDPR or Brazil’s LGPD.

Is It Suitable for ​​Growing Businesses​​?

The ​​CBS220-48T-4G-BR​​ addresses scalability challenges:

• ​​48 Gigabit ports​​ accommodate expanding device counts.
• ​​4 SFP uplinks​​ provide flexibility for fiber or copper uplinks, future-proofing bandwidth needs.
• ​​Smart management​​ simplifies network adjustments as requirements evolve.
  For businesses planning to scale, this switch balances cost and capability effectively.

How Does It Compare to ​​Unmanaged Switches​​?

While unmanaged switches offer plug-and-play simplicity, the ​​CBS220-48T-4G-BR​​ provides critical advantages:

• ​​Traffic prioritization​​ via QoS ensures VoIP and video conferencing remain uninterrupted.
• ​​STP (Spanning Tree Protocol)​​ prevents network loops, enhancing reliability.
• ​​Energy-efficient design​​ reduces power consumption by up to 30% compared to older models.

Final Thoughts

Having deployed similar switches in mid-sized retail environments, the ​​CBS220-48T-4G-BR​​ stands out for its ​​PoE+ capacity​​ and ​​ease of management​​. While the 24 PoE ports may limit larger deployments, it’s a cost-effective solution for businesses needing to power clusters of devices while maintaining network control. For Brazilian enterprises or those with similar compliance needs, its security features add significant value.
