Use Cases & Applications

Multi-Floor Office Buildings: The CBS350-48P-4G serves as an ideal distribution switch for offices spanning multiple floors. Connect it to a core switch via fiber uplinks while powering all desk phones, access points, and security cameras on a single floor. The Layer 3 routing capability enables you to create separate subnets per floor without additional routing hardware.

Hotels and Hospitality: Deploy the switch to power guest room access points, corridor cameras, and digital signage throughout an entire hotel floor. Additionally, the Voice VLAN feature automatically prioritizes front desk phone traffic while guest WiFi traffic remains on a separate, lower-priority network segment.

Healthcare Clinics: Medical facilities benefit from the CBS350-48P-4G’s ability to segment patient WiFi, staff networks, and medical device traffic into isolated VLANs. The 802.1X authentication ensures only authorized devices connect to sensitive patient data systems.

Education Campuses: Schools can connect classrooms, administrative offices, and common areas through this switch while maintaining network separation. For instance, student devices access restricted networks while teacher workstations and administrative systems operate on secure VLANs with full access to school resources.

Retail Chain Stores: Support point-of-sale systems, IP security cameras, wireless access points, and digital menu boards from a central switch location. The QoS features ensure payment processing remains fast even during peak shopping hours when customer WiFi usage is high.

Why Choose the CBS350-48P-4G

The CBS350-48P-4G bridges the gap between basic plug-and-play switches and complex enterprise equipment. Unlike unmanaged switches, it offers granular control over network traffic and security. However, it maintains simpler configuration options compared to Catalyst enterprise switches, making it accessible for small IT teams.

The 375W PoE budget supports approximately 12 high-power devices at maximum draw or up to 48 standard IP phones simultaneously. This makes the switch particularly cost-effective for businesses deploying modern WiFi 6 access points that require 25-30W each.
