SG350-28SFP Use Case
Secure VLAN Segmentation for Mid-Size Law Firm Network
In a 150-user law firm, the SG350-28SFP-24 10/100/1000 switch deploys dedicated VLANs for attorneys, paralegals and guest Wi-Fi, while two Gigabit copper/SFP combo and two SFP uplinks connect to the data center firewall. This setup isolates sensitive case files, enforces role-based access control and minimizes broadcast domains. Outcome: enhanced network security, simplified compliance and deterministically low latency between client workstations and file servers.
Campus Fiber Backbone Redundancy in University IT Infrastructure
A university IT team uses the SG350-28SFP-24 to aggregate classroom and research lab traffic, leveraging its two dedicated SFP ports and two copper/SFP combos for redundant fiber rings between buildings. Rapid Spanning Tree Protocol (RSTP) ensures sub-second failover during fiber cuts. Outcome: uninterrupted gigabit connectivity across campus, optimized bandwidth utilization and streamlined network management through the web-based GUI.
High-Performance Virtualization Edge in SMB Data Center
An SMB data center integrates the SG350-28SFP-24 at the top-of-rack to connect eight ESXi hosts and shared storage arrays using 10/100/1000 copper ports. Dual SFP uplinks tie into a core switch cluster for server-to-server east-west traffic. Quality of Service (QoS) prioritizes VM replication and VoIP. Outcome: consistently high throughput, sub-millisecond latency for virtualization workloads and centralized traffic analytics for capacity planning.
