SG350-20 Use Case
Unified VoIP and Wireless Campus Edge Switch
In a midsize corporate campus, the SG350-20-8 10/100/1000 PoE switch with 128W power budget and 2 Combo mini-GBIC ports delivers converged voice and wireless services at the network edge. Eight PoE+ ports power IP phones and ceiling-mount Wi-Fi 6 access points without separate injectors. Dual SFP uplinks aggregate traffic into the campus core, ensuring wire-speed performance and VLAN isolation for voice, data and guest segments. Outcome: simplified cabling, guaranteed QoS for voice/Wi-Fi, and scalable fiber uplink for 1 Gbps resiliency.
Retail Branch Networking with PoS and Surveillance
A multi-location retailer deploys the SG350-20-8 10/100/1000 PoE switch with 128W power budget to power point-of-sale terminals, IP cameras and digital signage in each branch store. Eight PoE ports deliver up to 30 W per device for camera arrays and payment kiosks. Two Combo mini-GBIC slots provide fiber uplink redundancy to the regional distribution switch. Outcome: centralized management of VLAN-segmented PoS, video and guest Wi-Fi traffic, reduced hardware footprint and uninterrupted 24/7 store operations.
Branch Office Fiber Uplink and Secure VLAN Segmentation
In a remote office environment, the SG350-20-8 10/100/1000 PoE switch with 128W budget and 2 Combo mini-GBIC ports serves as the primary network aggregation device. Eight PoE+ ports power wireless access points and IP door controllers. Fiber uplinks via mini-GBIC connect to the corporate WAN for encrypted IPSec VPN access. Integrated ACLs and per-VLAN QoS enforce security and bandwidth prioritization between guest, corporate and IoT segments. Outcome: robust fiber connectivity, centralized security policy enforcement and reliable PoE delivery across all edge devices.
