DPS-500DC-CN Use Case
Enterprise Data Center High-Availability Switching
In a global financial services data center deploying DGS-3630-40T-CN leaf switches, the DPS-500DC-CN-D-Link DC redundant power supply provides dual hot-swappable DC inputs for uninterrupted operation. By integrating with existing –48 VDC busbars, the DPS-500DC-CN eliminates single-points-of-failure and supports non-stop packet forwarding during maintenance or utility fluctuations. The outcome: 99.999% network uptime, reduced mean time to repair (MTTR), and guaranteed SLA compliance for latency-sensitive trading applications.
Telecommunications Edge Site Power Resilience
At a regional telecom PoP using DGS-3630-40S-CN SFP switches, the DPS-500DC-CN-D-Link DC redundant power supply ensures continuous power from two independent –48 VDC rectifiers. In the event of a rectifier fault, the DPS-500DC-CN instantly transfers load without rebooting critical voice and data circuits. Benefit: zero service interruptions, automated failover, and optimized network reliability for mobile backhaul and broadband aggregation.
Industrial Automation Control Network Continuity
In a manufacturing plant’s automated control room, DGS-3630-40T-CN switches feed SCADA and PLC systems. The DPS-500DC-CN-D-Link DC redundant power supply delivers resilient –48 VDC power across production lines, allowing hot-swap maintenance while preserving VLAN segmentation and real-time monitoring. Result: uninterrupted process control, enhanced safety compliance, and minimized production downtime, driving higher OEE (Overall Equipment Effectiveness).
