The DPS-520 provides power supply redundancy and resiliency for Power over Ethernet (PoE). It ensures continuous device activity and offers protection against device power supply failures by providing seamless failover for D-Link switches such as the DGS-1520 series.
- Cost-effective solution that supports up to four switches
- 180W total power budget
- Auto Discovery: automatically discover powered device (PD) to immediately deliver power
- RPS Port Priority: allows network administrator to define RPS failover policy
- Status Reporting: status information can be monitored through any web browser, allowing administrators to backup a failed switch.
High Flexibility and Availability
The DPS-520 PoE Redundant Power Supply system offers stable, reliable safety features and protection to you network. With a 180W power budget and 4 ports with PoE power budget, it can actively back-up four compatible D-Link switches while using PD power connection box, reducing the redundant power cost per device. In the event of a power supply failure, the redundant power supply unit is immediately triggered, allowing the LAN switch and its connected devices to remain operational.
Ease of Use
When connected to compatible D-Link switches, the DPS-520 offers enhanced capabilities to manage power supply redundancy, including:
