PoE Redundant Power Supply
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:
Automatically detect PD (powered device) to deliver immediate power
Allows the network administrator to define RPS failover policy
Monitor status and backup a failed switch via web browser
Simple installation without complex configurations allows convenient management for network administrators
Automatically provides short-circuit protection to prevent equipment damage caused by high currents
Offering a 90W power budget per port and a total of 180W for reliable backup power
The DPS-520 can be installed on a desktop or onto a standard switch rack by inserting it into an optional DPS-800. The DPS-800 is a standard-size rack mount designed to hold up to two DPS-520 RPS units.
Any standard Category 5e or higher Ethernet cable can be used to connect the RPS to the switch, allowing the RPS to supply PoH power to the switch with up to 100m connection distance.
