D-Link DPS-520 180W PoE Redundant Power Supply (New)

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:

Auto Discovery
Automatically detect PD (powered device) to deliver immediate power

RPS Port Priority
Allows the network administrator to define RPS failover policy

Status Reporting
Monitor status and backup a failed switch via web browser

Plug and Play
Simple installation without complex configurations allows convenient management for network administrators

Over Current Protection
Automatically provides short-circuit protection to prevent equipment damage caused by high currents
