About This Guide

The D-Link DPS-520 is a Redundant Power System (RPS) provides an affordable, 90 Watt, Power over HDBaseT (PoH), rack-mountable, RPS solution. This guide provides step-by-step instructions to setup the RPS and install it to a switch that supports incoming PoH. Please note that the model you have purchased may appear slightly different from those shown in the illustrations. For more detailed information about your product, its components, making connections, and technical specifications, please refer to the User’s Guide included with your product.

Introduction

The DPS-520 provides an effective solution when the internal power supply of a switch in the network fails, which can result in the shutdown of a single switching device or an entire network. With an RPS connected, an integrated detection circuit continuously monitors the switch’s internal power supply. In the event of a power interruption, the RPS is immediately triggered so that the switch and connected devices can continue providing services. This results in a more reliable network infrastructure and protects the network from a single failure of a network device power supply.

Description

The DPS-520 is an RPS unit features four Gigabit Ethernet 90W PoH ports and one Gigabit Ethernet Management port (MGMT). It is designed to conform to the power requirements of the switches being supported. Using PoH, it connects to a PoH-enabled switch using a standard Ethernet UTP/STP cable. A standard, threepronged AC power cable connects the RPS to the main power source.

Rack Installation

The DPS-520 can be installed on a desktop or into a standard switch rack by inserting it into an additional DPS-800. The DPS-800 is a standard-size rack mount (1.25U in height) designed to hold up to two RPS units.

Switch Connection

Only the LAN ports 1 to 4 can supply power to switches. Insert one end of the DC-powered, PoH, Ethernet cable into one of the LAN ports on the DPS-520 and insert the other end into the PoH-capable input port on the switch (usually the MGMT port).

The MGMT port on the DPS-520 cannot supply power to a switch and is usually used for the connection to the management PC.

Power Connection

Connecting AC Power to the RPS Using a standard AC power cable, connect the RPS to the main AC power source. A green LED on the front of the RPS will glow to indicate a successful connection.

Product Specification

RPS Cable Pin Assignment

Any standard Category 5e or higher Ethernet cable can be used to connect the RPS to the switch where the RPS supplies PoH power to the switch. The following illustrates the RJ45 PoH receptacle/connector and pin assignments.

Web User Interface
The Web User Interface (Web UI) provides access to the software features available on the RPS. These features can be accessed on the LAN ports or the MGMT port using any standard web browser, like Microsoft’s Internet Explorer, Mozilla Firefox, Google Chrome, or Safari.

Connecting to the Web UI

To access the Web UI, open a standard web browser, enter the IP address of the RPS into the address bar of the browser, and press the Enter key.

NOTE: The default IP address of the DPS-520 is 10.90.90.90 (subnet mask 255.0.0.0). After successfully connecting to the Web UI, the following is displayed:

System Configuration
The IP Address, Subnet Mask, and Gateway IP address can be configured here. Click the Apply button to apply the changes.

Additional system information is displayed in this section like Hardware Version, Serial Number, Runtime Version, DPS-520 State, Total Power Consumption, Power Budget, Remaining Power Budget, Temperature and the MAC Address of the RPS.

PoE Information
The EEE State and the Link IP address can be configured here. Enter the IP Address of a device, connected to the RPS, and click the Link button to open a new tab in the web browser to initiate an HTTP connection to the specified IP address.

Additional PoE information is displayed in this section like Port number, Link Status, and Power Consumption.

Tools
Click the Apply button, next Factory Default, to reset the software on the RPS back to the factory default configuration.

Firmware Upgrade: To upgrade the firmware, click the Browse button, navigate to the new firmware file, and click the Apply button to upgrade the firmware on the RPS.
Important: The DPS-520 needs to be restarted for the software changes to take effect. To restart the DPS-520, the AC power cord needs to be removed and then re-inserted into the AC power port on the back panel.
