Optional Power Supply Modules

A secondary PSU module bay is available for reserving a hot-swappable, backup PSU or for increasing the DC output power to 300W. Two PSU models are available:

AC/DC 54V, 150W PSU Model EP-54V-150W-AC DC/DC 54V, 150W PSU Model EP-54V-150W-DC

Hardware Overview

Management Port

10/100 Ethernet port for accessing the EdgePower Configuration Interface.


Primary PSU module bay supports a 150W PSU module. Factory default is On, and is configurable through the EdgePower Configuration Interface.


Secondary PSU module bay supports an optional 150W PSU module for increasing power output, or configured Off to house a spare PSU module. Factory default is On, and is configurable through the EdgePower Configuration Interface.

DC Out

    Note: Connecting to the Management Port is only necessary for accessing the configuration interface to configure PSU 2 or to monitor power.

Installing a Ground Wire

We recommend installing a ground wire for added ESD protection and as a safety precaution.

Note: For guidelines about grounding and lightning protection, follow your local electrical regulatory codes.

Installing a Secondary PSU Module (Optional)

Accessing the Configuration Interface (Optional)

Access the EdgePower Configuration Interface to monitor status and power consumption, or to configure the PSU modules and network settings.

Configuration is only necessary if you have an optional PSU module installed in the PSU 2 bay and need to deactivate it. By default, PSU 2 is on and configured to provide additional power output.

Note: The EdgePower is set to DHCP by default with a fallback IP address of

  1. Connect an Ethernet cable from your host system to the Management Port.
  2. Configure the Ethernet adapter on your host system with a static IP address on the 192.168.1.x subnet.
  3. Launch your web browser. Type in the address field. Press enter (PC) or return (Mac).

  4. Enter ubnt in the Username and Password fields. Click Login.
  5. To change the PSU module priority, select the appropriate PSU Priority on the Power screen, and click Save Changes.
  6. The PSU LED will light amber and the LED on PSU 2 will turn off, indicating that only PSU 1 is on and operational. Total power output is up to 150W.
