Nucleus Web Administration Interface

Nucleus Web Administration Interface

Connecting to the Web Administration Interface

You can use a web browser to perform operations like configuring settings, updating firmware, formatting internal storage, and resetting to factory settings. To use Roon to help you load up the Nucleus Web Administrative Interface, visit the Connecting to Nucleus guide. You can access the Web Administration Interface by going to Settings > Setup > Find Roon OS as seen below.

To get to the Nucleus Web Administration Interface, you need to click on “Find", which will show you a screen like this:

Your Nucleus should be automatically found and listed. Click on its IP address as shown and the Nucleus Web Administration Interface will open in a web browser.

Using the Web Administration Interface


The following functions can be performed from the Web Administration Interface:
  1. Reboot or power off - At the top right is a red button, which can be used to reboot or power off the Nucleus. 
  2. Reinstall RoonOS and RoonServer - Next to the Operating System section is a Reinstall button that installs the latest firmware available for Nucleus, even if you are up to date. This operation can take several minutes depending on your internet connection. This button will always reinstall the latest firmware, even if you are already running the latest.
    1. Reinstalling the software will not affect your settings or your Roon Database. 
  3. Stop and Restart RoonServer - Next to the Roon Server Software section is a button/drop-down that lets you stop/start or restart Roon Server. Stopping Roon Server can be useful before doing a large import. 
  4. Reset all Settings / Databases - It is possible to reset all Nucleus settings, Roon settings, and your Roon database back to "factory defaults". To do this, click Reset next to the Roon Database & Settings section.
    1. This will not make any changes to your internal storage
  5.  Format internal storage - If you have a hard disk drive (HDD) or solid-state drive (SSD) installed in the Nucleus, it must be formatted by Roon OS before it can be used. More information on internal storage can be found here.
  6. Setting a static IP address - Like most networked devices, Nucleus defaults to DHCP for the configuration of its network interface. Using a static IP for Nucleus is often not required and not recommended.
    1. To configure the interface manually, change the IP Address Setup to Static IP, then manually enter IP Address, Netmask, Gateway, and DNS Server.
    2. Note: Incorrect static IP settings could render your Nucleus unreachable on your network. A thorough understanding of networking principles and familiarity with the host network is strongly recommended if you intend to configure your network interface manually. 
    3. If you accidentally enter an incorrect static IP and your machine is left unreachable, you can use a second network interface to help get out of this situation (because it will be configured by default to use DHCP). 
  7. Configuring a second network interface - If you use a USB network adapter with Nucleus, it will populate itself with a second network interface. This second interface will appear as a new tab under the Networking section and can be configured the same way as the onboard gigabit ethernet port. 

Other easy ways to access the Nucleus Web Interface can also be accessed by:

  1. Typing in the IP Address of the RoonOS Device in a Web Browser
  2. Typing the hostname of the device, for example: http://rock , http://nucleus , http://nucleusplus , http://nucleustitan or http://nucleusone  
  3. Typing the .local suffix for the device, for example: http://rock.local , http://nucleus.local ,  http://nucleusplus.local , http://nucleustitan.local , or http://nucleusone.local
