Network Connection and Discovery

In order to connect to and interact with a Rubix Compute controller it must be connected to a network via Ethernet cable.  The best way to connect to the Rubix Compute is via a router.  Alternatively, the Rubix Compute Controller can be connected directly to a PC via ethernet.

Network Architecture

To add a Nube-iO Rubix Compute Gateway Controller to a network, an ethernet cable must be connected to one of the Ethernet ports on the controller; generally this will be using the ETH-2 port.  The other end of the Ethernet cable should be connected (directly or indirectly) to the Network Router.  The cable architecture back to the Network Router can be via a number of Network Switches.  Below are examples of valid Ethernet networking architectures.

Default Network Configuration

When a Rubix Compute Controller is reset to factory defaults the 2 x Ethernet ports will be configured as follows:

Note: The 2 Ethernet ports on the Nube-iO Rubix Compute Gateway Controller are for connecting to 2 separate networks.  They cannot be used to extend a single network.

Connecting Via Router (recommended)

When connecting to the Rubix Compute controller via a network router, ethernet port  ETH-2 should be used (at default network settings).  Once connected via an ethernet cable, find the automatically assigned IP Address by using the router’s admin user interface; or by running an IP/Port Scanning Software (Port Scanner - Wikipedia). Recommended IP/Port scanners include Angry IP Scanner or  Advanced IP Scanner.

When you think you have found the correct IP Address, try running a PING check on that IP Address; If successful, unplug the Rubix Compute controller, and re-run a PING check to see that the PING check now fails.  Then reconnect your Rubix Compute controller.

Direct Connection to PC

When connecting a Rubix Compute controller directly to a PC via an ethernet cable,  ethernet port ETH-1 should be used (at default network settings).  Ensure that the PC has self-assigned a static IP Address in the same subnet range as the Rubix Compute (default 192.168.15.xxx)

Note: There cannot be identical IP Addresses on the same network.

Once connected, and the PC IP Address is configured, try running a PING check on the Rubix Compute IP Address (default: 192.168.15.10).

This method is not recommended as it is quite difficult to provide the Rubix Compute Controller an internet connection when connected directly to a PC.  It is recommended to connect via a network router.
