To activate a server connection to the Infoblox Portal by using the Device UI:

1. Connect the following to the appliance:
  1. The power cable that came with the appliance.
  2. An Ethernet cable; use the MGMT port on the front panel of the appliance. You must use the MGMT port to connect to the Infoblox Portal. Once the connection is established, you can use an IPMI port or any other port on the device.  
  
If your network does not have DHCP servers available, the appliance will fall back to the default IP address 192.168.1.2. To configure the physical appliance through an internet browser, ensure that the workstation on which you open the browser has an IP address in the same subnet as that of the appliance. For example, use 192.168.1.2/24 if your network does not have a DHCP server.

3. Open the internet browser on the workstation. If the IP address was allocated via the DHCP server in your network, then enter **[https://192.168.1.2](https://192.168.1.2)**** **or **https://*****<allocated_IP>*** if the IP address was allocated via the DHCP server in your network.  If you cannot access the IP address by using **https://**, try using **http://**.

4. Enter the following credentials for local access:
  1. **Username**: Enter **admin** as the login username of the NIOS-X906 server.
  2. **Password**: Enter the eight-digit serial number of the appliance. Obtain the serial number from the pull‑out tab (on the left side of the rear chassis) or from the Serial console screen.
5. The Device UI appears in the browser. Select the **Network Mode** according to whether you are using the DHCP or a static IP, and then enter information for the IP address.

6. To submit the changes, click **Apply Changes** on the Device UI.

When connecting a hardware appliance to the Infoblox Portal, ensure that you DO NOT enter the join token in the Device UI. Otherwise, the appliance will lose connectivity to the Infoblox Portal when the server certificate expires. Instead, use the serial number of the NIOS-X906 physical server to connect to the Infoblox Portal.

After you have set up the appliance successfully, you will not be able to access the Device UI again unless connection issues occur with the appliance, in which case you can use the Device UI to perform some troubleshooting tasks for the appliance. For more information, see *[Troubleshooting Hosts](https://docs.infoblox.com/space/BloxOneInfrastructure/184681229)*.

If you need to re-configure the appliance, you must first reset it to the factory default. In addition, if you have not configured any NTP server or local DNS resolver, the appliance will use the Ubuntu NTP server ([http://ntp.ubuntu.org](http://ntp.ubuntu.org)  or [ubuntu.pool.ntp.org](http://ubuntu.pool.ntp.org)) and Universal DDI DNS (IP: 52.119.41.100, 52.119.40.100 or 103.80.5.100). Because these services do not communicate via an HTTPS proxy, you must ensure that the NTP port (UDP 123) and the DNS port (TCP/UDP 53) are open on your firewall.
