Server Installation
Prerequisites:
- Access to a Site in the XS4 Face Console, with permissions to add servers.
- A machine which meets the XS4 Face Server System Requirements.
To configure a machine as an XS4 Face Server, navigate to the Servers page in the XS4 Face Console and click Add Server.
This will open the installation wizard.
Express installation
The express installation is divided into two stages: Stage 1 sets up and configures the server, while Stage 2 is site-specific and installs the XS4 Face Software.
Select Express.
Create a name for the server, and click Continue.
Boot the installation software on the target machine:
- If using a physical machine, insert a Server Installation USB into the target machine and boot the machine from that USB drive. You may need to adjust the BIOS/UEFI settings to prioritize booting from USB, refer to machine manufacturer documentation for instructions.
- If using a virtual machine, refer to the Server Virtualisation guide to set up a virtual machine that boots from the XS4 Face Server Installer ISO.
Wait for the latest installation software to download, once downloaded it will start automatically.
When the installation software has started, select your preferred language, and click Continue.
Select the disk from the drop-down menu to install the XS4 Face Server software on, and click Continue.
The installer will perform system checks to ensure the machine meets the minimum requirements. If the checks pass, click Continue to proceed. If any checks fail, address the issues and rerun the checks.
The installer is then ready to begin installation of stage 1. Remove the installation media and click Install to start.
Once stage 1 of installation has completed, stage 2 will download automatically and display the next steps. Select the timezone and click Continue.
The installer will perform network checks to ensure the machine can access the necessary connections. If the checks pass, click Continue to proceed. If any checks fail, address the issues and rerun the checks.
Use the network information displayed to reserve the IP address for the server in your router or DHCP server, and click Continue.
On the Server Pairing screen, make a note of the pairing code displayed.
Return to the XS4 Face Console, enter the pairing code, and click Continue.
When the pairing is successful, the installer on the target machine will proceed to the next step: Download which will automatically begin downloading the XS4 Face Software.
When the installation is complete, you can close the wizard in the XS4 Face Console by clicking Continue.
Advanced installation
Run an installation script on a machine running Ubuntu Server 24.04 LTS (minimal) to install the XS4 Face Server software.
Follow the Ubuntu Server 24.04 LTS installation guide to install the required operating system on the target machine.
Select Advanced.
Reserve an IP address for the server in your router or DHCP server and enter this address into the IP Address field, then click Continue.
On the target machine, open a terminal and run the installation script provided. Answer the prompts as they appear and wait for the installation to complete.
When the installation is complete, you can close the wizard in the XS4 Face Console by clicking Continue.
Azure installation
Beta
Deploy an XS4 Face Server into your own Microsoft Azure subscription, using a confidential or trusted launch virtual machine. Salto technical support must enable this option for the site. If it isn't enabled, the Azure option shows that the feature isn't available.
Prerequisites:
- An Azure subscription with a resource group, a virtual network and a subnet for the XS4 Face Server.
- Enough quota in your Azure region for the virtual machine size. For the supported sizes, see Azure virtual machines.
- An SSH key pair for the administrator account of the virtual machine.
- The Azure CLI, for example in Azure Cloud Shell.
Select Azure.
Enter a name for the server and the private IP address that the virtual machine will use in your subnet, then click Continue.
Select the Azure VM Type: Confidential Compute or Trusted Launch.
Enter the details of your Azure environment: Azure VM Size, Azure Subscription ID, Azure Resource Group, Azure Virtual Network Name, Azure Subnet Name, Azure VM Name, Azure SSH Admin Username, Azure SSH Public Key and, optionally, Azure Tags. The XS4 Face Console builds the Azure Deployment Command from these details.
Click Copy Command, then run the command with the Azure CLI. The command uses
az deployment group what-if, which shows the changes it would make to your Azure environment without making them.Review the changes. When you're ready to deploy, replace
what-ifwithcreatein the command and run it again.Wait for the XS4 Face Server to start and connect to the XS4 Face Console, then click Continue to close the wizard.
