## Pre-installation <a href="#id-inst-alla-tio-n-pre-installation" id="id-inst-alla-tio-n-pre-installation"></a>

Requirements for the deployment:

* A virtualization server controlled by a hypervisor compatible with **NEXT**.
* OVA image (Open Virtualization Format) with the latest version of monitoring system, downloaded from the official FTP server.

## Installation <a href="#id-inst-alla-tio-n-installation" id="id-inst-alla-tio-n-installation"></a>

{% hint style="warning" %}
**NOTE**

In this installation example, the VMware ESXi hypervisor is used. For deploying to a different hypervisor, proceed according to the user guide of the product.
{% endhint %}

### Step 1 - import the OVA image <a href="#id-inst-alla-tio-n-step1-importtheovaimage" id="id-inst-alla-tio-n-step1-importtheovaimage"></a>

* Launch vSphere Client and connect to a hypervisor.
* Run the image import wizard "**File → Deploy OVF Template**".

In the first step of the wizard click on the "Browse" button and and specify the path to the **NEXT** image file. Click on the "Next" button to proceed to the following step.

At the next step specify the formatting requirements for the space allocated in the repository. Keep the default settings and click "Next" to continue.

<figure><img src="https://2734851754-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FnG7V17JtC1mMJOmveKc6%2Fuploads%2FevtyREHr5Vc6SYwR3Drx%2Fimage.png?alt=media&#x26;token=33cd5881-59a9-4e01-a1a1-3e2902938751" alt=""><figcaption></figcaption></figure>

Let's configure the network connection of the virtual machine to the local network. It depends on the hypervisor's configuration and on the local network topology. The selection of the network connection is determined by the following requirements:

* the monitoring system must have network access to the wireless devices;
* the wireless network administrators must have access to the web interface of the monitoring system;
* to make updates, the monitoring system must have access to the update server located in the Internet;
* for the correct functioning of the notification subsystem, the monitoring system must have network access to the corresponding email server.

Click "Next" to continue.

<figure><img src="https://2734851754-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FnG7V17JtC1mMJOmveKc6%2Fuploads%2FejHrOWokGbA0qe12KqAx%2Fimage.png?alt=media&#x26;token=83e83c29-ba21-4b89-a5d9-2129d1fc0432" alt=""><figcaption></figcaption></figure>

In the final step, the summary information about the parameters of the newly created virtual machine is displayed. Check it and return to the appropriate steps to make adjustments, if necessary.

Set the "Power on after deployment" flag in order to automatically start the virtual machine after it is created.

If all the parameters are correct, click the "Finish" button to complete the image import and create a virtual machine with the **NEXT** monitoring system.

<figure><img src="https://2734851754-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FnG7V17JtC1mMJOmveKc6%2Fuploads%2FIxKdcdDDn7Fwqvy80MFe%2Fimage.png?alt=media&#x26;token=757a177f-879c-4e77-9b55-84653aa2ced2" alt=""><figcaption></figcaption></figure>

Now the virtual machine is created. Run it manually if you have not chosen to start the virtual machine automatically in the previous step.

{% hint style="warning" %}
**NOTE**

To ensure **NEXT** work correctly, make sure that EFI support is enabled on the virtual machine. Open the virtual machine's settings by clicking "**Edit settings**" button, proceed to "VM Options" **→** "VMware Tools", if necessary in the "Firmware" subsection select the "**UEFI**" option (virtual machine should be turned off).
{% endhint %}

### Step 2 - NEXT pre-configuration <a href="#id-inst-alla-tio-n-step2-nextpre-configuration" id="id-inst-alla-tio-n-step2-nextpre-configuration"></a>

{% hint style="warning" %}
**NOTE**

In the first beta version, only the network settings are available for configuration. In the future, the list of adjustable parameters will expand.
{% endhint %}

Open the virtual machine's console. After **NEXT** loads, the service mode is launched, in which the basic parameter configuration, necessary to start the monitoring system, is available.

The network connection settings are the most important. By default, **NEXT** attempts to obtain the network settings via DHCP. To set static values, disable DHCP and manually specify the following parameter values:

* IP address and network mask of the monitoring system's network interface;
* Default gateway IP address;
* DNS server's IP address.

Click on the "Apply" button after setting all the parameters.

<figure><img src="https://2734851754-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FnG7V17JtC1mMJOmveKc6%2Fuploads%2FBKPHB1eFmM2zdCDQLLq1%2Fimage.png?alt=media&#x26;token=b7d4dfa5-d786-4a5a-9db2-c2acb52a72ca" alt=""><figcaption></figcaption></figure>

The preliminary configuration is completed, now you can connect to **NEXT** monitoring system's web interface where you will be met by installation wizard.

## Time settings <a href="#id-inst-alla-tio-n-timesettings" id="id-inst-alla-tio-n-timesettings"></a>
