# Software Installation Guide Dell

## Installing flexAIserver

This guide describes two methods for installing the **flexAIserver** software on a supported Dell PowerEdge server:

- **Method A:** Installation from a bootable USB drive
- **Method B:** Remote installation using Dell iDRAC Virtual Console and Virtual Media

Both methods use the same flexAIserver installation image. Once the installer has started, the remaining installation procedure is identical.

### Prerequisites

Before starting the installation, make sure the following are available:

- flexAIserver ISO image. The ISO may be supplied inside a ZIP archive and must be extracted before use.
- Access to the Dell PowerEdge server.

For **Method A – USB**, you also need:

- A USB flash drive
- Physical access to the server
- A keyboard and, if required, a local display

For **Method B – iDRAC**, you need:

- Access to the Dell iDRAC interface
- Permission to use **Virtual Console** and **Virtual Media**

<p class="callout warning">**Important -** Installing flexAIserver erases the selected target disk. Make sure that the correct server and target disk have been selected before continuing.</p>

## Method A – USB Drive

### 1. Create a Bootable USB Drive

Use a suitable image-writing tool such as **balenaEtcher** to write the flexAIserver ISO image to a USB flash drive:

<p class="callout warning">**Important -** Writing the ISO image erases all existing data on the USB drive.</p>

When the USB drive is ready:

1. Insert it into a USB port on the server.
2. Connect a keyboard.
3. Power on or restart the server.

### 2. Open the Boot Manager

During server startup, press **F11** to open the Dell Boot Manager.

## Method B – Dell iDRAC Virtual Media

### 1. Map the ISO as Virtual Media

Open the Dell **iDRAC Virtual Console**.

In the Virtual Console, open **Virtual Media** and map the flexAIserver ISO image as a virtual CD/DVD.

<span style="color:#4f81bd;"><span style="font-size:small;">**iDRAC – flexAIserver ISO mapped as Virtual CD/DVD. iDRAC installation only.**</span></span>

### 2. Restart the Server

From iDRAC, select **Power &gt; Reset System (warm boot)** to restart the server and make the virtual installation media available during boot.

<span style="color:#4f81bd;"><span style="font-size:small;">**iDRAC – restart the server using Reset System (warm boot). iDRAC installation only.**</span></span>

### 3. Boot from the Virtual Optical Drive

During startup, open the **Boot Manager**, select **One-shot UEFI Boot Menu**, and then select **Virtual Optical Drive**.

### 2. Set the Host Name

When prompted, enter the host name to be used by the flexAIserver.

For a Jünger Audio pre-configured system, the host name can follow the device serial number, for example:

`flexAIserver-00119`

Alternatively, use a suitable host name according to the naming conventions of your network environment.

### 3. Select the Target Disk

Select the internal system disk on which flexAIserver should be installed.

On Dell PowerEdge systems with a PERC RAID controller, the internal storage may appear with a name such as **DELL PERC**.

For USB installations, make sure that you do **not** select the USB installation drive.

<span style="color:#4f81bd;"><span style="font-size:small;">**Select the internal system disk. Do not select the USB installation drive. Applies to both installation methods.**</span></span>

<p class="callout danger">**Important -** All existing data on the selected target disk will be erased during installation. Verify the selected disk carefully before continuing.</p>

### 4. Complete the Installation

Allow the installer to complete the installation process.

<span style="color:#4f81bd;"><span style="font-size:small;">**Installation complete. Applies to both installation methods.**</span></span>

Before rebooting:

- **USB installation:** Remove the USB installation drive.
- **iDRAC installation:** Unmap or disconnect the virtual installation media.

Restart the server and allow it to boot from the newly installed system disk.

Continue with the **Initial Setup** procedure to complete the flexAIserver configuration.
