# Front and Rear Panel ### Front Panel [](https://docs.junger.audio/uploads/images/gallery/2026-09/scaled-1680-/Okq3EHgoW6f0r2vd-aixpressor-frontdropshadow-2019-10-2000px-png.png) The AIXpressor front panel provides direct access to the following connections and controls: - **USB:** USB 3.0 Type A connector for removable storage and other supported USB devices - **Headphones:** 6.3 mm (1/4") stereo headphone output - **Display:** 1440 × 240 TFT touch display for local operation and status information ### Rear Panel [](https://docs.junger.audio/uploads/images/gallery/2026-09/scaled-1680-/6gnjfsbfNOAkjKpN-aixpressor-rear.jpeg) The rear panel provides power, network, synchronization, audio I/O, and expansion connections. #### Power - **Redundant Power Supplies:** Two auto-ranging mains inputs with individual power switches - The two power supplies operate redundantly and share the system load during normal operation. For maximum redundancy, connect the two power supplies to independent mains circuits as described in the **Power** section. #### Network - **Ethernet:** Four Gigabit Ethernet RJ45 ports for control, management, and Audio over IP - **LAN 3 and LAN 4** are internally connected through an integrated network switch. The assignment of the network ports depends on the system and AoIP configuration. #### USB and Service - **USB Type A:** One USB 3.0 Type A connector - **USB Type B:** One USB 2.0 Type B connector; currently unused - **Status LED:** Provides a general indication of the system state. Green indicates normal operation. - **Init / Reset:** Service function intended for use in consultation with Jünger Audio support. #### MADI / tieLight Two SFP cages provide the built-in **MADI / tieLight** interfaces. The operating mode of each interface is selected in the software. MADI and tieLight require different SFP module types.Depending on the installed module, MADI connections can be provided as optical single-mode, optical multi-mode, or **coaxial BNC** interfaces.
#### External Synchronization A 75 Ω BNC connector provides the external synchronization input. Supported synchronization formats include: - Word Clock - AES3 / AES11 - Black Burst - Tri-Level Sync #### AES3 I/O The built-in AES3 interface uses a 25-pin D-Sub female connector. It can be configured as: - **8 AES3 inputs / 8 AES3 outputs**, or - **4 AES3 inputs / 12 AES3 outputs** AES3 is also commonly referred to as **AES/EBU**. #### Analog I/O The built-in analog interfaces use two 25-pin D-Sub female connectors: - One connector provides **8 balanced analog outputs**. - The second connector provides **8 balanced analog inputs**, or can be configured as **4 balanced inputs / 4 balanced outputs**. This allows the complete analog interface to operate as either: - **8 inputs / 8 outputs**, or - **4 inputs / 12 outputs** #### Expansion Slots AIXpressor provides four interface expansion slots, **IF 1 – IF 4**, for optional interface boards. Each slot supports up to **64 bidirectional audio channels**, depending on the installed interface module. Available expansion modules include interfaces for applications such as SDI, MADI, Dante, AES3, analog audio, and microphone inputs. # Network Connections #### General Network Considerations By default, **DHCP is enabled on all AIXpressor network interfaces**. When connected to a network with an active DHCP server, each interface automatically obtains an IP configuration. The IP address assigned to **LAN 1 CTRL** is shown on the front-panel display. If no DHCP server is available, a static IPv4 address can be configured for LAN 1 CTRL from the front panel to establish an initial network connection. AIXpressor also supports **Zero Configuration Networking (mDNS/Bonjour)** and can therefore be reached by its `.local` host name on compatible networks.**Note -** The network settings available from the front panel apply to \\\*\\\*LAN 1 CTRL\\\*\\\* only.
**Note -** When integrating the AIXpressor into a managed network, coordinate the required IP addressing and network settings with the network administrator.
#### Accessing the Web Interface To connect using the IP address shown on the front panel, enter the address in a web browser: `https://**Critical information - Please read carefully.**
## Safety Information ### Electrical Safety - **Safety Classification:** AIXpressor is a Class I grounded product and must be operated with a protective earth connection. - **Mains Connection:** Connect the unit only to properly grounded mains outlets. The power cords must remain accessible so that the unit can be disconnected from mains power when required. - **Power Switches:** Each power supply has its own On/Off switch located next to the corresponding mains inlet on the rear panel. The switch positions are marked **I** for On and **O** for Off. - **Redundant Power Supplies:** AIXpressor is equipped with two power supplies and therefore uses two mains power cords. Both connections must be disconnected to completely remove mains power from the unit. - **Protection from Water:** Do not expose the unit to dripping or splashing water. Do not place containers filled with liquid on or directly above the unit. ### Service Safety Service work should only be carried out by qualified personnel. Before opening or servicing the unit: 1. Switch off both power supplies. 2. Disconnect both mains power cords. 3. Make sure that the power cords cannot be reconnected accidentally while service work is in progress. Do not perform service work on the unit while it is connected to mains power unless the procedure specifically requires this and is carried out by suitably qualified personnel. ### Installation and Operation - Install AIXpressor on a stable surface or securely mount it in a standard **19-inch equipment rack**. - When installed in a rack, make sure that the unit is adequately supported and securely fastened. - AIXpressor is actively cooled. Viewed from the front, cooling air enters on the **left-hand side** and exits on the **right-hand side**. Keep these ventilation openings clear and provide sufficient airflow around the unit. - Do not operate the unit with covers or panels removed. - Use only mains power cords that are suitable for the product and approved for use in the country or region of installation. - If the unit, power cords, connectors, or other components appear damaged, disconnect the unit from mains power and have it inspected by qualified service personnel before further use. ### Internal Battery AIXpressor contains an internal lithium battery.The battery must only be replaced with the specified type and by qualified service personnel. Using an incorrect battery type or installing it incorrectly may present a risk of fire or explosion.

If flexAI is installed on different server hardware, refer to the manufacturer's documentation for model-specific installation, cooling, power, and safety requirements.
The pre-configured **flexAIserver** is a **1RU, 19-inch rack-mount server** intended for installation in a standard equipment rack. Install the server using the appropriate rack-mounting hardware and make sure that it is adequately supported. The server is actively cooled. Keep all ventilation openings clear and ensure sufficient airflow through the rack. Additional spacing above or below the server is normally not required unless specified by the server manufacturer or required by the cooling concept of the installation. ### Power The pre-configured flexAIserver is equipped with redundant power supplies. Connect both power supplies for redundant operation. If one power supply fails, the remaining supply can continue to power the server. For installations requiring high availability, connect the two power supplies to **independent mains circuits** whenever possible. Ideally, the circuits should also be backed by separate UPS feeds or other suitable backup power arrangements. This provides protection not only against a power supply failure, but also against the loss of one mains circuit. Each power supply has its own mains connection and power control, depending on the installed server hardware.**Important -** Please read Safety Information on proper grounding and electrical safety.
# 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.
