Deep learning is one of the fastest growing segments in the machine learning/artificial intelligence field. It uses algorithms to model high-level abstractions of data in order to gain meaningful insight for practical application. Such data manipulation has application in various fields, such as computer vision, speech recognition and language processing, and audio recognition.

It takes tremendous processing power to efficiently process such huge amounts of data using deep learning algorithms. To that end, NVIDIA has developed an all-in-one, powerful, energy-efficient, cool, and quiet deskside solution, called the NVIDIA® DIGITS(TM) DevBox.

The DIGITS DevBox combines the world’s best hardware, software, and systems engineering for deep learning in a powerful solution that can fit under your desk. It is a single deskside machine comprised of:

• Four NVIDIA GeForce TITAN X GPUs
• NVIDIA DIGITS software: Interactive Deep Learning GPU Training System
• Pre-installed Ubuntu 14.04.2
• Pre-installed deep learning frameworks – Caffe, Torch, Theano, and BIDMach
• NVIDIA CUDA Deep Learning Neural Network library (cuDNN) v2
• NVIDIA CUDA Toolkit 7.0

CPU

Intel Core i7 processor on an ASUS x99E-WS motherboard with 64 GB DDR4 memory

GPU

Four NVIDIA GeForce TITAN X GPUs, installed with NVIDIA qualified drivers

Operating System and Software

The system comes with the following software and OS pre-installed on the SATA3 SSD:

• Ubuntu 14.04.2
• NVIDIA DIGITS Software
• Caffe, Torch, Theano, and BIDMach deep learning frameworks
• NVIDIA CUDA Toolkit 7.0, including the CUDA Deep Learning Neural Network library (cuDNN) v2.

Storage

3x3 TB RAID 5 hard disk drives with separate PCIe SSD cache.

LEDs on each ethernet port indicate the connection status as described in the following tables.

Be sure to inspect each piece of equipment shipped in the packing box. If anything is missing or damaged, contact NVIDIA.

What’s included with your NVIDIA DIGITS DevBox:

• NVIDIA DIGITS DevBox
• Power Cable
• Three (3) hard disk drives
• DisplayPort-to-DVI adapter
• Welcome Card

The three hard disk drives are packaged separately from the system.

You must install all three hard disk drives into the system prior to powering up the DIGITS DevBox.

To use two displays:

1. Connect both displays to the GPU in the top position of the DevBox.
2. Turn on the Devbox and log in.

   The two displays will be activated automatically.

   The desktop controls appear on the primary display.

3. To adjust the display configuration, such as switching primary displays or changing monitor positions, open the System Settings window, then double-click Displays.

You can easily connect to the DIGITS DevBox and run the DIGITS software over your network by opening a browser and entering http://host name (where "host name" is the host name for your DevBox) or the IP address for your DevBox.

Contact your NVIDIA support group if you need to re-image the OS on the DevBox.

If one of the disk drives from the RAID 5 array fails, you need to replace the failed drive with a new one and then rebuild the array to re-generate the lost data on the newly added drive.

The LEDs for each disk drive in the array indicate the general state of the corresponding disk.

A blue light indicates the disk is powered up properly, while a blank LED indicates the disk is not working.

You can also verify the health of the array by clicking the Ubuntu search icon and then entering “disks” in the search bar.

The Disks window shows the degraded state of the array.

NVIDIA products are designed to operate safely when installed and used according to the product instructions and general safety practices. The guidelines included in this document explain the potential risks associated with computer operation and provide important safety practices designed to minimize these risks. By carefully following the information contained in this document and the specific instructions provided with your product, you can protect yourself from hazards and create a safer computer work environment.

The product is designed and tested to meet IEC 60950-1, the Standard for the Safety of Information Technology Equipment. This also covers the national implementation of IEC 60950-1 based safety standards around the world e.g. UL 60950-1. These standards reduce the risk of injury from the following hazards:

• Electric shock: Hazardous voltage levels contained in parts of the product
• Fire: Overload, temperature, material flammability
• Mechanical: Sharp edges, moving parts, instability
• Energy: Circuits with high energy levels (240 volt amperes) or potential as burn hazards
• Heat: Accessible parts of the product at high temperatures
• Chemical: Chemical fumes and vapors
• Radiation: Noise, ionizing, laser, ultrasonic waves

Retain and follow all product safety and operating instructions. Always refer to the documentation supplied with your equipment. Observe all warnings on the product and in the operating instructions.
