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:

This section explains how to set up and maintain the DIGITS Devbox.
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.
Installing the Hard Disks
- Flip open the three latches on the front of the DevBox.
- Insert the three hard disk drives into the slots.
- Close the latches to secure.
To ensure that the hard disks are seated properly:
- Lower the latches just to the point where you need to push them closed.
- Push the hard disks to make sure they are securely seated.
- Push the latches down all the way until they snap in place.
The DevBox is now ready to power up.
Powering Up the DIGITS DevBox
- Connect the power cable supplied to the power connector of the DIGITS DevBox.
- Plug the power adapter into an appropriately rated electrical outlet. The DIGITS DevBox power consumption can reach 1350W under a heavy, multi-GPU workload. Be sure the DevBox is connected to an adequately rated circuit to avoid overloading the circuit.
- Connect the keyboard and mouse (not included).
- Connect the monitor (not included).
Depending on your monitor, connect it to either the DisplayPort or HDMI connector of the graphics card located at the “top” position in the DevBox.
- Connect a network cable.
- Press and release the power button on the DIGITS DevBox.
The first time you power on the DevBox and enter Ubuntu, there are a few system setup steps to go through, such as agreeing to the NVIDIA cuDNN and CUDA software licenses agreements, specifying your time zone, and setting up your system user name and password. After that, the Welcome screen appears while the system processes the initialization. This may take a few minutes. Wait for this step to complete, and then you can log in to the system and start using the DevBox.
After logging in, the Ubuntu desktop appears and contains shortcuts to DIGITS DevBox Software Release Notes, the DIGITS DevBox User Guide, DIGITS Tutorial, and the NVIDIA DIGITS software.
You will be notified automatically of software updates when they are available. Click the notification balloon and follow the prompts to update the software.
To use two displays:
- Connect both displays to the GPU in the top position of the DevBox.
- Turn on the Devbox and log in.
The two displays will be activated automatically.
The desktop controls appear on the primary display.
- To adjust the display configuration, such as switching primary displays or changing monitor positions, open the System Settings
window, then double-click Displays.
The Displays window opens where you can make your display changes.
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.
How to Replace one of the RAID 5 Hard Disks
To replace one of the RAID 5 hard disk, do the following:
- Power down the DevBox.
- On the front of the DevBox, flip open the latch for the hard disk that you want to replace.
Opening the latch is a two-step process.
- First pull down on the tab to unlock the latch:
- Then swing the latch up:
As you swing the latch all the way up, the hard disk unseats itself.
- Grab the hard disk and pull it straight out.
- Insert the replacement hard disk into the slot.
- Close the latch to secure.
To ensure that the hard disk is inserted properly:
- Lower the latch just to the point where you need to push it closed.
- Push the hard disk to make sure it is securely seated.
- Push the latch down all the way until it snaps in place.
You can now power up your DevBox and rebuild the array as described in the following section.
How to Rebuild RAID 5 Array with new Hard Disk
After you have replaced the degraded or failing RAID 5 disk with a new one, turn on the DevBox and then rebuild the RAID 5 array as follows:
- At the Ubuntu window, click the search icon and then enter “disks” in the search bar.
The Disks window shows the status of the array.
- Click the Settings icon and then click RAID Disks from the menu.
- From the RAID Disks window, select the disk to add from the list.
- Click Add when asked if you are sure you want to add the disk to the array.
- At the Authenticate dialog, enter the password and then click Authenticate.
After authentication the Disks page will show the recovery progress of the array.
When completed, the Disks page shows the state of the working array.

- You must use a power cord rated for your product and for the voltage and current marked on the electrical ratings label of the product. The voltage and current rating of the cord must be greater than the voltage and current rating marked on the product.
- Make sure that the total ampere rating of all products plugged into an extension cord or power strip does not exceed 80 percent of the ampere ratings limit for the extension cord or power strip.
- The product is equipped with a three-wire electrical grounding-type plug which has a third pin for ground. This plug only fits into a grounded electrical power outlet.
- Plug the power cord into a grounded (earthed) electrical outlet that is easily accessible at all times.
- Do not disable the power cord grounding plug. The grounding plug is an important safety feature.
- Do not place objects on AC power cords or cables. Arrange them so that no one may accidentally step on or trip over them.
- Do not pull on a cord or cable. When unplugging from the electrical outlet, grasp the cord by the plug.
- When possible, use one hand only to connect or disconnect cables.
- Do not modify power cables or plugs. Consult a licensed electrician or your power company for site modifications.
- Ensure that the voltage and frequency of your power source match the voltage and frequency inscribed on the equipment’s electrical rating label. If you have the question about the type of power source to use, contact your authorized service.
