Safety instructions
Use the following safety guidelines to help protect your computer from potential damage and to
help to ensure your personal safety. Unless otherwise noted, each procedure included in this
document assumes that the following conditions exist:
You have read the safety information that shipped with your computer.
A component can be replaced or, if purchased separately, installed by performing the
removal procedure in reverse order.
WARNING: Disconnect all power sources before opening the computer cover or
panels. After you finish working inside the computer, replace all covers, panels,
and screws before connecting to the power source.
CAUTION: Handle components and cards with care. Do not touch the components or
contacts on a card. Hold a card by its edges or by its metal mounting bracket. Hold
a component such as a processor by its edges, not by its pins.
Before servicing Tensor-PC
To avoid damaging Tensor-PC, perform the following steps before you begin working inside the
computer.
1. Ensure that you follow the Safety instructions.
2. Turn off your computer, see Turning off Tensor-PC.
3. Open Tensor-PC’s top cover.
CAUTION: Before touching anything inside your computer, ground yourself by
touching an unpainted metal surface of the computer. While you work, periodically
touch an unpainted metal surface to dissipate static electricity, which could harm
internal components.
Turning off Tensor-PC
Ensure that the computer and all attached devices are turned off. If your computer and attached
devices did not automatically turn off when you shut down your operating system, press and hold
the power button for about 6 seconds to turn them off. Unplug the device from power source.
CAUTION: To avoid losing data, save and close all open files and exit all open
programs before you turn off your computer.

Consignes de sécurité
Utilisez les consignes de sécurité suivantes pour protéger votre ordinateur contre les dommages
potentiels et pour assurer votre sécurité personnelle. Sauf indication contraire, chaque
procédure incluse dans ce document suppose que vous avez lu les informations de sécurité
fournies avec votre ordinateur.
AVERTISSEMENT: débranchez toutes les sources d'alimentation avant d'ouvrir le capot ou
les panneaux de l'ordinateur. Une fois que vous avez fini de travailler à l'intérieur de
l'ordinateur, remettez en place tous les capots, panneaux et vis avant de vous connecter à la
source d'alimentation.
ATTENTION: certaines réparations ne peuvent être effectuées que par un technicien de
maintenance agréé. Vous devez effectuer le dépannage et les réparations simples
uniquement comme autorisé dans la documentation de votre produit ou selon les instructions de
l'équipe de service et d'assistance en ligne ou par téléphone. Les dommages dus à un entretien
non autorisé par Compulab ne sont pas couverts par votre garantie. Lisez et suivez les
consignes de sécurité fournies avec le produit.
PRÉCAUTION: pour éviter les décharges électrostatiques et éviter que les composants
internes ne soient endommagés par les décharges électrostatiques lorsque vous touchez
l'ordinateur ou ses composants, reliez-vous à la terre à l'aide d'un bracelet
antistatique ou en touchant périodiquement une surface métallique non peinte, comme un
connecteur à l'arrière de l'ordinateur.
ATTENTION: Manipulez les composants et les cartes avec soin. Ne touchez pas les
composants ou les contacts d'une carte. Tenez une carte par ses bords ou par son support
de montage métallique. Tenez un composant tel qu'un processeur par ses bords et non par ses
broches.
ATTENTION: lorsque vous déconnectez un câble, tirez sur son connecteur ou sur sa
languette, pas sur le câble lui-même. Certains câbles ont des connecteurs avec des
languettes de verrouillage; si vous déconnectez ce type de câble, appuyez sur les
languettes de verrouillage avant de déconnecter le câble. Lorsque vous séparez les connecteurs,
maintenez-les uniformément alignés pour éviter de plier les broches du connecteur. De plus,
avant de connecter un câble, assurez-vous que les deux connecteurs soient correctement orientés
et alignés
ATTENTION: Seuls les emetteurs optiques laser certifiés IEC/EN 60825-1 et reconnus comme
CDRH classe 1 devraient etre utilisés avec la carte FACET FC-OPLN https://fit-

Quick Start Guide
By default Tensor-PC models are sold without a storage and RAM. To install storage/RAM please
consult “Installation and Service” below.
Choosing placement for Tensor-PC
Please consider the following when placing Tensor-PC
Do not place Tensor-PC in a small closed space having no airflow
Allow at least 10 cm of clearance on left, right and top for effective airflow
The main (best) position it horizontal. However the device can be positioned vertically
too
NOTE: Tensor-PC is designed to be positioned horizontally.
Operating Tensor-PC in vertical position will reduce its cooling efficiency.
Connecting Tensor-PC
Connect monitor to Tensor-PC DisplayPort or HDMI connector (use the HDMI to DVI adapter if
needed)
Connect the USB keyboard and mouse to USB2.0/3.0 connectors
Plug the Ethernet cable into the Ethernet connector
For models with WiFi/cellular: Mount WiFi antennas on the SMA connector by turning it
clockwise repeatedly until the antenna holds firm
Insert the DC plug into Tensor-PC main DC-in jack
Connect the power supply to the AC cord and plug the cord into AC outlet
Tensor-PC with Windows pre-installed
Upon first power-up, you will be guided through the Windows Welcome procedure which is self-
explanatory. The Windows serial number is printed on the Windows label.
Tensor-PC with Linux pre-installed
Linux loads automatically on power up. Upon boot you will be guided through the Linux Mint first-
boot setup procedure.

Tensor-PC devices and installation
Open Tensor-PC for service
To access Tensor-PC internal devices follow the steps below:
1. Shut down the computer and disconnect PSU
2. Unscrew four Phillips screws holding the bottom cover
3. Remove the bottom cover

Hayetsira St. 17, Yokneam, Israel
Tel: [phone] | Fax: [phone] | www.fit-iot.com
WARNING: Only technically skilled person should open and service the Tensor-PC!
RTC Battery (3, 4)
The RTC battery of Tensor-PC is intended to maintain power to the internal Real Time Clock
circuitry.
Tensor-PC can work without a battery, or when the battery is dead. At these situations, the
internal clock won’t be kept on main power loss, and the boot after power loss may take a few
second longer.
In order to replace a depleted RTC battery (4), while the bottom cover is removed and power
from PSU is disconnected, remove the battery wire from the RTC BAT socket on SBC (3) and
replace with the new one.
WARNING: Risk of explosion if the battery is replaced by incorrect type.
RAM (1, 2)
Tensor-PC motherboard features two SODIMM DDR4 slots supporting DDR4-2400.
Tensor-PC supports up to 64 GB in 2x 32 GB configuration.
Both ECC and Non-ECC RAM is supported
Important note: Buffered (registered) RAM is not supported in Tensor-PC.

Storage
NVMe
Tensor-PC supports up to 8 NVMe M.2 2280 devices, each with PCIe 3 x4 interface
The NVMe cards are installed by fastening each to the TEL-NVME element as described below.
Note: In case you have received an assembled flat cable on an aluminum TEL element (without NVMe module), you
must firstly de-touch the flat cable from the plate by unscrewing two fillips screws as shown below:
1. Remove protective film from the pink heatsink

Tel: [phone] | Fax: [phone] | www.fit-iot.com
2. Tighten the red spacer with a Phillips screw (left about 2mm gap between spacer and a screw
head)
3. Insert the NVMe card at an angle into the appropriate socket on the flat
cable.
