Important Safety Warnings

Electrical Safety

Danger

Failure to follow these electrical safety instructions may result in electric shock, fire, or damage to the Workstation.

  • Ensure you are connecting the power to an AC power circuit with sufficient capacity to support 15A. Failure to connect to dedicated 15A breaker may result in tripping the breaker, or dangerous operating conditions.

  • Do not share the outlet with other high-power devices. Avoid using household surge strips, extension cords, or multi-outlet power taps; not all are rated for the sustained current of this system.

  • Use only the provided C19 power cable, and ensure it is plugged into a properly grounded outlet. Do not bypass or disable the grounding pin. Using a non-Tenstorrent approved power cable may result in dangerous operating conditions.

  • If the circuit becomes overloaded or if the breaker trips during power-up or operation, immediately disconnect and remove power. Then, have a qualified electrician inspect and verify the circuit’s capacity before resuming setup.

  • Never attempt to reset or bypass a tripped breaker without first confirming the circuit integrity; failure to do so may result in overheating, voltage drop, or irreversible damage.

Electrostatic Discharge Safety

Important

Before opening the TT-QuietBox 2 Blackhole workstation or handling any internal components, you must discharge static electricity from your body to avoid damaging sensitive hardware. Electrostatic discharge can permanently damage Tensix cores, memory modules, or other components. Handle with care and always follow ESD-safe practices.

  • Touch a grounded metal surface, such as a grounded rack, chassis, or power supply casing, before and during internal handling.

  • Ideally, wear an ESD wrist strap connected to a verified ground point.

  • Avoid working on carpeted floors or in low-humidity environments where static buildup is more likely.

  • Do not touch any processor, memory module, connector, or printed circuit board (PCB) circuitry unless absolutely necessary, and only after properly discharging.

Other Notices to Users

  • This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation.

  • This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation.

  • Changes or modifications to this Workstation which are not expressly approved by Tenstorrent may void the user’s authority to operate it. Tenstorrent cannot accept responsibility for any failure to satisfy any Safety, EMC or regulatory requirements that result from non-approved modification of the product, including the fitting of non-Tenstorrent cards, cables, or any other hardware or software modification which may affect compliance. To avoid damage and personal injury, only use Tenstorrent approved hardware with this device.

  • Do not use the TT-QuietBox 2 in a way that it was not designed to be used.
