Installation

Installation and initialization of the system require attention to the normal mechanical, power, and thermal precautions for rack-mounted equipment.

Warning

The rack mounting holes conform to the EIA-310 standard for 19-inch racks. Take precautions to guarantee proper ventilation in order to maintain good airflow at ambient temperature.

Warning
  • Unless otherwise specified, NVIDIA products are designed to work in an environmentally controlled data center with low levels of gaseous and dust (particulate) contamination.

  • The operation environment should meet severity level G1 as per ISA 71.04 for gaseous contamination and ISO 14644-1 class 8 for cleanliness level.

Heavy Equipment

This equipment is heavy and should be moved using a mechanical lift to avoid injuries.

image2021-8-11_8-56-28.png

Risk of Electric Shock!

  • With the fan module removed power pins are accessible within the module cavity.
    Do not insert tools or body parts into the fan module cavity.

  • For AC powered switch systems: Disconnecting one power supply only disconnects one module. To isolate the unit completely, all connected power supplies must be disconnected.

Country of Norway Power Restrictions

This unit is intended for connection to a TN power system and an IT power system of Norway only.

NVIDIA systems are offered with two air flow patterns:

  • Power (rear) side inlet to connector side outlet - marked with blue power supplies/fans FRUs’ indicators.

    Air Flow Direction Marking - Power Side Inlet to Connector Side Outlet

    image2021-8-24_14-46-41.png

  • Connector (front) side inlet to power side outlet - marked with red power supplies/fans FRUs’ indicators.

    Air Flow Direction Marking - Connector Side Inlet to Power Side Outlet

    image2021-8-24_14-45-53.png

Important
  • All servers and systems in the same rack should be planned with the same airflow direction.

  • All FRU components need to have the same air flow direction. A mismatch in the air flow will affect the heat dissipation.

The table below provides an air flow color legend and respective OPN designation.
