System Installation and Initialization

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

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.

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.

The installation procedure for the system involves the following phases:

Safety Warnings

Prior to the installation, please review the safety warnings. Note that not all warnings may apply to all models.

Safety warnings are provided here in the English language. For safety warnings in other languages, refer to the 1U Switch Installation Safety Instructions document available on mellanox.com.

Safety Warnings (English)

Installation Instructions

Read all installation instructions before connecting the equipment to the power source.

Bodily Injury Due to Weight

Use enough people to safely lift this product. 

Heavy Equipment

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

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.

    In QM97X0/SGX H100 switch systems: for 200-240Vac use only

Over-temperature

This equipment should not be operated in an area with an ambient temperature exceeding the maximum recommended: 45°C (113°F). Moreover, to guarantee proper ventilation, allow at least 8 cm (3 inches) of clearance around the ventilation openings.

Stacking the Chassis

The chassis should not be stacked on any other equipment. If the chassis falls, it can cause bodily injury and equipment damage.

Redundant Power Supply Connection—Electrical Hazard

This product includes a redundant power or a blank in its place. In case of a blank power supply, do not operate the product with the blank cover removed or not securely fastened.

Double Pole/Neutral Fusing

This system has double pole/neutral fusing. Remove all power cords before opening the cover of this product or touching any internal parts.

Multiple Power Inlets

Risk of electric shock and energy hazard. The PSUs are all independent. Disconnect all power supplies to ensure a powered down state inside of the switch platform.

During Lightning—Electrical Hazard

During periods of lightning activity, do not work on the equipment or connect or disconnect cables.

Copper Cable Connecting/Disconnecting

Copper cables are heavy and not flexible, as such they should be carefully attached to or detached from the connectors. Refer to the cable manufacturer for special warnings/instructions.

Rack Mounting and Servicing

When this product is mounted or serviced in a rack, special precautions must be taken to ensure that the system remains stable. In general, the rack should be filled with equipment starting from the bottom to the top.

Equipment Installation

This equipment should be installed, replaced, and/or serviced only by trained and qualified personnel.

Equipment Disposal

Disposal of this equipment should be in accordance to all national laws and regulations.

Local and National Electrical Codes

This equipment should be installed in compliance with local and national electrical codes.

Installation Codes

This device must be installed according to the latest version of the country national electrical codes. For North America, equipment must be installed in accordance to the applicable requirements in the US National Electrical Code and the Canadian Electrical Code.

Battery Replacement

Warning: Replace only with UL Recognized battery, certified for maximum abnormal charging current not less than 4mA. There is a risk of explosion should the battery be replaced with a battery of an incorrect type. Dispose of used batteries according to the instructions.

UL Listed and CSA Certified Power Supply Cord

For North American power connection, select a power supply cord that is UL Listed and CSA Certified, 3 - conductor, [16 AWG], terminated with a molded plug rated at 125 V, [13 A], with a minimum length of 1.5m [six feet] but no longer than 4.5m.
For European connection, select a power supply cord that is internationally harmonized and marked “<HAR>”, 3 - conductor, minimum 1.0 mm2 wire, rated at 300 V, with a PVC insulated jacket. The cord must have a molded plug rated at 250 V, 10 A.

Installation Codes

This device must be installed according to the latest version of the country's national electrical codes. For North America, equipment must be installed in accordance to the applicable requirements in the US National Electrical Code and the Canadian Electrical Code.

Interconnection of Units

Cables for connecting to the unit RS232 and Ethernet Interfaces must be UL certified type DP-1 or DP-2. (Note: when residing in non LPS circuit.)

Overcurrent Protection

A readily accessible Listed branch circuit overcurrent protective device rated 20 A must be incorporated in the building wiring.

Do Not Use the Switch as a Shelf or Work Space

Caution: Slide/rail mounted equipment is not to be used as a shelf or a work space. The rails are not intended for sliding the unit away from the rack. It is for permanent installation at final resting place only, not used for service and maintenance.

Air Flow

  • The following information does not apply to SN2100/SN2010. In the SN2100/SN2010 systems, the fan units are non-replaceable.
  • The drawings are provided for illustration purposes only. The panel and modules design may vary depending on the system. 


The systems are offered with two air flow patterns:

  • Power (rear) side inlet to connector side outlet - marked with blue power supplies/fans FRUs’ handles or blue dots that are placed on the power inlet side.

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

  • Connector (front) side inlet to power side outlet - marked with red power supplies/fans FRUs’ handles or red dots that are placed on the power inlet side. 

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


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.

DirectionDescription and OPN Designation

Connector side inlet to power side outlet. The airflow direction is indicated by red latches or by red dots that are placed on the power inlet side. 
OPN designation is “-R”.

Power side inlet to connector side outlet. The airflow direction is indicated by blue latches or by blue dots that are placed on the power inlet side.
OPN designation is “-F”.
