Jewelry Removal Warning Before you install or remove equipment that is connected to power lines, remove jewelry such as bracelets, necklaces, rings, watches, and so on. Metal objects heat up when connected to power and ground and can meltdown, causing serious burns and/or welding the metal object to the terminals. |
|
|
Over-temperature This equipment should not be operated in an area with an ambient temperature exceeding the maximum recommended: 55°C (131°F). An airflow of 200LFM at this maximum ambient temperature is required for HCA cards and NICs. To guarantee proper airflow, allow at least 8cm (3 inches) of clearance around the ventilation openings. |
|
|
During Lightning - Electrical Hazard During periods of lightning activity, do not work on the equipment or connect or disconnect cables. |
|
|
Copper Cable Connecting/Disconnecting Some 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 and instructions. |

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 operating environment should meet severity level G1 as per ISA 71.04 for gaseous contamination and ISO 14644-1 class 8 for cleanliness level.
Hardware Requirements
For proper operation and performance, please make sure to use a PCIe slot with a corresponding bus width and that can supply sufficient power to your card. Refer to the Specifications section of the manual for more power requirements.
A system with a PCI Express x16 slot is required for installing the card. ConnectX-6 Dx cards for OCP are complaint with automatic hosts-count detection per OCP Mezzanine card v2.0 (http:// www.opencompute.org/wiki/Server/SpecsAndDesigns).
Airflow Requirements
ConnectX-6 Dx adapter cards are offered with two airflow patterns: from the heatsink to the network ports, and vice versa.
Please refer to the "Specifications" chapter for airflow numbers for each specific card model.
All cards in the system should be planned with the same airflow direction.
See Operating Systems/Distributions section under the Introduction section.
Software Stacks - NVIDIA OpenFabric software package MLNX_OFED for Linux, WinOF-2 for Windows, and VMware. See the Driver Installation section.
The adapter is being installed in a system that operates with voltages that can be lethal. Before opening the case of the system, observe the following precautions to avoid injury and prevent damage to system components.
Remove any metallic objects from your hands and wrists.
Make sure to use only insulated tools.
Verify that the system is powered off and is unplugged.
It is strongly recommended to use an ESD strap or other antistatic devices.

Unpack the ConnectX-6 Dx adapter card.
Unpack and remove the ConnectX-6 Dx card. Check the parts for visible damage that may have occurred during shipping. Please note that the cards must be placed on an antistatic surface.
ImportantPlease note that if the card is removed hastily from the antistatic bag, the plastic ziplock may harm the EMI fingers on the networking connector. Carefully remove the card from the antistatic bag to avoid damaging the EMI fingers.
Shut down your system if active:
Turn off the power to the system, and disconnect the power cord. Refer to the system documentation for instructions. Before you install the ConnectX-6 Dx card, make sure that the system is disconnected from power.
This section provides detailed instructions on how to install your adapter card in a system.
Please note that the following figures are for illustration purposes only.
Before installing the card, make sure that the system is off and the power cord is not connected to the server. Please follow proper electrical grounding procedures.
Open the system case.
Make sure the adapter clips or screws are open. Place the adapter card on the clips without applying any pressure.
Applying even pressure on four corners of the card (as shown in the below picture), insert the adapter card into the PCI Express slot until firmly seated.
Secure the adapter with the adapter clip or screw.
To uninstall the adapter card, see Uninstalling the Card.
Cable Installation
All cables can be inserted or removed with the unit powered on.
To insert a cable, press the connector into the port receptacle until the connector is firmly seated.
Support the weight of the cable before connecting the cable to the adapter card. Do this by using a cable holder or tying the cable to the rack.
Determine the correct orientation of the connector to the card before inserting the connector. Do not try and insert the connector upside down. This may damage the adapter card.
Insert the connector into the adapter card. Be careful to insert the connector straight into the cage. Do not apply any torque, up or down, to the connector cage in the adapter card.
Make sure that the connector locks in place.
WarningWhen installing cables make sure that the latches engage.
ImportantAlways install and remove cables by pushing or pulling the cable and connector in a straight line with the card.
After inserting a cable into a port, the Yellow or Green LED0 indicator will light when the physical connection is established (that is, when the unit is powered on and a cable is plugged into the port with the other end of the connector plugged into a functioning port). See Adapter Card LED Operations.
After plugging in a cable, lock the connector using the latching mechanism particular to the cable vendor. When a logical connection is made, Green LED1 will light. When data is being transferred, Green LED1 will blink.
Care should be taken as not to impede the air exhaust flow through the ventilation holes. Use cable lengths which allow for routing horizontally around to the side of the chassis before bending upward or downward in the rack.
To remove a cable, disengage the locks and slowly pull the connector away from the port receptacle. LED indicator will turn off when the cable is unseated.
On Linux
Get the device location on the PCI bus by running lspci and locating lines with the string “Mellanox Technologies”:
|
lspci |grep -i Mellanox |
On Windows
Open Device Manager on the server. Click Start => Run, and then enter devmgmt.msc.
Expand System Devices and locate your NVIDIA ConnectX-6 Dx adapter card.
Right click the mouse on your adapter's row and select Properties to display the adapter card properties window.
Click the Details tab and select Hardware Ids (Windows 2012/R2/2016) from the Property pull-down menu.
PCI Device (Example)
In the Value display box, check the fields VEN and DEV (fields are separated by ‘&’). In the display example above, notice the sub-string “PCI\VEN_15B3&DEV_1003”: VEN is equal to 0x15B3 – this is the Vendor ID of NVIDIA; and DEV is equal to 1018 (for ConnectX-6 Dx) – this is a valid NVIDIA PCI Device ID.
WarningIf the PCI device does not have a adapter ID, return to Step 2 to check another device.
WarningThe list of NVIDIA PCI Device IDs can be found at the PCI ID repository.
Safety Precautions
The adapter is installed in a system that operates with voltages that can be lethal. Before uninstalling the adapter card, please observe the following precautions to avoid injury and prevent damage to system components.
Remove any metallic objects from your hands and wrists.
It is strongly recommended to use an ESD strap or other antistatic devices.
Turn off the system and disconnect the power cord from the server.
