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.

Identifying Your Card

Hardware Requirements

Important

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.

A system with a PCI Express x8 FCI B2B connector is required for installing the card.

Important

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.

Airflow Requirements

ConnectX-4 Lx adapter cards are offered with two airflow patterns: from the heatsink to the network ports, and vice versa, as shown below.

Please refer to the Specifications section for airflow numbers for each specific card model.

Important

All cards in the system should be planned with the same airflow direction.

Software Requirements

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.

  • 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-4 Lx card, make sure that the system is disconnected from power.

Check the adapter for visible damage that may have occurred during shipping. Please note that the cards must be placed on an antistatic surface.

Important

Please 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.

This section provides detailed instructions on how to install your adapter card in a system.

Warning

Please note that the following figures are for illustration purposes only.

  1. Before inserting the card in a system, make sure that the system is off and the power cord is not connected to the server. Please follow proper electrical grounding procedures.

  2. Locate an available PCI Express slot for the adapter card. Make sure the adapter clips or screws are open.

  3. Place the adapter card on the clips without applying any pressure.

    image2019-3-3_13-59-20.png

  4. 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.

    image2019-3-3_13-59-38.png

  5. Secure the adapter with the adapter clips or screws.

  6. Close the system case.

Note

To uninstall the adapter card, see Uninstalling the Card.

Cable Installation

  1. All cables can be inserted or removed with the unit powered on.

  2. To insert a cable, press the connector into the port receptacle until the connector is firmly seated.

    1. 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.

    2. 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.

    3. 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.

    4. Make sure that the connector locks in place.

      Warning

      When installing cables make sure that the latches engage.

      Important

      Always install and remove cables by pushing or pulling the cable and connector in a straight line with the card.

  3. After inserting a cable into a port, the Green LED 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 LED Interface under the Interfaces section.

  4. After plugging in a cable, lock the connector using the latching mechanism particular to the cable vendor. When data is being transferred the Green LED will blink. See LED Interface under the Interfaces section.

  5. 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.

  6. 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.

  2. Expand System Devices and locate your NVIDIA ConnectX-4 Lx adapter card.

  3. Right click the mouse on your adapter's row and select Properties to display the adapter card properties window.

  4. Click the Details tab and select Hardware Ids (Windows 2012/R2/2016) from the Property pull-down menu.

    PCI Device (Example)

  5. 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-4 Lx) – this is a valid NVIDIA PCI Device ID.

    Warning

    If the PCI device does not have a NVIDIA adapter ID, return to Step 2 to check another device.

    Warning

    The list of NVIDIA PCI Device IDs can be found in the PCI ID repository at http://pci-ids.ucw.cz/read/PC/15b3.
