Hardware Installation

Installation and initialization of ConnectX-5 adapter cards require attention to the mechanical attributes, power specifications, and precautions for electronic equipment.

Please observe all safety warnings to avoid injury and prevent damage to system components. Note that not all warnings are relevant to all models.

Note that not all warnings are relevant to all models.

	General Installation Instructions Read all installation instructions before connecting the equipment to the power source.
	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.
	Equipment Installation This equipment should be installed, replaced, or serviced only by trained and qualified personnel.
	Equipment Disposal The 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.
	Hazardous Radiation Exposure Caution – Use of controls or adjustment or performance of procedures other than those specified herein may result in hazardous radiation exposure.For products with optical ports. CLASS 1 LASER PRODUCT and reference to the most recent laser standards: IEC 60 825-1:1993 + A1:1997 + A2:2001 and EN 60825-1:1994+A1:1996+ A2:20

The installation procedure of ConnectX-5 adapter card kit with Multi-Host involves the following steps:

Hardware Requirements

A system with four available PCI Express x4 slots is required for installing the ConnectX-5 and card and three PCIe Auxiliary cards.

Airflow Requirements

ConnectX-5 adapter card kit is offered with one airflow pattern: from the network ports to the heatsink, as shown below.

Please refer to the "Specifications" chapter for airflow numbers.

Airflow from the network ports to the heatsink:

Software Requirements

• See Operating Systems/Distributions section under the Introduction section.

• Software Stacks - NVIDIA OpenFabric software package MLNX_OFED for Linux. See the Driver Installation section.

1. Unpack the adapter package and place them on an antistatic surface, and verify you have received the following items:

   1. ConnectX-5 Adapter Card, with a short bracket assembled on the card.

   2. 3x PCIe Auxiliary cards, with a short bracket assembled on each of the cards.

   3. 3x Mini-SAS HD cables.

2. Check the parts for visible damage that may have occurred during shipping.

3. 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-5 card, make sure that the system is disconnected from power.

This section provides detailed instructions on how to install your ConnectX-5 adapter card kit in your system.

The ConnectX-5 VPI adapter card kit installation in the system should be planned according to the below figure.

Install the ConnectX-5 main adapter card in the system:

1. 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.

2. Open the system case.

3. Applying even pressure at both corners of the card, insert the card into the PCI Express slot until firmly seated.

   

4. When the adapter is properly seated, the port connectors are aligned with the slot opening, and the adapter faceplate is visible against the system chassis.

   

5. Secure the adapter with the adapter screw.

Install the three PCIe Auxiliary cards in the system:

1. Applying even pressure at both corners of the card, insert the PCIe Auxiliary cards into the available PCI Express x4 slots until firmly seated.

   

2. When the PCIe Auxiliary card is properly seated, the harness connector is aligned with the slot opening, and the PCIe Auxiliary faceplate is visible against the system chassis.

   

Connect the ConnectX-5 Main Adapter Card with each PCIe Auxiliary Cards using the supplied mini SAS harnesses, as shown in the below figure.

Connect the ConnectX-5 Main Adapter Card with each PCIe Auxiliary Cards using the supplied mini SAS harnesses, as shown in the below figure.

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 Adapter Card LED Operations.

4. After plugging in a cable, lock the connector using the latching mechanism particular to the cable vendor. hen data is being transferred the Green LED will blink. See Adapter Card LED Operations 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.

Power up the ConnectX-5 main board, and then, power up the PCIe Auxiliary Cards.

In power down, power down the PCIe auxiliary cards and then the ConnectX-5 card main card.

On Linux

Get the device location on the PCI bus by running lspci and locating lines with the string “NVIDIA Technologies”:

            

            
lspci |grep -i NVIDIA 
Network controller: NVIDIA Technologies MT28800 Family [ConnectX-5]
        

On Windows

1. Open Device Manager on the server. Click Start => Run, and then enter devmgmt.msc.

2. Expand System Devices and locate your NVIDIA ConnectX-5 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.

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 Technologies; and DEV is equal to 1018 (for ConnectX-5) – this is a valid NVIDIA Technologies 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 at the PCI ID repository.
