Safety Precautions
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 device.
Safety Warnings
Safety warnings are provided here in the English language. For safety warnings in other languages, refer to the Adapter Installation Safety Instructions document available on mellanox.com.
Please observe all safety warnings to avoid injury and prevent damage to system components.
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

Pre-installation Checklist
- Verify that your system meets the hardware and software requirements stated above.
- Shut down your system if active.
- After shutting down the system, turn off power and unplug the cord.
- Remove the card from its package. Please note that the card must be placed on an antistatic surface.
- Check the card for visible signs of damage. Do not attempt to install the card if damaged.
Bracket Installation Instructions
The card is usually shipped with a tall bracket installed. If this form factor is suitable for your requirements, you can skip the remainder of this section and move to Card Installation Instructions.
If you need to replace it with the short bracket that is included in the shipping box, please follow the instructions in this section.
Due to risk of damaging the EMI gasket, it is not recommended to replace the bracket more than three times.
To replace the bracket you will need the following parts:
- The new bracket of the proper height
- The 2 screws saved from the removal of the bracket
- The 2 fiber washers saved from the removal of the bracket
Removing the Existing Bracket
Remove the two screws holding the bracket in place. The bracket comes loose from the card.
Be careful not to put stress on the LED.
Save the two screws and the two fiber washers.
Installing the New Bracket
Place the bracket onto the card until the screw holes line up.
Do not force the bracket onto the card. You may have to gently push the LEDs using a small screwdriver to align the LEDs with the holes in the bracket.
- Screw on the bracket using the screws and washers saved from the bracket removal procedure above.
- Make sure that the LEDs are aligned onto the bracket holes.
- Use a torque driver to apply up to 2.9 lbs-in torque on the screws.
Card Installation Instructions
- Open the system case.
- Place the adapter in a standard PCI Express slot.
Applying even pressure at both corners of the card, insert the adapter card into the slot until it is firmly seated. When the adapter is properly seated, the adapter port connectors are aligned with the slot opening, and the adapter faceplate is visible against the system chassis.
Do not use excessive force when seating the card, as this may damage the system or the adapter.
Cables and Modules
To obtain the list of supported cables for your adapter, please refer to the List of Supported Cables in the release notes and http://www.mellanox.com/products/interconnect/cables-configurator.php.
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.
When installing cables make sure that the latches engage.
Always 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 Amber 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 Network LEDs Operation.
- After plugging in a cable, lock the connector using the latching mechanism particular to the cable vendor. When a logical connection is made, the Green LED will light. When data is being transferred the Green LED will blink. See Network LEDs Operation.
- 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.
Xilinx Programming Cable
Xilinx programming cable is not provided by Mellanox, please contact your Xilinx representative for details.
The Xilinx programming cable is a USB to JTAG probe required to directly access the FPGA HW. Please refer to http://www.xilinx.com/products/boards-and-kits/hw-usb-ii-g.html.
It is possible to connect the flat cable that comes with the Xilinx platform cable USB II to the on-board JTAG connector.
The on-board JTAG connector is 9 pins, dual row, 2mm pitch. The flat cable has a female connector 7 pins, dual row, 2mm pitch. The cable should be connected to the on-board connector according to the key in the shroud, (indicated with the yellow rectangle) leaving 2 unconnected pins on each side.
The other end of the Xilinx Platform Cable USB II should be connected to the user’s computer.
