Hardware Requirements
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.
Airflow Requirements
The user is required to supply at least one external fan for cooling the multi-host board populated with the OCP 3.0 card. Please refer to Specifications for airflow requirements.
Failure to supply sufficient airflow may cause damage to the product.
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.
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 multi-host OCP 3.0 adapter kit package, place it on an antistatic surface, and verify you have received the following items:
The multi-host OCP 3.0 board
4x MiniSAS Auxiliary boards, with short brackets assembled on each card.
4x Mini-SAS HD cables.
1x USB type A to mini-USB type B cable.
I/O panel (to be used when the multi-host OCP 3.0 board is installed in a server. Currently, this option is not supported).
Check the parts for visible damage that may have occurred during shipping.
Shut down your system if active. Refer to the system documentation for instructions.
Follow the below steps prior to installing the product.
Verify the DIP-switches position is as stated in the below table and figure.

Please note that the following figures are for illustration purposes only.
Place the multi-host board on an antistatic pad.
Install the OCP 3.0 adapter card in the multi-host board.
Prior to installing the OCP 3.0 adapter card in the multi-host board, unscrew the screw as shown in the below figure.
Applying even pressure at both corners of the card, insert the OCP 3.0 card into the multi-host board using the guiding rails until a click sound is heard.
Secure the OCP card with the screw you removed in the previous step.
When the OCP 3.0 adapter is properly seated, the card's golden fingers are connected to the multi-host OCP 3.0 connector.
Connect the external main power connector with the 12V power source.
TBD: What kind of power cable? need pin description.
Should we add anything regarding LED operations?
Install the MiniSAS auxiliary cards in a server and connect them to the multi-host board.
Applying even pressure at both corners of the card, insert the MiniSAS auxiliary cards to a server.
When the MiniSAS auxiliary cards are properly seated, the harness connector is aligned with the slot opening, and the MiniSAS auxiliary faceplate is visible against the system chassis.
Connect the MiniSAS auxiliary cards with the OCP multi-host board using the supplied MiniSAS cables.

Cables and Modules
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 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.
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 Adapter Card LED Operations under the Interfaces section.
Care should be taken as not to impede the air exhaust flow through the ventilation holes. Use cable lengths that 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. The LED indicator will turn off when the cable is unseated.
Kit Power Sequence
instructions.
Install the OCP 3.0 card to the multi-host board and power up.
Install the MiniSAS auxiliary cards and connect them to the multi-host board using the supplied harnesses.
Power up the server.
Powering up the auxiliary cards while the OCP 3.0 card is not powered up may cause serious damage to the cards.
Once powered up, the OCP 3.0 board FRU EEPROM address in multi-host mode is changed to 0x56.
In power down, power down the MiniSAS auxiliary cards and then the OCP 3.0 card.
