ConnectX-7 Socket Direct (2x PCIe x16) Adapter Card
Cables and Modules
Cable Installation
Before connecting a cable to the adapter card, ensure that the bracket is fastened to the server
chassis using a screw to prevent movement or unplugging of the card when the cable is inserted or
extracted.
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.
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.
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.
Care should be taken so 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.
Identifying the Card in Your System
On Linux
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.
