Cables and Modules

To obtain the list of supported NVIDIA cables for your adapter, please refer to the Cables Reference Table at http://www.nvidia.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.

To uninstall the adapter card, see .Uninstalling the Card

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 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 under theLED Interface

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 under the Interfaces section. LED Interface

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. The LED indicator will turn off when the

cable is unseated.
