A 2x15 ribbon cable is required to connect between the Alveo data center accelerator card and the programming module. See Programming Cable.
Connecting the Ribbon Cable
When connecting the ribbon cable and programming module, align the cable key with the spacing on the maintenance connector. The cable key is shown in the following image.
Debug-port enabled Alveo data center accelerator cards have a maintenance connector that attaches to the corresponding connector on the programming module through the ribbon cable. The corresponding connector on the programming module is shown in Figure 2. Figure 3 shows the ribbon cable attaching to the 2x15-pin maintenance connector of the Alveo U50 data center accelerator card.
When attaching the cable, apply gentle pressure and ensure the cable has a tight connection.
The Alveo U25 card requires the adapter card (shown in the following image) to convert the U25 debug edge connector to the 2x15-pin connector format. Prior to connecting the adapter to the debug port of the U25 card, attach the six-inch ribbon cable to the adapter card.
With the ribbon cable attached to the adapter card, gently connect the adapter card to the U25 debug port, found at the top of the card as shown in the following figure.
Disconnecting the Ribbon Cable
When removing the ribbon from the Alveo card, adapter card, or the programming module, firmly hold the ribbon connector and pull the cable out in a straight line. Twisting or rotating the connector will damage the connector pins on the Alveo data center accelerator card or the programming module.
