optical cables require power from the HCA port (to run the optics, obviously). Not all HCAs have power available at the port. I don't know of a very good way to tell which do. The Topspin/Cisco HCAs are basically OEM versions of Mellanox HCAs so maybe Mellanox can tell you which versions support power. - R. _______________________________________________ general mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
