<DIV><FONT face=Arial size=2>Hi all,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I don't know if this is the right mailing list to
ask this, but maybe someone can direct me to the right place.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>We are thinking about developing a very simple TCA,
that can connect to a switch and regular HCAs from Mellanox or other
manufacturer.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Can our TCA provide a 1x port, but using
a _physical_ 4x connector?</FONT></DIV>
<DIV><FONT face=Arial size=2>In other words, our TCA will be a 1x SDR TCA,
but we would linke to use a 4x connector, and so use 4x cables to link
it to our switch.</FONT></DIV>
<DIV><FONT face=Arial size=2>In response to Subnet Management Packets, we will
advertise a 1x SDR port, and we will behave exactly as a regular 1x
TCA should do.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>What should we do with the unused physical lanes?
Should we leave them floating? Should we connect them to GND? Or something
other?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Is there something particular that should we do to
get this working?</FONT></DIV></BODY></HTML>
