<p>We haven't had any problems with plugging FDR stuff into and EDR
switch. It does downgrade the connections but still works.</p>

Heya,<br>
<br>
I do very much the same QSFP28-EDR 100G adapter cards into
QSFP+-FDR 56G just with the use of a cable. I even QSFP+-FDR to 4x
SFP+-10G using various brocade, mellanox, chelsio hardware and
have never come out worse.<br>
<br>
Some cables can be a bit funny but I have never had issues with
cables branded by NetApp, DELL, CISCO or purchasing coded variants
from suppliers. However FS.com are a valued cable supplier for
anything that I might think could be a bit fickle.<br>
<br>
Allot of the time it is cable compatibility and rarely the
adapters themselves.<br>
<br>
Hope this help you out buddy :) <br>
Kind regards,<br>
Darren Wise<br>

<pre class="k9mail">has anyone plugged a mellanox fdr card into a mellanox edr switch? i
need to connect a server that doesn't have a x16 port so no edr card,
but i do have an fdr card that's x8. i don't need the speed just the
connection, but i've not tried this before. a quick google says it
should work, but i'm loathe to until i hear someone else has.<hr>Beowulf mailing list, <a class="moz-txt-link-abbreviated" href="mailto:Beowulf@beowulf.org">Beowulf@beowulf.org</a> sponsored by Penguin Computing
