We have FDR switches uplinked into an EDR switch. Works fine, but you should be using FDR cables.

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.
