In the EXOS Hardware Installation Guide;
In the IRIS, the QSFP+ DAC are available from 0.5m to 5m lengths.
Won't the QSFP+ DAC work on the X590 switches for V160 stacking?

Aah, now I understand. 😄
Well, the Stacking section in the EXOS User Guide (ExtremeXOS® User Guide Version 31.3 > Configuring Stacked Switches > Introduction to Stacking > Available Stacking Methods) also states that QSFP+ is supported:
This is only the case for EXOS 30.2 and above. For 22.6 and 22.7 QSFP+ is not listed for X590, only QSFP28.
I would conclude that QSFP+ is supported, with 30.2+.
Where exactly did you find the information (screenshot) in your initial post?
It's on the page 203 of the EXOS Hardware Installation Guide.
So now it's confirmed. Great thanks!

Dear Stefan,
I need to confirm this because the compatibility matrix shows this; says it’s compatible.
Hi
I think it’s pretty clear. Only QSFP28 possible, not QSFP+.
Best regards
Stefan
