Mellanox QSA28 (1/10/25) + ConnectX6 followups

2 Follow-ups please.

In the ConnectX6 “Release Notes” as linked, it states QSA28 is required for 25GbE but they do not say that for the 10/1 GbE. The note about the QSA28 is is in the 25GbE cable section only. “The 25GbE cables can be supported in ConnectX-4 adapter cards only when connected to the MAM1Q00A-QSA28 module.”

  1. So can I assume that using the QSA28 is implied for 25/10/1 and that’s an omission?

  2. Will you be certifying and testing more 100GbE EDR cabling such as cabling from Cisco, Arista?


Hello Gregory,

Many thanks for your inquiry on the Mellanox Community.

We have checked internally regarding your additional questions:

  1. Yes, the adapter should be used for 10 and 1 GbE connections as well (QSA adapter required). This be updated properly in the upcoming f/w RN

  2. With every new f/w release we are expanding our cable support

Many thanks,

Thank You! Perfect!
