Having trouble console into a QM8790 switch. I don’t have an official Mellanox console cable.
From documentation the QM8790 switch is supposed to be managed via console port.
The only management port on the machine is a single micro usb port and no RJ45 ports of any kind.
Shouldn’t this port supply RS232 signaling if it acts as a console port?
Some documentation says this port is duel I2C/RS232 if so what cable pinout would work?
Hi
QM8790 is unmanged switch. That means, the switch does not have DISK and OS. So QM8790 does not have Management port. The console port you are mentioning is for other special purpose.
In case QM8790 (Unmanged switch) is only manged by in-band communication channel. That is InifniBand protocol MAD.

Our servers have Connectx-3 card. We install new firmware 27.2012.2234 LTS to MQM8790 and lost connection switch. After reading Release notes we find out that lates LTS releases do not support ConnectX-3. Please help how to downgrade firmware if we have only Connectx-3 cards on servers.
We bought new connесtx-6 card. It solved problem. It is so unusual that the new firmware of the switch stops supporting previously installed and supported cards
