In the current setup i connected my SC846 fans directly to the X11SCL-F motherboard. After some time the fans slow down. But FANA seems never to increase speed on load.
But i also noticed 3 fan connectors on the BPN-SAS2-846EL1 backplane. I did a simple test and connected 1 fan to the backplane. Now it seems to stay in the jet-mode.
I find the manuals of the Motherboard/backplane confusing. I hope i understand it correctly.
Do i need a I2C cable between the backplane and motherboard to make this work? Those fans will show up in the BMC sensors list? (with new names, instead of FAN1..FAN5 & FANA).
And in that case, do i need this cable? It seems not validated if i enter my motherboard. https://store.supermicro.com/4-pin-to-4-pin-i2c-power-cable-cbl-cdat-0674.html
At this point i have only 1 SAS cable between the HBA and the backplane. This has some flatbed-cable attached. I assume this is only used for controlling the led's? Because i managed to turn enable a led.
This flatbed-cable is called a "sideband" cable? But SGPIO/I2C cables are also sideband?
And what can i really do with those SGPIO connectors?
