Its an SGPIO Cable and it communicates with the backplane.
SGPIO - WikiVisually
It basically tells the LEDs to blink on IO and other tasks.

Thanks for the information. I'm reading https://www.supermicro.com/manuals/other/BPN-SAS-826TQ.pdf in the hope of trying to find out how to get the LEDs right.
I've connected a ServeRaid M1015 to the system and 2 SSDs are inside the chassis (not using the bays, i needed to save these 2 bays
). The MB has integrated 2 x SFF-8087 as well and i'm using one of the ports where the breakout cable to cover all the middle row 4 ports on the backplane.
The SFF-8087 break out cable from one of the SAS ports on M1015 is connected to both the 2 SSDs AND to the SAS ports #6 and #9.
SAS ports #0 and #3 is connected with another SFF-8087 break out cable off the 2nd SAS port on M1015, but the SGPIO cable is too short to reach to the backplane.
I've connected the SGPIO from the onboard SFF-8087 to ACT_IN0_7 and the one from M1015 to ACT_ON8_11.
Now the LEDs are all screwed up. I see constant LED on some and no activity LED changes
EDIT: it seems the breakout cables are different when it comes to this: one is 8-pins (so I2C?) , other 9-pins (SGPIO). The backplane is in default SGPIO mode.
