Ever wondered why 2 hotswap bay lights flash RED?,
I have had this asked as lot as people think it's a fault and even supermicro tell people to unplug the SGPIO connection! It's not a fault at all.
The onboard SATA ports are divided in 2 sections on the motherboard with 2 SGPIO connections. SGPIO#1 is for ports 0-3 and SPGIO#2 is for ports 4-5.
As ports 6-7 don't exist the SGPIO command is being sent to the backplane to flash 2 error/fail LEDs on bays 6/7 to tell you please don't put drives in me as I don't exist.
Just thought i'd put this little bit of info here if anyone needs to know this.
