Adaptec RAID 6405E Storage Controller 2271700-R

I got one of these installed on a new build. the red leds along the bottom are moving side to side. not sure if it's an error, help?

does this card support windows 10 and 6tb hard drives?

I would like to deploy this with 4x4TB drives in RAID-5 yielding 12TB. Is that a supported configuration?

Does this controller card ship with a mini-sas to 4xsata cable? or, is the cable sold separately?
