I just got a couple of HP netraid 3si RAID controllers for a very reasonable price. But I don't have any manuals for them. I have found an installation gude, but there are some headers and jumpers I'm not sure what they are for. For example, there is a header that looks like the small power conector used by floppy drves. Is this an auxillary power input? Another is the pins at the rear of the board. There is a marking for SCSI activity, but there are three connections, one for each channel? Then there is the serial connector on board. If anyone has a link to materials about these and any similar items, please let me know. I'd also like to know if I can swap out the 16 meg simm for a larger one
