I'm trying to install an Adaptec 5405 RAID card into an Intel 1RU server, and I need to figure out how to connect the existing SGPIO connector from the backplane, onto the card itself (at least I assume that's how it should work).
The motherboard of the server is an Intel S3420GPLC board. I've already plugged the Adaptec card into the backplane connectors for each HDD, but I'm struggling to figure out how to connect the HDD LEDs up.
I can see the backplane has an SGPIO 4-pin connector which I believe is being used to communicate with the built-in storage controller on the motherboard (which is not needed anymore), as it connects to an SGPIO connector on the board.
From what I've read, the Adaptec 5405 supports for SGPIO and I2C, and has pins for the LED connection on the card. So it should simply be a matter of connecting the SGPIO connector in the correct fashion.
Can someone advise how I should be plugging this cable into the card? I'm worried about damaging the card and/or board if I do it incorrectly.
