SAS expander card not working

My Intel RES2SV240 came in the mail today from a second hand online seller. These things are supposed to just work as soon as plugged in, correct?

I tried it with both an LSI 9211 and 9271; also tried it off the motherboard powered via a molex connector. I tried many combinations of port sockets. My test hard drive is not detected.

The drive is detected when plugged into my raid controller cards directly, so I know the rest of my system is fine. Can I assume the expander is broken, or is there something I'm not doing right?

It should just work. I tested each port of mine when I first got it and the drive showed up each time. I was using it with an IBM M1015 that I flashed to IT Mode

Are you using the correct port(s) as input(s)?

Bought one myself, haven’t tested yet. Heard about necessary firmware updates to make it work properly. Looked up the firmware update process, haven’t had time to implement.

Just to confirm as you didn't mention it, you have the two SFF-8087 to SFF-8087 cables connecting the SAS card and the expander, in the correct slots (some SAS expanders don't care, but check) and it is powered and the drives are connected to an output plug?

If all that is done, is there any lights on the board? I don't know if that expander has an led, but they typically have one.

If not I'm going to say either dead board or firmware problems.

Maybe the SAS cable you are using to connect the raid /HBA card to the expander is bad.

Update firmware. Had to do this for several cards before they would see anything.
