22FYP SAS backplane - What does the control cable actually do?

Question

I bought this backplane thinking to build a small storage bay / NAS unit.

The SFF-8087 connectors go to the SAS controller, power goes to power... what does the 16 pin 0G95P6 cable actually do?

Is it actually required to use this backplane?

Hello thanks for choosing Dell and welcome to our community.

Can you send us your server's service tag so that we can know what model you have and see the original configuration?

Respectfully,

@DELL-Young E​ No service tag.  I don't have a Dell server, I have a backplane and am asking a specific question about that part.

I know what the cable is... I am asking what does it do, and is it required to use this backplane as a simple JBOD connection.

What are the signals on the 16 pin connector? What purpose does the cable itself serve?

Hi, it is a power cable that delivers power to the backplane.

@Dell-Martin S​ The 10 pin connector is for power.  The 16 pin connector is what I am inquiring about.
