Is there a way to tell if my silverjaw lure has power going to it when I connect it to the Minnowboard Max? I don't see any led lights turn on.<br class="">
<br class="">
I have a rather unusual setup with my minnowboard max. I'm trying to connect a NVMe PCIe SSD to the silverjaw lure by using a "PCIe x1 to mPCIe" adapter on the mPCIe slot.<br class="">
I'm not able to see this SSD. As a first step, I'm trying to see if there are any power issues.<br class="">
<br class="">
Thanks!<br class="">
