Grounding Cradlepoint CBA850LP6 in enclosure

I have a Cradlepoint CBA850LP6 I'm mounting in an enclosure with a ground pass-through. It's connecting to a MIMO antenna with a ground connector. I'd like to have common ground for them, plus for ethernet (& PoE)

What's a recommended way to attach the CBA850 to the ground wire in the enclosure? Hook the ground on the power supply barrel connector with a stub barrel? Or is there another ground point?

Did you mount the CBA850 with its cases, or remove them per this TUTORIAL

There does not appear to be a lot of places on the CBA850 or its PCB to attach a ground wire.

I decided to use the Modem backing plate as a grounding point on a previous build.

But, I am not sure if this location can be used unless the router cases have been removed.

Presently, the CBA850 is in the factory case mounted in the enclosure, for ease of repurposing for future deployments.

I'll remove it from the case to reach those points. They're at least closer to where potential surges will arrive than the power supply ground. Thanks!

It may be possible to remove the screw from the bottom of the MC400LP6 and attach a small wire connector to it, and slide back into its position.

Then, again, it may cause too tight of a fit.
