My IR829 and IR809 devices did not arrive with power adaptors, so I created my own and wrote that up here:https://github.com/DevOps4Networks/IOX-Notes/tree/master/How_To_Power_Up
Since then, I received two PWR-60W-AC-V2= power supples from Cisco that were pre-fitted with Molex connectors. BUT, those Molex connectors do not quite click in, so one can use them, but they will become dislodged quite easily. So, some hacking is required there also, illustrated above.
Meanwhile, the original DIY effort from above for the IR829 was repurposed for the IR809, and that is also illustrated in the GitHub project above.
That might be useful for other people also.
