UniFi Switch 16 POE-150W keeps powering down - help!

After installing the switch and upgrading the software everything worked fine.  After a few mins it totally powers off.  I can then take out the power lead and reconnect it and the same happens again.  I have changed plugs, leads and there is no temp issue.  

 

I have a simple set up with the switch powering two access points and a wired network in the house.  Is this a set up issue or does it sound like a hardware issue?  I am out of ideas...

Are you getting any overheat notification warnings in the controller?

No overheating alerts.  Just 'disconnection' alerts or 'missed a heartbeat' alerts.

 

Would there be any issue connecting the switch to a Unifi 8 POE-60W I wonder?  I have an AP directly connected to the 16 switch using POE and then a second AP (plus computer, printer etc) connected via the 8 switch.  Shoudl the 8 switch be non-POE instead?

As a test you could disable the PoE on the ports that are connecting the two switches together.

Thanks.  I will try that later.  I was going to disconnect the second switch but will try your suggestion first.  That intuitively makes sense so fingers' crossed.
