HP thin client Wake-on-LAN then PXE boot

Hi,

I am deploying t630's and also setting up our HPDM server so it works correctly. I'd like to be able to cause clients to wake up then PXE boot. But how do I set it up to Wake Up, try PXE boot first and if unsuccessful reboot the other way? Also if a client is stuck on "ERROR: No boot disk has been detected or the disk has failed" how can I remotely make it shut down and try again?

Thank You!
