I power my 271 on with IP commands and then use the trigger out of the 271 to power on the Trinnov. This has worked much more reliably in my system as at the time the wake on lan commands for the Trinnov didn't seem to be as reliable if the Trinnov had not been powered on for some time.

A red led on the power button for a digital input setup means the 271 is not receiving a valid signal.
