UPBv2 does not Power NUC 11 at Power-on
Posted: Thu Jun 16, 2022 7:33 pm
Hello,
I am a new user of the UPBv2 and just installed an Intel NUC 11 I want to power from the always-on 12V port from the UPBv2.
But it doesn't work always - what do I mean with that?
The whole power of my astronomical setup is behind a Relay Switch. Only if I switch on this relay, the 240V power is available at the mount, telescope etc.
If I turn the relay on, I can hear the 12V power supply sending 12V to the devices, including the Intel NUC 11, indicator: the LED of the power switch is lighting up.
But after a second, it goes off again, and the NUC is not starting (BIOS settings are correct, if I am using the original 19V power Supply behind the relay, it fires up the NUC.)
My backup idea was to send a WOL magic packet to the NUC, but it still stays off (the NUC seems completely off power as even the LEDs on the RJ45 LAN port don't light or blink.)
And even if I push the power-on button the NUC doesn't start.
Only way to fire it up is: pull off the 12V cable from the always-on port on the UPBv2 and plug it in again, then the NUC is starting as expected. Not an ideal workflow when planning to operate the setup completely remotely.
Any idea how to solve this?
Unity Software reports an output voltage (when the NUC is running) of 12.7V, the PSU used is rated at 20Amps.
Thank you,
Herwig
