Hi Dmitri and Tony,
thank you both very much for your answers. I'm on my way to rip out a
switch from an old computer case so I can start the master node for the
first time (hopefully without calling the firemen and an ambulance :) ).
I'll setup the BIOS as you've told me: "ON after AC loss". Does that
mean that next time it will be turned on(off) when the PS is turned on(off)?
Hello, Tomislav.
Many PC BIOS's default to PSU in the "previous state" when AC power is
restored, but you can force the state to "on" if you want, which means
that when the AC power is restored, the BIOS will switch the PSU back on
automatically. This is not desirable for a server, but is fine for a
compute node - It's safer to leave a server off after AC power loss.
If I do this, I can power the master with PS on switch, and use the
switch I have for adding another node with the same setup: set it up to
run diskless, set it's BIOS the same way, turn it off, disconnect the
switch and use it for adding another node. Is this OK?
Or, learn to short the pins with a screwdriver like the rest of us ;-)
Bye,
Tony.
