Here’s the link for the SRC finder.
It seems to indicate that the IPL is in progress. Is your system attention (orange) light on? Do you have a console available?
the light is off, system not power on
you need to make sure that there is a console in port 0
if twinaxe make sure cable is good.
I have had system halt because it could not find console.
Normally if the system can’t find a console then the system attention light should come on.
