Sun 280R unable to boot

I have a problem with one of my Sun 280R servers.

I'm unable to boot it. I've managed to get to the {ok} prompt from the RSC card.

Please see output below

ok show-devs
/virtual-memory
/memory
/aliases
/options
/openprom
/chosen
/packages
/openprom/client-services
/packages/dropins
/packages/SUNW,debug
/packages/terminal-emulator
/packages/disk-label
/packages/deblocker
/packages/SUNW,builtin-drivers
ok showdevs

Is my motherboard a goner?

What happens, if you try to enter boot at the ok-prompt?

It said "boot command has been disabled"

Turns out the server somehow re-directed the console back to keyboard and screen, so my RSC interface was "disabled".

Solution was to access the server physically, redirect output back to rsc-console and now everything is fine.
