SUN is hung/dead
What do you do if the system will not respond to commands? I'm using SUN Fire v210. We had a power hit, so i think it caused a problem. The monitor does not come up anymore. So i plugged in on a laptop via serial port, rebooted. The system seems to start to boot, but comes up to message "SC Request to Send Break to Host" and stops.
Anything I enter results in a prompt {0}ok and afterwords, anything i type at that prompt makes no effect. Can't even do a graceful reboot.

The problem is that no matter waht i type at the {0}ok prompt, I return to the prompt. The system does not do anything. it ignores all my inputs. I can't get past the point of {0}ok

OPB is firmware. If OBP is ignoring valid OBP commands, you must have a hardware problem. I would suspect communication bewteen the laptop and the system. Check the parameters in the laptop. 9600 baud? 8 data bits? 1 stop bit?

Doesn't the appearance of the ok prompt on the laptop imply communication?

If this happens to be the case then have you tried :
1) booting from cdrom
2) powering off and on (switching the key)

It does not guarantee that the laptop is generating characters that the system can understand.
