Perhaps your M7098 (UBI) module is set to autoboot

proms upon powerup, and that's why it comes up in run mode. This is a
personal preference thing, but I never have a machine autoboot to
anything other than the console emulator. I then always select the
boot device by hand. Many people instead set the switches on the UBI
to attempt a boot from a particular device upon powerup. This may be
why you power on in run mode. I would suggest that you look at the 10
position dip switch on the UBI and set 1,2, and 7 on and all the rest
off. Then power up and see if you dont get just the console prompt.
Even if you autoboot to run mode you should always be able to get back
to the
console prompt by typing ^P (assuming you front panel switch is not set
to locked).
After ^P you should get '>>>' and then be able to type 'H' to
halt the
CPU if
it is still running, and then run some basic tests 'T/E'.
If after typing ^P you still don't get >>> then something is amiss with your
console module and/or console microprocessor.
and nothing more, no ">>>"
prompt anymore!
Also, the FAULT lamp on the RL02 drive stays ON.
If I was to make a newbie
guess... you have a problem with your RL02
subsystem (drive, cable, or controller) and your UBI is perhaps set to
autoboot the DL prom. So when you power it on it attempts to boot the
RL02 and hangs because of another problem. Setting the switches as
above would identify this possibility. If it then comes up to the
CONSOLE prompt correctly, you can at least know it's time to zero in
on the RL02 subsystem.
