XSCF prompt disappeared, Sun M5000

UNIX Solaris
1

Hi, I've got an issue here: After I logon to the xscf prompt of this Sun M5000 and did 'XSCF> version -c xcp', the xscf prompt disappeared. I can't get it back and can't log out.

exit
rebootxscf
logout
#.
#>
#>
~#
~#
exit
sendbreak
exit

I tried to set the Mode Switch to the service position, but no use.

Please help! Thank you!

did the "version -c xcp" returned a value? if yes, what is it?

XSCF prompt disappeared after "version -c xcp" entered.

The other testing Sun M5000's XSCF is working fine.

hmm... sounds like a bug in old xscf firmware... a hard reset (pull power) might be the only solution to reset the xscf.
