Hi Randy,
Thanks for your suggestions.
The front panel power button works. But uadmin doesn't work as expected.
On a snv_110 system, 'uadmin 3 8' doesn't resume the system, I still
need to use the front panel power button.
With 'uadmin 3 7', system panic on resuming. Console message is as follows.
Restoring the System. Please Wait...
