 As mentioned in the other thread, I have now fixed the hardware failure, 
and I'll try to collect information on LBMS reporting sometime this week.  
I've brought additional hardware too in case I couldn't address the issue, 
so I may be able to find out more.  I'll report on my findings once I have 
them.
