Dust monitor checks showed DM#2 (HAM2) and DM#3 (HAM3) offline. 

   Reset DM2 with no problems. 

   DM3 had been knocked off its perch, pulling out the power plug and leaving it hanging by the network cable. No apparent damage done, as it is back in service. 

Note: I have mounting brackets and adapters on order for mounting these dust monitors on microphone stands. When these are deployed the dust monitors will be much better protected.
