2.15  SM Bus Connector (CN29)
This connector is reserved for Advantech's SNMP-1000 HTTP/SNMP 
Remote System Manager.  The SNMP-1000 allows users to monitor the 
internal voltages, temperature and fans from a remote computer through 
an Ethernet network.  
CN29 can be connected to CN19 of SNMP-1000.  Please be careful about 
the pin assignments, pin 1 must be connected to pin 1 and pin2 to pin 2 on 
both ends of cable.
Note:
If you will not be using an ATX power connector, 
make sure that pins 2-3 of CN20 are closed.

card and expansion cards. 
2. ATX power supplies may power on if certain 
motherboard components or connections are 
touched by metallic objects.
