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.
2.16 Connecting to SNMP-1000 remote manager
Use the 6-pin to 8-pin cable to connect the CPU card to SNMP-1000.
This cable comes with the SNMP-1000.
Important: Make sure that the ATX power supply can take
at least a 720 mA load on the 5 V standby lead
(5VSB). If not, you may have difficulty powering
on your system and/or supporting the "Wake-
on-LAN" function.
