2.10.4 SM Bus Connector (JFP2 / SNMP)
This connector is reserved for Advantech’s SNMP-1000 HTTP/SNMP Remote Sys-
tem Manager. The SNMP-1000 allows users to monitor the internal voltages, temper-
ature and fans from a remote computer through an Ethernet network.
(JFP2 / SNMP) can be connected to CN19 of SNMP-1000. Please be careful about
the pin assignments, pin 1 must be connected to pin 1 and pin 2 to pin 2 on both ends
of cable.
2.10.5 External speaker (JFP2 / SPEAKER)
(JFP2 / SPEAKER) is a 4-pin connector for an external speaker. If there is no exter-
nal speaker, the PCA-6010 provides an onboard buzzer as an alternative. To enable
the buzzer, set pins 3-4 as closed.

PWR_LED&KEY LOCK)

Lock function. Refer to Appendix B for detailed information on the pin assignments.

where the system is turned on/off by a power button. The second is “AT Power
Mode”, where the system is turned on/off by the switch on the power supply. The third
