equipment in the system, which has slower transmission rates, and power
management equipment.
B. Internet status indicator (2-pin LAN1_LED, LAN2_LED)
These two 2-pin headers allow you to use the Gigabit internet indicator
cable to connect to the LAN status indicator. When this indicator fl ickers, it
means that the internet is properly connected.
C. Chassis intrusion pin (4-1 pin CHASSIS)
This header is provided for host computer chassis with chassis intrusion
detection designs. In addition, it must also work with external detection
equipment, such as a chassis intrusion detection sensor or a microswitch.
When this function is activated, if any chassis component movement
occurs, the sensor will immediately detect it and send a signal to this
header, and the system will then record this chassis intrusion event. The
default setting is set to the CASEOPEN and GND pin; this function is off.
