10. Chassis intrusion connector (4-1 pin CHASSIS1)
This lead is for a chassis designed with intrusion detection feature. This
requires an external detection mechanism such as a chassis intrusion sensor
or microswitch. When you remove any chassis component, the sensor triggers
and sends a high-level signal to this lead to record a chassis intrusion event.
By default, the pins labeled “Chassis Signal” and “Ground” are shorted with a
jumper cap. If you wish to use the chassis intrusion detection feature, remove
the jumper cap from the pins.
11. System panel connector (20-pin PANEL1)
This connector accommodates several system front panel functions.
System Power LED Lead (3-1 pin PLED)
This 3-1 pin connector connects to the system power LED. The LED lights up
when you turn on the system power, and blinks when the system is in sleep
mode.
System Warning Speaker Lead (4-pin SPKR)
This 4-pin connector connects to the case-mounted speaker and allows you to
hear system beeps and warnings.
