Auxiliary Panel Header
(18-pin AUX_PANEL1)
(see p.6, No. 7)
A. Front panel SMBus connecting pin (6-pin FPSMB)
his header allows you to connect SMBus (System Management Bus) equipment. It can
be used for communication between peripheral equipment in the system, which has slower
transmission rates, and power management equipment.
B. Internet status indicator (2-pin LAN1_LED, LAN2_LED)
hese two 2-pin headers allow you to use the Gigabit internet indicator cable to connect
to the LAN status indicator. When this indicator lickers, it means that the internet is prop-
erly connected.
C. Chassis intrusion pin (2-pin CHASSIS)
his 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 intru-
sion 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. he default setting is
