Auxiliary Panel Header
(18-pin AUX PANEL1)
(see p.6, No. 21)
is header supports multiple
functions on the front panel,
including the front panel SMB,
internet status indicator and
chassis intrusion pin.
A. Front panel SMBus connecting pin (6-1 pin FPSMB)
is 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)
ese two 2-pin headers allow you to use the Gigabit internet indicator cable to connect
to the LAN status indicator. When this indicator ickers, it means that the internet is prop-
erly connected.
C. Chassis intrusion pin (2-pin CHASSIS)
is 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. e default setting is
set to the CASEOPEN and GND pin; this function is o.
D. Locator LED (4-pin LOCATOR)
is header is for the locator switch and LED on the front panel.
E. System Fault LED (2-pin LOCATOR)
is header is for the Fault LED on the system.
