Please connect either end
of VGA_2X8 cable to VGA
header.
A. Front panel SMBus connecting pin (6-1 pin FPSMB)
This 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)
These two 2-pin headers allow you to use the Gigabit internet indicator cable to connect
to the LAN status indicator. When this indicator flickers, it means that the internet is prop-
erly connected.
C. Chassis intrusion pin (2-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 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. The default setting is
set to the CASEOPEN and GND pin; this function is off.
D. Locator LED (4-pin LOCATOR)
This header is for the locator switch and LED on the front panel.
E. System Fault LED (2-pin LOCATOR)
This header is for the Fault LED on the system.
