PLED (System Power LED):
Connect to the power status indicator on the chassis front panel. The LED
is on when the system is operating. The LED keeps blinking when the sys-
tem is in S1/S3 sleep state. The LED is off when the system is in S4 sleep
state or powered off (S5).
HDLED (Hard Drive Activity LED):
Connect to the hard drive activity LED on the chassis front panel. The LED
is on when the hard drive is reading or writing data.
The front panel design may differ by chassis. A front panel module mainly
consists of power switch, reset switch, power LED, hard drive activity LED,
speaker and etc. When connecting your chassis front panel module to this
header, make sure the wire assignments and the pin assign-ments are
matched correctly.
Auxiliary Panel Header
(18-pin AUX_PANEL1)
(see p.10, No. 15)
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 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.
