Auxiliary Panel Header
(18-pin AUX PANEL_1)
(see p.7, No. 9)
This header supports multiple
functions on the front panel,
including the front panel SMB,
internet status indicator and
chassis intrusion pin.
Serial ATA2 Connectors
(Blue)
(SATA_4)
(see p.7, No. 20)
(SATA_5)
(see p.7, No. 21)
SA TA_4
SA TA_5
These two SATA2 connectors
support SATA data cables for
internal storage devices with
up to 3.0 Gb/s data transfer
rate.
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 (6-pin LOCATOR)
This header is for the locator switch and LED on the front panel.
The LOCATORBTN# controls both LOCATORLED1 and LOCATORLED2. When the
Locator button is pressed, both Locator LED 1 and 2 will be turned on.
