8. USB 2.0 headers
The USB 2.0 headers allow you to connect USB modules for additional USB
2.0 ports. The USB 2.0 headers provide data transfer speeds of up to 480
Mb/s.
DO NOT connect a 1394 cable to the USB connectors. Doing so will
damage the motherboard!
• The USB 2.0 module is purchased separately.
• The pin definitions in this chapter are for reference only. The pin names depend on the
location of the header/jumper/connector.
9. Battery connector
This connector is for the lithium CMOS battery.
10. Backlight Inverter Voltage Selection header
11. Chassis intrusion header
This header is for a chassis-mounted intrusion detection sensor or switch.
Connect one end of the chassis intrusion sensor or switch cable to this
header. The chassis intrusion sensor or switch sends a high-level signal to this
header when a chassis component is removed or replaced. The signal is then
generated as a chassis intrusion event.
12. Clear CMOS header
This header allows you to clear the CMOS RTC RAM data of the system setup information
such as date, time, and system passwords.
To erase the RTC RAM:
1. Turn OFF the computer and unplug the power cord.
2. Use a metal object such as a screwdriver to short the two pins.
3. Plug the power cord and turn ON the computer.
4. Hold down the < Del > key during the boot process and enter BIOS
Setup to re-enter data.
If the steps above do not help, remove the onboard battery and short the two pins again to
clear the CMOS RTC RAM data. After clearing the CMOS, reinstall the battery.
13. COM Port header
This header is for a serial (COM) port. Connect the serial port module
cable to this header, then install the module to a slot opening at the back
of the system chassis.
