10. Addressable Gen 2 headers
The Addressable Gen2 headers allow you to connect individually
addressable RGB WS2812B LED strips or WS2812B based LED strips.
Before you install or remove any component, ensure that the power
supply is switched off or the power cord is detached from the power
supply. Failure to do so may cause severe damage to the motherboard,
peripherals, or components.
• The Addressable Gen2 header supports WS2812B addressable RGB LED strips (5V/
Data/Ground), with a maximum power rating of 3A (5V), and the addressable headers
on this board can handle a combined maximum of 500 LEDs.
• Actual lighting and color will vary with LED strip.
• If your LED strip does not light up, check if the addressable RGB LED strip is
connected in the correct orientation, and the 5V connector is aligned with the 5V
header on the motherboard.
• The addressable RGB LED strip will only light up when the system is powered on.
11. Clear CMOS header
The Clear CMOS header allows you to clear the Real Time Clock (RTC) RAM
in the CMOS, which contains the date, time, system passwords, and system
setup parameters.
To erase the RTC RAM:
1. Turn OFF the computer and unplug the power cord.
2. Short-circuit pin 1-2 with a metal object or jumper cap for about 5-10 seconds.
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.
DO NOT short-circuit the pins except when clearing the RTC RAM. Short-circuiting or
placing a jumper cap will cause system boot failure!
If the steps above do not help, remove the onboard button cell battery and short the two
pins again to clear the CMOS RTC RAM data. After clearing the CMOS, reinstall the button
cell battery.
12. COM Port header
The COM (Serial) Port header allows you to connect a COM port module.
Connect the COM port module cable to this header, then install the module
to a slot opening on the system chassis.
