Mounting Jumpers of the Rack iPC Universal and Optimized
You may configure the Rack iPC Universal and Optimized to match the needs of your application by setting jumpers.
NOTE: A pair of needle-nose pliers may be helpful when working with jumpers.
Connectors on the Rack iPC motherboard link it to devices such as hard disk drives and a keyboard. In addition, the board has a number of jumpers used to configure your system for your application. The tables below list the function of each of the board jumpers and connectors. Later sections in this chapter give instructions on setting jumpers.
The figure shows the Rack iPC Universal and Optimized jumpers and connectors:

The Rack iPC motherboard contains a jumper that can erase CMOS data and reset the system BIOS information. Normally this jumper should be set with pins 1-2 closed. If you want to reset the CMOS data, set CMOS1 to 2-3 closed for just a few seconds, and then move the jumper back to 1-2 closed. This procedure resets the CMOS to its default setting.
The table shows the CMOS clear data:

* In the default production mode, there is no lock protection for BIOS. The master region access control setting is FF, users can update the complete BIOS with the ADVSPI tool. The function is same as manufacture mode. BIOS ME (Management engine) function keeps link/remote control. The jumper can be set under AC off PWR status; it cannot be set under standby PWR status.
In production mode with lock protection for BIOS, the master region access control setting is Read:0B, Write:0A. Users cannot update BIOS ME firmware freely. BIOS ME (Management engine) function keeps link/remote control. This setting is only for OEM project requests. The jumper can be set under AC off PWR status, it cannot set under standby PWR status.
In manufacture mode, BIOS has no lock protection function. The master region access control setting is FF, users can update complete BIOS with ADVSPI tool. However, the BIOS ME function does not keep the link/remote control after the BIOS been updated.
The Rack iPC motherboard contains a jumper that provides a chassis open sensor. The buzzer on the motherboard beeps when the case is opened.
