This section provides instructions on how to configure CPEX series by setting the 
jumpers. It also includes CPEX series default settings and options for each jumper. 
 

A jumper is a metal bridge that closes an electrical circuit. It consists of two metal 
pins and a small metal clip (often protected by a plastic cover) that slides over the 
pins to connect them. To CLOSE/SHORT a jumper means connecting the pins of the 
jumper with the plastic clip and to OPEN a jumper means removing the plastic clip 
from the jumper.

Note: The default jumper setting is marked in GREY color. 

 
 
 
 
 
 
 
 
 
 
1.7.2  CMOS clear (CLR_CMOS) 

In case CPEX series fails to boot due to user’s improper BIOS setting, CLR_CMOS 
jumper can be used to clear the CMOS data and reset the system BIOS information 
by shorting pin 2-3 for few seconds and then moving the jumper back to pin 1-2. 
 
If CPEX series shows “CMOS Settings Wrong” message during the boot up, press F1 
to go into the CMOS Setup menu. You may then enter the correct CMOS setting or 
Load Optimal Defaults or Load Failsafe Defaults. Save your changes and exit the 
CMOS Setup menu. 
 
Note:  
1.  In normal operation, pin 1-2 must stay in CLOSED condition. 
2.  Power must be turned OFF before clearing CMOS data
