1.7Jumper Settings

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.

1.7.1 How to set jumpers

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
