7.21. Switches and Jumpers
The product has several jumpers which must be properly configured to ensure correct operation.
Figure 37: Jumper Connector
For a three-pin jumper (see Figure 37), the jumper setting is designated ''1-2'' when the jumper connects pins 1 and 2.
The jumper setting is designated ''2-3'' when pins 2 and 3 are connected and so on. You will see that one of the lines
surrounding a jumper pin is thick, which indicates pin No.1.
To move a jumper from one position to another, use needle-nose pliers or tweezers to pull the pin cap off the pins
and move it to the desired position.
7.21.1. AT / ATX Power Mode Selection (AT_ATX)
The jumper AT_ATX can be used to select AT power mode or ATX power mode.
