# Connect the Wake on LAN* Power Cable (Optional)

For the Wake on LAN* (WOL) feature to work correctly, the adapter must be connected to a continuous power source. This allows the PRO/100 S adapter to "listen to" the network even when the computer is turned off. To install the WOL power cable, carefully follow the procedure below.

> | WARNING: Turn off and unplug power to the computer before installing the WOL cable. The WOL connector on your motherboard is live when the computer is plugged in to a power outlet. Failure to do so could damage the adapter or computer. Likewise, always turn off and unplug the computer prior to removing an adapter from the computer.

1. Make sure your computer is unplugged from the power outlet.

2. Locate the 3-pin WOL connector on the PRO/100 S adapter. Attach one end of the WOL cable to the adapter as shown in the diagram that follows. Note that the connector is notched so as to prevent incorrect attachment.

3. Locate the WOL connector on your motherboard. The location varies, depending on the vendor and model of motherboard. The WOL connector is usually located near other power connectors, such as the LED
   connectors.

4. Connect the other end of the WOL cable to the connector on the motherboard as shown in the diagram.

5. Replace the computer cover and plug in the power cord.

6. Some computers may require you to change a setting in your computer’s BIOS or Setup program to enable the WOL feature. Check your computer owner’s manual or contact your dealer for more information.

## Using Wake on LAN

The Wake on LAN feature operates according to a published specification. In simple terms, the specification allows designers to build network adapters that are capable of "listening" to network activity even when the computer is turned off.

WOL adapters have a special low-power standby mode that is active when the rest of the computer is without power. The adapter will respond to a special "wake-up" packet sent by another computer or network device. Typically this wake-up packet causes the adapter to signal the computer to power up and run a pre-defined program.

The wake-up packet structure and behavior is defined in a WOL information brief, available on the Web at:
