WAKE-ON-LAN (Remote System Wakeup)


The AT-2500 Series adapter provide Wake-On-LAN capability using AMD's Magic Packet™ technology. Magic Packet™ technology is used to remotely wake up a sleeping or powered off PC on a network. This is accomplished by sending a specific packet of information, called a Magic Packet frame, to a node on the network. When a PC capable of receiving the specific frame goes to sleep, it will enable the Magic Packet mode in the AT-2500 Series, and when the LAN Controller receives a Magic Packet frame, the AT-2500 Series will alert the system to wake up. A Magic Packet frame is simply a standard Ethernet frame containing the MAC address of the NIC in the system to be awakened repeated 16 times.  

APM and ACPI environments use different methods to respond to a remote wake-up command. In an APM power-management environment remote system wake-up is accomplished through the system's APM-compliant BIOS and the AT-2500 Series hardware.

When the AT-2500 Series receives a Magic Packet™ containing its MAC address it asserts the WAKEUP signal through the external Wake-on-LAN cable to the system board. APM power control logic then turns the system on and initiates the boot sequence. After the boot sequence the APM-compliant BIOS clears the PME- signal, which resets the WAKEUP signal so that subsequent wakeup events will be detected.

In an ACPI environment remote system wake up is implemented through the combination of an ACPI-compliant OS such as Windows 2000 hardware that is compliant with the PCI power management specification and the AT-2500 Series hardware. When the AT-2500 Series receives a Magic Packet™ containing its MAC address it asserts the PME- signal on the PCI bus.

The system board detects the PME- signal and alerts the ACPI hardware and OS to initiate its wakeup sequence. Note that the WAKEUP signal is also asserted but not required in the ACPI environment.


To enable Wake-On-LAN:


Install the AT-2500 SERIES in an available PCI expansion slot.

1. Connect the WOL cable to the WOL connector on the AT-2500 Series adapter.

2. Locate the WOL connector on your system board.

3. Connect the other end of The WOL connector to your system board WOL connector.

4. Ensure that the connectors are fully seated.

5. Check your system BIOS settings to ensure Power Management and Wake on LAN features are enabled and set correctly.

6. Enable Magic Packet support for the driver by changing the Magic Packet setting under advanced options for the driver.

NOTE: On Intel motherboards both the PME (Power Management Event) and Wake on LAN BIOS options must be enabled.
