Issue Details

I need to turn on or wake up a PXI/PXIe system remotely over Ethernet. Is Wake-on-LAN (WOL) possible with PXI/PXIe? If so, how do I use this feature?
 

Solution

Wake-on-LAN (WOL) is only supported on Windows PXI Express (PXIe) systems. It is not supported for Real Time Pharlap ETS or on standard PXI systems. It also requires that the target has an Ethernet card that uses a 5 volt standby rail in order to monitor network traffic while the PXIe system is shut down.

To configure WOL, you will need to enable the correct Ethernet driver features in the OS on the controller.

PXIe-8105/8106 INTEL Pro controllers:
  1. Go to Device Manager
  2. Right-click the Ethernet Controller and choose Properties
  1. Go to the Advanced tab:
    1. Select Enable PME
    2. Confirm that the Value field is set to Enabled
  1. Select the Wake On Settings and change the Value to Wake on Magic & Directed
  1. Exit out of Properties and shut the controller down.
  2. If the ethernet controller is configured correctly the ethernet lights on the front panel of the PXIe controller will be active when powered down.

PXIe-8130 NVIDIA Controller
  1. Navigate to Device Manager and select the ethernet controller Properties 
  2. Select the Advanced tab and click on the Wake on Magic packet  from the Property box
  3. Confirm the Value field is set to Enabled
  1. Exit out of Properties and shut the controller down.
  2. If the ethernet controller is configured correctly the ethernet lights on the front panel of the PXIe controller will be active when powered down.

Additional Information

Once the network card is properly configured, the attached LabVIEW program can be used to turn on the computer by sending the Magic Packet.  The WOL feature for both of these Ethernet chipsets accept a magic packet of 6 bytes of all 1's followed by 16 repetitions of the MAC address for the controller you want to wake. You need to broadcast a UDP packet with this information to the controller or subnet the controller is on. The attached LabVIEW 8.5 example will work with any PXIe-8105/6 or PXIe-8130 controller.

It is important to note that if there is a power outage, the chassis must be rebooted to return power to the Ethernet port. Most PXIe controllers have a BIOS feature called Restore After Power Loss. When set to Turn On, the controller will automatically power on when AC power is restored.
