Power Control WOL task - What else is needed

Customer wants to wake-up any machines that are turned off prior to delivery of patches.  However, as it is undesirable to send broadcast WOL to every machine on a local & remote subnets, I don't want to use the option within policy and I've tried to use the instructions outlined in the following article: https://support.symantec.com/en_US/article.TECH199794.html

Per instructions, I've done the following:

1. Created a Power Control WOL task under Manage > Jobs and Tasks.  
2. Modified the Power Control WOL task with following settings:
3. Power Command = Wake up (send Wake-On-LAN)
4. Port for WOL packet = TCP/IP port in Global Agent Settings
5. Created Server Jobs to run a specific time & immediately for a specific target using the Power Control WOL Task - failed
6. Created "Client Jobs  to run a specific time & immediately for a specific target using the Power Control WOL Task - failed
7. Created "Client Task Schedule" to run a specific time & immediately for a specific target using the Power Control WOL Task - failed

 NS server is running Version 7.1.8400

WOL has been enabled in BIOS for both test machines.

What am I missing?  Thanks.
