Shutdown after enlisting disable wakeonlan?

I use MAAS with another PXE server (1 for localboot, and the MAAS Pxe Server), and i control which to choose with DHCP.
When i first enlist a machine (first time it PXE-boot on MAAS), the server shutdown. But i can’t wakeonlan this machine, because it seems to be in a deep sleep mode, or something like this (the ethernet is down). When i’m powering my machine manually, i can wakeonlan it without any problems …

How can i change the behaviour after enlisting the machine ? It’s now just shutting down the machine, but maybe i can change some parameters, or even force a reboot, or something else.
