SSH management restart only shuts the host down

Description of problem:
Using SSH restart causes the host to somewhat shutdown but doesn't bring it back up. Console screen just gets black, but the host is not exactly down (fencing is not working, since from bmc point of view, the host is up) although all apps/services are down.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. use ssh management restart on a host
2. check hosts console
host console is black and the host is not responsive to anything
host is restarted
host is RHEL 7.4 but this was happening on 7.3 as well
The command just open SSH connection to the host and executes 'systemctl reboot', which works fine on my host. How this is connected to serial console and/or power management status of the host depends on actual vendor implementation.
So it the host console/PM behaviour the same when you perform that action manually? If so, then please check you firmware version/settings.
After some investigation I found out it just takes some time (13.5 minutes) to shut the host down so it can boot up again.
