If your Mac locks up or becomes unavailable, you should first use the Power Management ‘Hard Reboot’ feature included with every dedicated server subscription at MacStadium via your control panel. Click a subscription, then click the Actions button, then Hard Reboot.
By clicking this button, a signal is sent to an APC-switched PDU power outlet dedicated to your Mac in our data center. The APC PDU will drop power for a few seconds and then restore power. Read this tutorial for more information about rebooting and scheduling a daily self-power via operating system settings.
