Section 4 - Security
Unattended start mode can be set in BIOS to allow the HMC to reboot
without the power-on password following restoration of power after an
unplanned outage. However, the keyboard and mouse at the local console
will remain locked until the power-on password is entered.

Subject: HMC automatic power on after failure?
Folks:
As I've mentioned in the past ... I'm not a hardware guy.
With that said ... how does the HMC respond when power is restored after
a failure?
We've got a scheduled power outage this weekend and will be powering
down all the partitions on the system Friday evening ... if we power off
the HMC, will it automatically boot up when power is restored?
If we leave the HMC powered on (and let it go down when the UPS is
exhausted), will it automatically boot up when power is restored (I know
some PC's have the ability to reboot or remain off after a power loss
based on BIOS setting).
Is there a setting in the HMC to control the power state upon restoration?
