IMPORTANT: After a successful power supply firmware download, the managed system turns off for a duration ranging from three to ten minutes to continue updating the firmware. Once the firmware update is complete, the managed system reboots automatically.

CAUTION! Performing an AC power cycle or cold boot during a power supply firmware update, forces the power supply unit into an irrecoverable state and the managed system does not boot.

1. Fixed the improper handing for the periodic harmonic distortion in AC line

Installation instructions
The installation steps are:
1. After running the DUP, the user is asked if it's ok to restart system (Say yes).
2. The system will reboot and go into Lifecycle Controller on its own.
3. Once in Lifecycle Controller, it will schedule tasks (PSU updates). A warning message displays for 12G systems (i.e., do not power down, system will restart on its own).
4. Lifecycle Controller will turn off system. While in standby, this is when PSUs are actually being updated. It is imperative not to disturb/restart manually during this time. Update time can vary but should be approx. 10 min but should add margin to make sure you don't interrupt (some Dups have taken up to 20 minutes. Be Patient).
5. After update, system will turn on by itself.
