AC Power Recovery
If the AC power supply of a system is disrupted, the chassis is restored to the previous power state before the AC power loss. The
restoration to the previous power state is the default behavior. The following factors could cause the disruption:
• power outage
• power cables pulled from the power supply units (PSUs)
• power distribution unit (PDU) outage
If the Budget/Redundancy Configuration → Disable AC Power Recovery option is selected, the chassis remains powered off
after the AC recovery.
In case, the blade servers are not configured to automatic power-up, you may have to power them on manually.

You can remotely perform power management actions for multiple servers at a time or an individual server in the chassis.
