Ensure that the server is in standby power mode.
To power on the server, do one of the following:
- From the front of the server, press and immediately release the Power button on the server front panel.
- From the Oracle ILOM web interface Summary (home) screen, click Power On.
- From the Oracle ILOM command-line interface (CLI), type:
  start /System
When AC power is applied to the server power inlets, the server boots into standby power mode (for information about discerning the boot status of the server using the front panel indicators, see Server Boot Process and Normal Operating State Indicators).

Note - When the server powers on, the power-on self-test (POST) can take several minutes to complete.
