Use the poweron command to power on the server. If the host server's keyswitch is in the Off position, or if the server is already powered on, this command has no effect.
Note: You must have r level user permission to use this command.
At the sc> prompt, type the following command:
sc> poweron
Note: If you have just used the poweroff command to power down the host server, ALOM issues the following message:
SC Alert: Host system has shut down.
Wait until you see the message before powering the system back on.
To turn on power to a specific FRU (field-replaceable unit) in the server, type the following command:
sc> poweron fru
where fru is the name of the FRU you want to power on.
For example, to turn power on to Power Supply 0, type:
sc> poweron PS0
The poweron command uses one option: fru.
Specifying the fru option powers on the specified FRU. For example, you can use this command when a power supply is replaced in the host server. ALOM supports the following FRUs.
| Value | Description |
| PS0 | Powers on Power Supply 0 in the host server. |
| PS1 | Powers on Power Supply 1 in the host server. |
| PS2 | Powers on Power Supply 2 in the host server. |
| PS3 | Powers on Power Supply 3 in the host server. |
