Table 1. power command
Function	What it does	Command	Valid targets
Power on	Turns on the specified command target.	`power -on` Command use restricted (see Commands and user authority).	`-T system:blade[x]` `-T system:switch[x]` where x is the blade server or I/O-module bay.
Power on to command console	Opens a command console with an SOL session when the specified blade server is turned on.	`power -on -c` Command use restricted (see Commands and user authority).	`-T system:blade[x]` where x is the blade server bay number.
Power off	Turns off the specified command target.	`power -off` Command use restricted (see Commands and user authority).	`-T system:blade[x]` `-T system:switch[x]` where x is the blade server, I/O-module bay, or network clock module number.
Shutdown and power off blade server	Shuts down the operating system and turns off the specified blade server.	`power -softoff` Command use restricted (see Commands and user authority).	`-T system:blade[x]` where x is the blade server number.
Power cycle	Cycles power for the specified blade server or I/O module. If the blade server or I/O module is off, it will turn on. If the blade server or I/O module is on, it will turn off and then turn on.	`power -cycle` Command use restricted (see Commands and user authority).	`-T system:blade[x]` `-T system:switch[x]` where x is the blade server or I/O-module bay number.
Power cycle to command console	Cycles power for the specified blade server. If the blade server is off, it opens a command console with an SOL session when it is turned on. If the blade server is on, it will turn off and then turn on.	`power -cycle -c` Command use restricted (see Commands and user authority).	`-T system:blade[x]` where x is the blade server bay number.
Display power state	Displays the current power state for the specified blade server or I/O module. Possible return values are off, on, standby, or hibernate.	`power -state`	`-T system:blade[x]` `-T system:switch[x]` where x is the blade server or I/O-module bay number.
Enable / disable Wake on LAN globally	Enables or disables Wake on LAN globally for all blade servers.	`power -wol` state where state is `enabled` or `disabled`. Command use restricted (see Commands and user authority).	`-T system`
Enable / disable Wake on LAN for blade server	Enables or disables Wake on LAN for the specified blade server.	`power -wol` state where state is `enabled` or `disabled`. Command use restricted (see Commands and user authority).	`-T system:blade[x]` where x is the blade server bay number.
Enable / disable local power control globally	Enables or disables local power control globally for all blade servers.	`power -local` state where state is `enabled` or `disabled`. Command use restricted (see Commands and user authority).	`-T system`
Enable / disable local power control for blade server	Enables local power control for the specified blade server.	`power -local` state where state is `enabled` or `disabled`. Command use restricted (see Commands and user authority).	`-T system:blade[x]` where x is the blade server bay number.
Display fast POST setting for I/O module	Displays the current fast POST setting for specified I/O module. Note: This target works only for some I/O modules.	`power`	`-T system:switch[x]` where x is the I/O-module bay number.
Enable / disable fast POST for I/O module	Enables or disables fast POST globally for the specified I/O module. Note: This option works only for some I/O modules.	`power -fp` state where state is `enabled` or `disabled`. Command use restricted (see Commands and user authority).	`-T system:switch[x]` where x is the I/O-module bay number.
Display POST status for I/O module	Displays the POST status for the specified I/O module. If the command is run while POST is in progress, it returns the level of POST that is currently in process. If the command is run after POST is complete, it displays one of the following return values: The `POST results could not be read.` message displays if there was an internal error during POST. The `POST results not complete: hex_code` message displays if POST results are not available after POST completes. If POST returns valid results, one of the following messages displays: `hex_code: Base internal function failure detected.` `hex_code: Internal interface failure detected.` `hex_code: External interface failure detected.` `hex_code: Module completed POST successfully.` `hex_code: Cannot decode POST result code.` The `Invalid POST results.` message displays if none of the above conditions is true. Where hex_code is a hexadecimal code. See the documentation that comes with your I/O module for information. Note: This command option is not supported for serial concentrator I/O modules.	`power -state -post`	`-T system:switch[x]` where x is the I/O-module bay number.

Example:

To display the power state for the blade server in blade bay 5, while this blade server is set as the persistent command environment, at the system:blade[5]> prompt, type

                  power -state

To turn on the blade server in blade bay 5, while this blade server is set as the persistent command environment, at the system:blade[5]> prompt, type

                  power -on

To display the power state for the blade server in blade bay 5 again, while this blade server is set as the persistent command environment, at the system:blade[5]> prompt, type

                  power -state

The following example shows the information that is returned from these three commands:

               system:blade[5]> power -state
Off
system:blade[5]> power -on
OK
system:blade[5]> power -state
On
system:blade[5]>
