 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]>
