Powering a unit on or off, rebooting a unit

>	Select Hardware -> Units, Units tab. The Units tab displays information on all Management Units, Server Units, HNCs, and Application Units of the SE server configuration.

Notes:

• If, as in the example, at least one AU PQ is available, HW model is followed by an additional Chassis column. In the case of AU PQ, the chassis of the AU and the partitions are each displayed as single units. Actions are only possible for partitions.

• For a configuration consisting of two SE servers in a Management Cluster:

  • The Units menu does not contain a model name (it is displayed in the submenu of the respective SE server instead).

  • The table contains the additional Server column. This column contains the name of the SE server to which the respective unit belongs.

Depending on the status, you use the Units tab to power a unit on or off or reboot it. Depending on the unit type, the following actions are possible:

Unit type	Power on	Reboot	Shutdown	Power off immediately
MU	X	X	X	X
SU /390	X			X
SU x86	X	X	X	X
HNC	X	X	X	X
AU	X		X	X

On an SU /390 without connection to the hardware interface for switching on / off, the Power on or Power off icon is not active and a tool tip displays the cause.
