2.Record the local system type and local system serial number with the information you recorded for the system’s HSL I/O bridge resource name, HSL loop number, type-model, and serial number (See the procedure “Determining if a tower is configured as switchable” on page 149).

3.Record the power controlling System type and System serial number from the SPCN System Information field. The power controlling system’s type, model, and five digits of the serial number are shown in the second line of the tower’s panel.

4.Record the System type and System serial number from the Alternate System Information field. This is the system that the ownership of resources in the tower can be switched to for any resources in the tower that are configured as switchable.

5.Are the Local system type and Local system serial number the same as the SPCN system type and SPCN system serial number?

v Yes = The local system is the power controlling system for the tower. You can perform service procedures requiring power off and power on of the tower from the local system if the local system is also the owner of the switchable resources in this tower. Continue with the next step of this procedure.

vNo = The local system is not the power controlling system for the tower. Service procedures requiring power off and power on of the tower cannot be performed from the local system. Continue with the next step of this procedure.

6.Record which system is the current owner of switchable resources in the tower.

Note: The current owner is determined by locating the term Owner which will be displayed with either the SPCN system information or the Alternate system information. From the Owner system, you can use the Hardware Service Manager (HSM) to work with switchable resources in the tower,
