8.From the Display HSL Information screen select F8 (Follow leading port). This changes the information to that of the next resource on the HSL loop starting from cable port 0. Smaller system models may have an internal I/O resource before going to the first I/O tower on the HSL loop.

9.Select F8 (Follow leading port) to display the HSL information. For each I/O tower or system tower along the HSL Loop, at the Display HSL Information display, locate the Mode information of the resource.

Note: If you cannot locate the Mode information, then this HSL resource is not part of a Cluster Resource Group (CRG) and the tower where this HSL I/O bridge resource is located cannot be configured as switchable.

10.Is the mode listed as Private or is the mode not displayed for this resource?

vYes: The tower where this HSL I/O bridge resource is located cannot be configured as switchable. Select F8 again to procede to the next tower.

vNo: The HSL I/O bridge resource has a mode of switchable. The tower is configured as a switchable tower. Continue with the next step of this procedure.

11.Record the HSL loop number, the type-model, and the serial number of the HSL I/O bridge resource.

Notes:

a.You will need the type-model and serial number to identify the HSL I/O bridge on the other system in the HSL Opticonnect loop.

b.When there are multiple towers on the HSL OptiConnect loop, care must be taken to match the physical tower to the HSL Information screen in order, starting from port 0 on the system. Keep in mind that on smaller systems there may be an internal resource before getting to the external cable port.

Determining the power controlling system of a tower

You can determine the power controlling system of a tower by performing the following procedure.
