sc> poweron
Host poweron is disabled due to:
SCC is not valid or is not present.

Cause

Bad SCSI Power Cable is the most likely faulty part.

Solution

The SCSI Power Cable may need to be replaced.

This cable is part of the Internal Cable Kit - PN 560-2825 [F]

Bad SCSI Power Cable is most likely FRU, but is possible that other components along the red line below are at fault instead. Wiring Diagram taken from Oracle System Handbook.
