1.Power up the system according to the procedure “System Power Up” on page 58.
2.Open Service Tools \ Repair \ System Configuration \ System and check the revision of the PBU application firmware and update it if necessary according to the procedure in the iCT Hardware programming manual. If a software update is done, the system will automatically perform an X-segment software alignment.
