10. Remove the SCSI backplane:
NOTICE: Note the relative position of each SCSI data cable if more than one cable is attached to the SCSI backplane
NOTICE: When disconnecting the control panel cable, hold the white pull-tab next to the control panel cable connector to prevent damage to the SCSI
backplane or the cable itself.
NOTICE: To prevent damage to the drives and backplane, you must disengage or remove the SCSI drives from the system before removing the
backplane.
NOTICE: If you completely remove the drives from the system, you must note the number of each drive and temporarily label them before removal, so
you can replace them in the same locations.
