Figure 8 illustrates a typical synchronized spindle configuration.

After connecting each drive with spindle sync cables, you must designate a master spindle sync reference source. This master source is normally a disc drive located on the same SCSI bus as the other drives you want to synchronize with. To designate a drive as the master, use SCSI interface commands. Refer to the product manual for information about using these commands.
