The connection of the external SCSI devices isthrough an optional external SCSI-2 cable.NOTE: The number of SCSI devices that can beconnected to the external SCSI cable is dependenton the number of devices connected internally. Yoursystem supports up to seven SCSI devices, includ-ing both internal and external devices.Also, the maximum length of the external SCSI-2cable cannot exceed 19.68 feet (6 meters). If youare connecting SCSI devices to both the standardinternal SCSI cable and to the external SCSI-2 port,use the shortest external SCSI cable possible.Connect an external SCSI device after you install all yourinternal hardware options.NOTE: If you have internal SCSI devices, removethe termination from the last device on the internalSCSI cable.Use the following procedure to connect an external SCSIdevice to the system.1.
