10.2Cable Specifications

(1)SCSI Interface Cable

Use interface cables that meet the ANSI SCSI guideline.

The total cable length must be within the maximum cable length in case multiple drives are daisy chained. Specifications of maximum cable length are shown in Table 10.2 and Table 10.3.

The length of a cable connected between SCSI devices must be a minimum of 12 cm. (The stub length of the drive: 4 cm)

If an external cable the stub length of which becomes long is connected

to the devices, the cable length between the devices must be a minimum of (external stub length + 4 cm) x 3.

If data are transferred by Ultra SCSI (Fast-20) mode, Ultra2 SCSI (Fast-40) mode, Ultra160 SCSI (Fast-80) mode or Ultra320 SCSI (Fast-160) mode, check that the interface reflection noise does not influence the motion of the drive in the actual user’s system.
