SCSI Cables

Cable Quality 2

• It is important to use good quality cables. Generally speaking, cable

quality affects performance and reliability. This is particularly true

for external, shielded cables.

• Look after your SCSI cables. In particular, take care when connecting

or disconnecting not to damage the high-density connectors. Avoid

putting excessive twists in external shielded cables, as this can cause

premature failure.

With Internal Devices

For Quantum DAT internal devices, you need a SCSI ribbon cable with

the correct termination. The drives have a 68-pin wide, high-density SCSI

connector. If you are using an Quantum DAT drive on an internal bus

with other peripherals that run at Ultra160 speeds, it is important that a

68-pin LVD-compatible ribbon cable is used. Do not connect your tape

drive to lower-rated SCSI or to narrow SCSI.

With External Devices

The cable provided with all Quantum DAT external tape drives and

autoloaders will attach to a computer with a wide, very high density

(VHD), LVDS SCSI connector.

If your server or host bus adapter is equipped with a high density (HD)

wide SCSI connector, you will need to order a 68-pin VHD-to-HD

converter or 68-pin VHD-to-HD cable (see www.quantum.com/

ServiceandSupport/Index.aspx).

With Removable Devices

For Quantum DAT removable tape drives, appropriate cables and

terminators are provided with the tape array.

Note on SE and LVD

Interfaces

SE and LVD define how the signals are transmitted along the cable.
