• 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.

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.

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

).

For Quantum DAT removable tape drives, appropriate cables and 

terminators are provided with the tape array.

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