In addition, each supported cable comes in various lengths. Use the shortest possible cables to adhere to the limits on SCSI bus length.

Table 2–3 describes each supported cable and the context in which you would use the cable. Note that there are cables with the Compaq 6-3 part number that are not listed, but are equivalent to the cables listed.

aDo not use a KZPBA-CB with a DWZZA-AA or DWZZB-AA and a TZ885 or TZ887. The DWZZAs and DWZZBs can not operate at UltraSCSI speed.

Always check a SCSI cable for bent or broken pins. Be sure that you do not bend or break any pins when you connect or disconnect a cable.
