SCSI Restrictions
This section describes the SCSI restrictions that apply to the J6000 workstations in the following areas:
•Cables
•Terminators
•SCSI configuration constraints
NOTE The J6000 SCSI bus supports only 7 narrow SCSI devices because address 7 is reserved by the system. Similarly, the SCSI bus supports only 15 wide SCSI devices because address 7 is reserved by the system.
Cables
Only SCSI cables approved by HP can be used to connect a J6000 workstation to SCSI devices. HP offers the following SCSI cables for SE SCSI devices:
•1.0 meter (3.281 feet) cable (HP Product Number C2908A)
•1.5 meter (4.922 feet) cable (HP Product Number C2956A) HP offers the following SCSI cables for LVD SCSI devices:
•0.5 meter (1.64 feet) cable (HP Product Number C2978A)
•1.5 meter (4.922 feet) cable (HP Product Number C2979A)
CAUTION SCSI cables approved by HP are designed to function within the SCSI tolerances for HP devices. Use of other cables can result in significant problems with system operation.
Always use the shortest possible cable(s) for a configuration.
NOTE | See “SCSI Bus Length Constraints” on page 138 to determine the total length |
| of SCSI cables. |

Terminators
The J6000 workstation has auto termination and does not require external termination.
NOTE | The last external device connected to the SCSI bus must be terminated with a |
| SCSI terminator. |
