SCSI Restrictions
This section describes the SCSI restrictions that apply to the J6700 workstations in the
following areas:
• Cables
• Terminators
• SCSI configuration constraints
NOTE
The SE SCSI bus supports only 7 devices because address 7 is reserved by the
system. Similarly, the LVD SCSI bus supports only 15 devices because
address 7 is reserved by the system.
Cables
Only SCSI cables approved by HP can be used to connect a J6700 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 146 to determine the total length
of SCSI cables.
Terminators
The J6700 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.
