SCSI Restrictions
This section describes the SCSI restrictions that apply to the J5000 and J7000
workstations in the following areas:
•
Cables
•
Terminators
•
SCSI configuration constraints
NOTE
The NSE 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 J5000 or J7000 workstation to
SCSI devices. HP offers the following SCSI cables for NSE 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 194 to determine the total length
of SCSI cables.
