Scsi Restrictions - HP Visualize j6000 Supplementary Manual

CAUTION A narrow SCSI device can not be placed between two wide devices.

SCSI Restrictions

This section describes the SCSI restrictions that apply to the J6000 workstations in the
following areas:
• Cables
• Terminators
• SCSI configuration constraint
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" 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.
