SCSI Connections
SCSI Restrictions
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.
The NSE SCSI definition limits the total cable length of NSE SCSI cables to
6 meters (19.6 feet).
The FWD SCSI definition limits the total cable length of FWD SCSI cables
to 25 meters (82 feet).
The ultra, wide-SE SCSI definition limits the total cable length of ultra,
wide-SE SCSI cables to 3 meters (9.84 feet).
Always use the shortest possible cable(s) for your configuration.
If you are daisy-chaining NSE SCSI devices together, use the following
cables:
•
92222A cable with 0.5 meter (1.6 feet) length
•
92222B cable with 1.0 meter (3.2 feet) length
•
92222C cable with 2.0 meter (6.6 feet) length
If you are daisy-chaining FWD SCSI devices together, use the following
cables:
•
C2911A cable with 0.9 meter (3 feet) length
•
C2924A cable with 2.5 meter (8.2 feet) length
•
C2925A cable with 10.0 meter (32.8 feet) length
•
C2926A cable with 20.0 meter (65.6 feet) length
If you are daisy-chaining ultra, wide-SE SCSI devices together, use the fol-
lowing cables:
•
C2978A cable with 0.5 meter (1.6 feet) length
•
C2979A cable with 1.5 meter (5 feet) length
NOTICE
See “Determining SCSI Bus Length” later in this Appendix to determine
the total length of your cables.
