vices. Use of other cables can result in signifi-
cant problems with system operation.
Narrow singled-ended SCSI definition limits the total cable length of
SCSI cables to 6 meters (19.6 feet).
Fast, wide differential SCSI definition limits the total cable length of
SCSI cables to 25 meters (82 feet).
Ultra, wide–SE SCSI definition limits the total cable length of SCSI
cables to 3 meters (9.84 feet).
Always use the shortest possible cable(s) for your configuration.
If you are daisy-chaining narrow single-ended 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 fast, wide differential SCSI devices togeth-
er, 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 following cables:
• C2978A cable with 0.5 meter (1.64 feet) length
NOTICE: See “Determining SCSI Bus Length” later in
this Appendix to determine the total length of
your cables.
