SCSI Connections
SCSI Restrictions
If you are daisy-chaining SE 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 FW 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
See "Determining SCSI Bus Length" later in this Appendix to determine
the total length of your cables.
Connectors and Terminators
Any SE SCSI device connecting to the system must use a 50-pin high-den-
sity thumb screw connector on the end connecting to the systems external
connector.
Any FW SCSI device connecting to the system must use a 68-pin high-den-
sity thumb screw connector on both ends.
If no external devices are connected to either SCSI connector on the
back panel, a SCSI terminator must be installed. The last device
connected to the SCSI bus must be terminated with a SCSI
terminator. All of the devices listed ship without terminators. If you
do not already have a SCSI terminator, you must order a C2905A,
68-pin terminator for the FW SCSI bus, or a C2904A, 50-pin high
density terminator for the SE SCSI bus from Hewlett-Packard.
