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
NOTICE 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 system board.
Any FW SCSI device connecting to the system must use a 68-pin high-den-
sity thumb screw connector on both ends.
It is necessary to put a terminator on empty SCSI connectors on the back
panel of the system. Also, a SCSI device attached to the SCSI bus or the last
external device connected to the SCSI bus must be terminated with a SCSI
terminator. If you do not already have a SCSI terminator, you must order ter-
minator C2904A (for 50-pin connectors) or C2905A (for 68-pin connectors)
from Hewlett-Packard.
