C-8
Connectors and Terminator
Any narrow, single-ended SCSI device connecting to the system box
must use a 50-pin high-density thumb screw connector on the end
connecting to the system board, and a 50-pin low-density bail lock
connector on the other end. If you attach a second SCSI device, the
cable must have low-density connectors on each end.
Any fast, wide differential or ultra, wide–SE SCSI device connecting
to the system box must use a 68-pin high-density thumb screw con-
nector on both ends.
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 terminator
K2291 (for 50-pin connectors) or C2905A (for 68-pin fast, wide dif-
ferential connectors) or C2972A (for 68-pin ultra, wide–SE connec-
tors) from Hewlett-Packard.
SCSI Configuration Constraints
You are limited to a certain number of same-type SCSI devices per
system. Before adding another SCSI device, determine if the system
can support the additional device.
This workstation offers the following types of SCSI bus, each with its
own configuration constraints:
narrow, single-ended SCSI bus
fast-wide, differential SCSI bus (J282 or J2240 upgrade)
ultra, wide–single–ended, SCSI bus (J2240 only)
Narrow, Single-Ended SCSI Bus Configuration Constraints
For the narrow, single-ended SCSI bus, HP-UX supports only one of
each type of removable disk drive and two of the same type tape de-
