C-7
Connectors and Terminator
Any single-ended standard SCSI-2 device connecting to the system
board 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-2 de-
vice, the cable must have low-density connectors on each end.
Any fast, wide SCSI-3 device connecting to the system board must
use a 68-pin high-density thumb screw connector 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 connectors)
from Hewlett-Packard.
SCSI Configuration Constraints
You are limited to the number of same-type SCSI devices per system.
Before adding another SCSI device, determine if the system can sup-
port the additional device.
This workstation offers the following types of SCSI bus, each with its
own configuration constraints:
•
single-ended standard SCSI-2 bus
•
fast-wide, SCSI-3 bus
Single-Ended SCSI-2 Bus Configuration Constraints
For the single-ended standard SCSI-2 bus, HP-UX supports only one
of each type of removable disk drive and two of the same type tape
devices per system. Table C–3 shows configuration constraints for
each single-ended standard SCSI-2 device type. If the system has in-
ternal hard disk drives or a floppy disk drive, you must count them as
SCSI-2 devices.
