SCSI Connections

SCSI Restrictions

 

Connectors and Terminators

 

Any narrow, SE SCSI device connecting to the system must use a 50-pin

 

high-density thumb screw connector on the end connecting to the system

 

board.

 

Any fast, wide differential or ultra, wide-SE SCSI device connecting to the

 

system must use a 68-pin high-density thumb screw connector on both ends.

 

 

NOTICE

The terminators for fast, wide differential SCSI and ultra, wide-SE SCSI

 

are different and not compatible, even though the connectors are identical.

 

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 fast, wide

 

differential connectors) or C2972A (for 68-pin ultra, wide-SE connectors)

 

from Hewlett-Packard.
