Scsi Termination - Compaq Smart Array 221 User Manual

Available SCSI Cables for Compaq Servers
Server
ProLiant 6500
ProLiant 7000 - Pentium Pro
NOTE: All internal cables ship with servers. The ProSignia 200 does not ship with internal cables, but internal cable
option kits may be ordered if using a SCSI Controller.
More information about SCSI cabling can be found:
in the Setup and Installation Guide, or Reference Guide that
accompanied your server, or
at www.compaq.com, searching for "SCSI cable guidelines."

SCSI Termination

All SCSI buses require termination on both ends of the bus to prevent signal
degradation. The Smart Array 221 Controller supplies the termination on the
origination end of the SCSI bus. All internal SCSI cabling recommended for
Compaq servers provides the necessary termination for the opposite end of the
bus. Therefore, individual SCSI drives in Compaq servers should not contain
bus termination.
External SCSI devices must also provide termination for the SCSI bus. This is
supplied in Compaq ProLiant Storage Systems/U. Therefore, individual SCSI
drives in Compaq storage systems should not contain bus termination.
