2.4 SCSI Bus Termination

Bus termination is required at each end of the SCSI bus. Typically, the SCSI bus

has the KZPSA adapter at one end and some storage device at the other end. In

this case, you must have termination resistor packs (Z1–Z5, Figure 2–1) installed

in the KZPSA adapter; these are installed at the factory. There should not be any

termination at any of the intermediate devices. If the KZPSA is used in the mid-

dle of the SCSI bus, the termination resistors should be removed from that

KZPSA.

NOTE

When connecting a "Y-cable" (BN21W-OB) to the

KZPSA, be sure to remove termination resistors

Z1–Z5 from the adapter. In this configuration, the

KZPSA is no longer at the end of the bus and ex-

ternal termination must be installed.
