Termination
Step
Action Refer to:
1
Remove the KZPSA-BB internal termination
resistors, Z1, Z2, Z3, Z4, and Z5.

2
Power down the member system. Install
a KZPSA-BB PCI-to-SCSI bus adapter or
KZPBA-CB UltraSCSI host adapter in the PCI
slot corresponding to the logical bus to be used for
the shared SCSI bus. Ensure that the number
of adapters are within limits for the system,
and that the placement is acceptable.

Install a BN21W-0B Y cable on each KZPSA-BB
or KZPBA-CB host adapter.

4
Install an H879-AA terminator on one leg of the
BN21W-0B Y cable of the member system that
will be on the end of the shared SCSI bus.

5
Power up the system, and update the system
SRM console firmware and KZPSA-BB host
bus adapter firmware from the latest Alpha
Systems Firmware Update CD-ROM.

notes for the system
(Section 4.2) and
Section 10.1.4.5
______________________ Note ______________________
The SRM console firmware includes the ISP1020/1040-based PCI
option firmware, which includes the KZPBA-CB. When you update the
SRM console firmware, you are enabling the KZPBA-CB firmware to
be updated. On a powerup reset, the SRM console loads KZPBA-CB
adapter firmware from the console system flash ROM into NVRAM for
all Qlogic ISP1020/1040-based PCI options, including the KZPBA-CB
PCI-to-Ultra SCSI adapter.
6
Use the show config and show device console
commands to display the installed devices
and information about the KZPSA-BBs or
KZPBA-CBs on the AlphaServer systems. Look
for KZPSA or pk* in the display to determine
which devices are KZPSA-BBs. Look for QLogic
ISP1020 in the show config display and
isp in the show device display to determine
which devices are KZPBA-CBs.
