Table 9–2: Installing the KZPSA-BB or KZPBA-CB for Radial Connection
to a DWZZH UltraSCSI Hub
Step
Action Refer to:
1
Ensure that the KZPSA-BB internal termination
resistors, Z1, Z2, Z3, Z4, and Z5 are installed.
Section 9.1.4.4,
Figure 9–1, and
KZPSA
PCI-to-SCSI Storage
Adapter Installation
and User’s Guide
Ensure that the eight KZPBA-CB internal
termination resistor SIPs, RM1-RM8 are installed.

2
Power down the system. Install a KZPSA-BB
PCI-to-SCSI 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 is within limits for the
system, and that the placement is acceptable.

Install a BN38C or BN38D cable between
the KZPSA-BB or KZPBA-CB UltraSCSI host
adapter and a DWZZH port.

_____________________ Notes _____________________
The maximum length of a SCSI bus segment is 25 meters (82 feet),
including the bus length internal to the adapter and storage devices.
One end of the BN38C cable is 68-pin high density. The other end is
68-pin VHDCI. The DWZZH accepts the 68-pin VHDCI connector.
The number of member systems on the shared SCSI bus has to be one
less than the number of DWZZH ports.
You may use a BN38E-0B technology adapter cable and a BN37A cable
in place of the BN38C cable.

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.
Firmware release
notes for the system
(Section 4.2) and
Section 9.1.4.5
______________________ 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.
