Product Description
This chapter gives a functional and physical overview of the KZPCM PCI-to-Dual
Channel Ultra SCSI and 10/100MB Ethernet Host Adapter (‘the KZPCM Host Adapter’ or
‘the Host Adapter’) and provides specifications for significant characteristics.
1.1 Functional Description
The KZPCM Host Adapter (Figure 1-1) provides an interface between a host
computer PCI bus and both internal and external SCSI devices. In addition, the
Host Adapter includes support for 10/100 Base-T Ethernet communications,
which can be carried on concurrently with I/O operations.

KZPCM PCI–to–Dual Channel Ultra SCSI and 10/100MB Ethernet Host Adapter
1–2 EK–KZPCM–UG. B01
The KZPCM Host Adapter is a leading edge host adapter that supports bootable
devices and provides a powerful multi-tasking interface. Each channel on the
Host Adapter forms a separate SCSI bus together with its attached devices. The
SCSI buses can be connected to disk drives, CD-ROM drives, tape drives, and
other SCSI devices. More than one Host Adapter can be installed in the same
host computer.
The SCSI processor negotiates with each device on the SCSI bus to establish the
data transfer rate between the host adapter and the device. It also automates
SCSI command processing and significantly reduces the number of interrupts and
command overhead.
The Host Adapter supports multi-threaded I/O operations, thereby allowing
simultaneous operations on multiple SCSI targets or Logical Units (LUNs). In
systems with multiple targets, the Disconnect/Reconnect feature optimizes SCSI
bus usage. In systems that support fragmented memory buffers, the
Scatter/Gather feature provides high performance.
1.2 Physical Description
The KZPCM Host Adapter components are mounted on a 4 ¼ inch by 8 ¾ inch
PCB that is inserted in a PCI expansion slot in the host computer motherboard.
The PCB has separate connectors for each of the two available Ultra SCSI
channels. Channel A has two 68-pin connectors for Ultra-wide SCSI operation,
one for external devices and one for internal devices, and one 50-pin connector
for Ultra-narrow internal SCSI devices; channel B has two 68-pin connectors for
Ultra-wide SCSI operation, one for external devices and one for internal devices.
External connection to an Ethernet network is made through a shielded RJ45
connector for 8-conductor twisted pair cable.
Channel A and Channel B are equipped with both internal and external ultra-
SCSI wide (supports 15 devices) connectors; in addition, Channel A is equipped
with an internal ultra-narrow 50-pin connector. However, a DIGITAL
StorageWorks shelf with ultra-wide connections can run ultra-wide and ultra-
narrow drives concurrently.
The external bulkhead of the Host Adapter contains LED indicators that monitor
Ethernet activity.

Installing the KZPCM Host Adapter
This chapter tells you how to terminate the SCSI buses, how to set SCSI IDs, how to
install the Host Adapter in your computer, and how to connect internal and external SCSI
devices to the adapter.
2.1 Installation Overview
The installation of the KZPCM Host Adapter consists of the following steps:
• Terminating the SCSI buses.
• Installing the Host Adapter module in your computer.
• Connecting internal or external SCSI devices to the adapter.
2.2 Getting Started
Before starting the installation, do the following:
• Check that you have the necessary user-supplied hardware and software
(refer to Subsection 2.2.1).
• Inventory the contents of the KZPCM Host Adapter kit
• Back up the computer system
2.2.1 User-Supplied Hardware and Software Requirements
The KZPCM Host Adapter requires the following user-supplied hardware and
software:
• An AXP- or Intel-based computer system with a PCI local bus, a 3½-inch
(1.44 MB) floppy drive, an available PCI slot, disk space to load software
drivers, and the associated system hardware manual
• The SCSI cables necessary to connect SCSI devices to the adapter module
• One of the following operating systems:
− Windows NT, version 4.0 or higher
− DIGITAL OpenVMS, version 7.1-1H1 or higher
− DIGITAL UNIX, version 4.0d or higher
• Alpha firmware upgrade CD5.0.

2.2.2 KZPCM Host Adapter Kit Contents
The KZPCM Host Adapter kit contains the following:
• KZPCM PCI-to-Ultra SCSI Host Adapter module
• License Agreement
• This guide
• Release Notes
• DIGITAL UNIX 4.0d KZPCM driver floppy disk
• DIGITAL OpenVMS 7.1-1H1 and 7.1-1H2 KZPCM driver floppy disk
• Windows NT 4.0 KZPCM driver floppy disk
Contact your Service Representative if any items are missing.
2.2.3 Back up Your System
Follow your normal procedures to back up your system before installing the
KZPCM Host Adapter.
2.3 Terminating the SCSI Buses
The KZPCM Host Adapter has dual-SCSI channel capability, and each bus must
be terminated at both ends of the bus. The Host Adapter can be located at the
beginning of the bus or in the middle of the bus; consequently, termination on
the Host Adapter itself can be enabled or disabled. Furthermore, if both the
wide- and narrow-SCSI connectors on the A-channel are used, the narrow-SCSI
termination on the Host Adapter must be disabled.
Use the termination switchpack, SW1, on the Host Adapter PCB (Figure 2-1) to
enable or disable terminations on the PCB. Tables 2-1 and 2-2 show how the
switchpack switches should be set according to how devices are connected to
Channel A and Channel B connectors, respectively, of the Host Adapter.
