1 Product Description This chapter provides a product description of the KZPSA PCI-to-SCSI Storage Adapter. It also lists the operating standards for the adapter and its electrical and environmental specifications. 1.1 Introduction The KZPSA adapter (Figure 1–1) is a Peripheral Component Interconnect (PCI) to Small Computer System Interface-2 (SCSI-2) adapter. You install the adapter on your computer motherboard through a PCI connector for 32 bit/+5V operation.
KZPSA PCI-to-SCSI Storage Adapter The adapter’s processor minimizes the SCSI I/O overhead of the host computer’s processor by interpreting host commands and translating them into specific device commands. This includes support for direct data transfer to host memory, coding device-specific commands into specific command scripts, and supporting internal command queues with disconnect/reconnect functionality.
Chapter 1.
KZPSA PCI-to-SCSI Storage Adapter 1.2 Standards The KZPSA adapter conforms to the Standards listed in Table 1–1. Table 1–1 Standards Industry Standard 1.3 Description SCSI-2 ANSI X3T9.2/86-109 - SCSI Specification. PCI PCI Local Bus Specification Rev 2.0. FCC Class B Residential use. Specifications The electrical and environmental specifications for the KZPSA adapter are listed in Table 1–2.
2 Configuration Guidelines Before you install the KZPSA PCI-to-SCSI storage adapter in your computer, you need to become familiar with the configuration guidelines for the host adapter and its SCSI bus. This chapter will help you plan your system configuration. It discusses the SCSI bus configuration, bus termination and power, and describes bus signals and their functions. 2.
KZPSA PCI-to-SCSI Storage Adapter These defaults were chosen for optimum performance of the adapter. If they are acceptable for your configuration, proceed to Installation in Chapter 3. Each of these attributes, except for termination present, can be changed by using the configuration utility described in Chapter 6. 2.2 PCI Bus Configuration PCI Adapters are automatically configured by the power-up software. The adapter addresses and interrupts are set without jumpers. 2.
Chapter 2. Configuration Guidelines 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.
KZPSA PCI-to-SCSI Storage Adapter 2.5 SCSI Termination Power It is normal for adapters, not devices, to supply termination power to the SCSI bus. The KZPSA adapter is configured at the factory to supply 1.5 amps of termination current. Although each SCSI node may supply termination power to the bus, a single source from the host adapter is sufficient. No more than four sources of termination power on a SCSI bus is recommended. 2.
Chapter 2. Configuration Guidelines 2.11 Device Disconnects To optimize overall SCSI bus performance, the adapter default allows device disconnects. This means that a device that realizes a need for a lengthy delay before the next data can be transferred can disconnect this operation to allow another device to utilize the bus, and resume it later when the data is available. This disconnect may also be disabled when there is only a single device on the bus.
3 Installing the KZPSA Adapter This chapter describes how to install the KZPSA adapter board into a computer. 3.1 Unpacking Unpack the KZPSA PCI-to-SCSI Storage Adapter kit and place the contents (board, diskettes, etc.) in an area where they are protected and accessible for installation. Perform an inventory of the contents.
KZPSA PCI-to-SCSI Storage Adapter 3.2 Hardware Installation Procedure CAUTION Static electricity can destroy the circuits on the KZPSA adapter. Discharge static electricity by touching the system box's metal frame before handling the KZPSA module or any other modules. 1. Power down your computer and remove the covers to access the motherboard. Refer to your host system manual for general instructions on installing adapters.
