# Introduction

The PMC-8631 single-channel Ultra320 SCSI PMC card offers data transfer rates up to 320MB/s and achieves maximum transfer rates on a Wide SCSI bus (16-bit) with both Single-Ended (SE) and Low Voltage Differential (LVD) devices. The PMC-8631 is PCI Local Bus Specification, Revision 2.3; SCSI Parallel Interface-4 (SP1-4), Revision 10; and SCSI-3 standard compliant in addition to supporting multimode.

# 1.1 Features and Specifications

# PCI Interface Features

• Supports 66-MHz, 64-bit interface down to PCI-33MHz, 32-bit interface
Performance-enhanced 32-bit operating mode allows 32-bit data transactions with 32- and 64-bit addressing (SAC/DAC)
• Supports 3.3V power supply, 5V tolerance

# SCSI Features

• SCSI data transfers up to 320 MB/sec
• 8- or 16-bit SCSI data path
• SCSI data offsets to 254 transfers
Supports rear SCSI by JP1 jumper setting
• Advanced multimode I/O cell is compatible with LVD or SE devices
• Extensive hardware support for disconnect/reconnect and scatter/gather
• Full support for initiator operation
Full support for domain validation, which provides two levels (basic and enhanced) of SCSI bus configuration testing to help ensure Ultra320 and Ultra160 SCSI topologies operate at optimum speed
• Multiple target ID enables responses to multiple IDs as a SCSI target
Full support for Cyclic Redundancy Check (CRC) for 16-bit SCSI synchronous data transfers. CRC detects data integrity errors that would not be detected by simple parity checking used by previous SCSI generations. The higher data rates achieved on existing LVD cable configurations mandated this improved data integrity feature.
Supports Quick Arbitration and Selection (QAS) and SCSI arbitration fairness. QAS reduces overhead when bus control is transferred between devices. Arbitration fairness prevents devices from hogging the bus by guaranteeing each device a chance to win arbitration.
Supports Seamless Streaming technology, which allows full implementation of SCSI packet protocol for sending multiple commands, receiving multiple statuses, and transferring data for multiple commands during one SCSI connection. There is virtually no delay between packets for different commands.

# SCSI Device Support:

Using LVD devices, each channel supports up to 15 devices on a 12- meter cable. In a point-to-point arrangement, cabling can extend to 25 meters.
Support for a combination of 16-bit Ultra320, Ultra160 (Ultra3), Ultra2, Ultra, and standard SCSI devices including disk drives, disk arrays, tape drives, CDROM and CD-R drives, jukeboxes, removable drives, scanners, and printers.

# Getting Started

This chapter describes how to prepare the PMC-8631 for installation. Please carefully review the unpacking information before removing the product. The optional settings are also specified below.

# 2.1 What’s Included

In addition to this User's Manual, the package includes the following item:

• PMC-8631 Ultra320 SCSI Interface PMC Module

If anything is missing or damaged, contact the dealer the product was purchased. Save the shipping materials and carton to ship or store the product in the future.

# 2.2 Unpacking

The PMC-8631 card contains sensitive electronic components that can be easily damaged by static electricity.

Prepare a grounded anti-static mat. The operator should be wearing an antistatic wristband, grounded at the same point as the anti-static mat.

Inspect the card module carton for obvious damage. Shipping and handling may cause damage to the module. Be sure there is no obvious damage due to shipping and handing by examining the shipping box.

After opening the card module carton, extract the system module and place it only on a grounded anti-static surface, component side up.

Note: DO NOT APPLY POWER TO THE CARD IF IT HAS BEEN DAMAGED.

# Installation

# 3.1 PMC Board Installation

Insert the face of the PMC module into the front of the cPCI carrier board. Carefully align the PMC connector to the carrier board and firmly place it in the slot. Secure the module to the carrier board with the screws provided (see Figure 3.1 below).

![J21\nJ22\nJ23\nJ24\nJ11\nJ12\nJ13\nJ14\nSingle Width\nPMC Module](.pmc-8631-manual-1/c71dde28a1b1b6c9c2de5979c8cfe0b7bc664e3da304ca5b389ab03fddf6bb32.jpg)

Figure 3.1 PMC Module Installation
Note: Ensure that the PMC module(s) are properly installed before connecting the cPCI carrier board to the system.

# 3.2 Device Driver Installation

This section describes the installation procedure for the Adaptec AIC-7901X chipset device driver under Linux Redhat and Windows 2000, XP, and Server 2003.

The drivers are provided on the ADLINK All-in-One CD. Start your system and place the disk into the CD-ROM drive. The drivers are located in the X:\PMC\PMC-8631\ folder (where X:\ is the drive letter assigned to the CD-ROM drive). The operating system will detect new hardware and the Found New Hardware Wizard will appear. Navigate to the appropriate folder on the CD for your operating system and install the driver.

Fedora Core 1 and Core 2 are not officially supported for the PMC-8631. We have provided the Linux driver source code on the ADLINK All-in-One CD so customers can integrate it into their Fedora operating system.
