Installation Instructions: AM-3501 Expansion Subsystem Page 1 1.0INTRODUCTION This document describes the installation of both I/O and SCSI peripheral devices into the AM-3501 expansion subsystem. The AM-3501 is designed to be used with Alpha Micro computer systems containing an "I/O paddle card bus interface".

The dimensions, type of power supply, and method of installing peripheral devices is exactly the same as the Eagle computer. The front panel on the AM-3501 subsystem does not have (or require) an operational reset button or a digital display. The front panel does have a "power on" status light, which remains lit whenever the power is on.

Although it doesn’t seem like much, that tiny bolt of static electricity discharged through your finger tips has the power to degrade or ruin electronic components. Termination: Two SCSI connectors are present on the rear panel of the AM-3501 subsystem.

Page 6 Installation Instructions: AM-3501 Expansion Subsystem 5.0SCSI PERIPHERAL DEVICES - INSTALLATION AND CABLING Your subsystem cabinet can physically hold six half-height 5-1/4" peripherals, or three full-height 5-1/4" peripherals. Filler panels in the subsystem front panel can be removed to allow access to some of these peripherals.
PAGE 10
Installation Instructions: AM-3501 Expansion Subsystem Page 7 To install a peripheral device, simply slide it into one of the available mounting positions in your subsystem chassis and install the four screws (two on each side) that hold the device in place. In order to install peripheral devices in mounting positions 3, 4, 5, and 6, you will need to remove the side mounting plate as shown in the following illustration.

Page 8 Installation Instructions: AM-3501 Expansion Subsystem 6.0SERIAL I/O BOARDS - INSTALLATION AND CABLING The following sections describe how to install serial I/O boards into your AM-3501 subsystem. Depending on board types, you can install up to 7 serial I/O paddle cards into the subsystem. As previously noted, the B-channel subsystem expansion bus supports onlyserial I/O paddle cards.
PAGE 12
Installation Instructions: AM-3501 Expansion Subsystem Page 9 6.2Installing Serial I/O Boards All serial I/O paddle cards have factory installed mounting brackets. The following instructions explain how to install the paddle cards in the AM-3501 subsystem: 1.The serial boards attach directly inside rear panel and are held in place with three screws. To install a serial I/O board, you must first remove the filler panel covering the slot where you wish to install the board. 2.

Page 10 Installation Instructions: AM-3501 Expansion Subsystem 4.You must remove the termination resistor packs from all I/O boards except the last board on the expansion cable. 5.There is a 60-pin cable in your product installation kit that has seven 60-pin connectors. Start by plugging the cable into the INTERNAL (J4)connector on the AM-349 board. Make sure the colored stripe on the cable aligns with pin-1 on the AM-349’s J4 connector. 6.

Installation Instructions: AM-3501 Expansion Subsystem Page 11 8.0AM-3501 TO MAIN CPU EXTERNAL CABLING Due to the versatility of the AM-3501 subsystem and the numerous host configurations to which it may be attached, all externalcabling between the subsystem and the host computer must be ordered separately. This includes both the external SCSI cable, and the 60-pin SIO paddle card expansion bus cable. 8.

Page 12 Installation Instructions: AM-3501 Expansion Subsystem 1.Remove the rear panel mounting plate (DWF-20129-20) and the connector mounting receptacle (CNA-00079-10) from the shipping kit. Be sure to use the metricscrews provided with the connector! If you force a standard-thread screw into the embedded burl nut you will most likely break the nut loose from the plastic housing and will NOT be able to secure the connector to the mounting plate. 2.

APPENDIX A Peripheral Device Terminators and Termination Power A.1SCSI TERMINATION USING EXTERNAL TERMINATOR OPTION The preferred method of terminating the SCSI bus in an AMOS based computer is the installation of an external terminator. In Early April of 1993, the external SCSI bus terminator became standard on all AMOS based computer configurations.

External Terminator Installation Figure A-1 shows two different types of external SCSI connectors. Configuration"A" shows an extended external SCSI connector and bail locks for holding the terminator in place. This configuration is used on almost all of Alpha Micro’s currently available product.
PAGE 19
Peripheral Device Terminators and Termination Power Page A-3 A.2TERMINATION POWER In order to properly control SCSI bus termination, a termination power source must be provided; this is especially important when using an external terminator. Why is Termination Power so important when using an external terminator? In order for terminators to do their job, they must have a power source.
PAGE 20
Page A-4 Appendix A 3.If a computer with one or more SCSI peripherals is cabled to a subsystem with additional SCSI devices, the SCSI devices in the subsystem should be configured so they do not supply termination power. Ideally, you want the SCSI host controller in the main system to be the sole source of termination power. The termination power guidelines described above are valid even when you are using SCSI peripherals that do not support SCSI-2 protocol.
