  • Page 5: Introduction

    Alpha Micro Dealer or the Alpha Micro Technical Support Group for help. Installing a SCSI disk drive is simply a matter of placing the drive inside your computer chassis, connecting the appropriate power and interface cables, and configuring the correct software.

  • Page 6: Tools Required

    4.0HANDLING SCSI DISK DRIVES Disk drives can be damaged easily when handled improperly: 1.Leave the SCSI drive in the anti-static bag it was shipped in until you are ready to install it. 2.Never handle a disk drive unless you are properly grounded. This will prevent a static charge from damaging the drive before you even have it installed.

  • Page 7: Scsi Termination Using External Terminator Option

    Page 3 6.0SCSI 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. Using an...

  • Page 8: Termination Procedure (Without External Terminator)

    CPU board must be terminated. 3.If an AM-14XX, AM-16XX, or pedestal computer includes a SCSI magnetic tape drive as its only SCSI device, the tape drive must have its terminators installed. 4.For AM-990, 10-slot rack mount VME, and 21-slot rack mount VME computers, the last SCSI device attached to the connector farthest down the cable away from the CPU board must have its terminators installed.

  • Page 9: Terminator Power

    The other disk or tape SCSI devices will be configured so they do not supply termination power. 3.If a computer does not have a SCSI disk drive, but does have one or more SCSI magnetic tape or CD-ROM drives, then one of these devices will be configured to supply termination power.

  • Page 12 Page 8 Installation Instructions: SCSI Disk Drives When ordered as independent demand, the PRF-00113-00 and (-20) mounting brackets are shipped unassembled. For most applications the 5-1/4" front bezel is not required. If your application does not require a front bezel, all you need to do is attach the rails to the drive as shown in Figure 4.
  • Page 13 Installation Instructions: SCSI Disk Drives Page 9 A 3-1/2" SCSI drive is installed in the bracket as shown in Figure 4. The drive is held in place with four screws, two in each side. The illustration shows the drive being mounted in the DWB-00113-10 bracket, but the procedure is virtually the same for all mounting brackets.

  • Page 14: 3-1/2" Scsi Drives In Series 90 Computers

    Series 90 computers also require 5-1/4" mounting brackets in order to mount 3-1/2" SCSI disk drives. For Series 90 AM-940, AM-980, and AM-990 computers, the drive is installed in the bracket as previously described, but the addition of two plastic mounting rails is required to be Series 90 compatible.

  • Page 15: Isolating Signal And Chassis Grounds

    For all AMOS 680X0 applications it is important to prevent the disk drive’s DC (signal) ground from being shorted to the computer’s AC (chassis) ground. Alpha Micro’s SCSI drive mounting kits contain the necessary hardware used to isolate the drive from chassis ground.
  • Page 16 Page 12 Installation Instructions: SCSI Disk Drives Checking Individual Peripherals for Shorts to Chassis Ground 1.To determine if a peripheral is shorted to chassis ground, disconnect the peripheral’s power and interface cables, but do not loosen or remove any of the peripheral’s mounting hardware. Use an ohm meter to measure between chassis ground and either of the two middle pins on the peripheral’s power connector.

Unlike most of the other applications, no 5-1/4" mounting bracket is required for AM-1400/1600 computers.

  • Page 19: Drive Isolation (Am-990 Universal Vme Enclosure)

    For AM-990 installations, no special drive isolation steps need to be taken. 11.0FORMATTING YOUR SCSI DISK DRIVE All SCSI drives shipped by Alpha Micro are formatted and ready for use, providing you are using an Alpha Micro computer running AMOS. If you are installing a SCSI disk drive into a Series 90 computer, you will need to format the drive before it can be used.
  • Page 20 Page 16 Installation Instructions: SCSI Disk Drives Under AMOS 2.2 (or later) operating systems, you can divide your hard disk drive into logical splits larger than 32MB. In fact, you could take a 540MB drive and make it one giant 540MB logical. While this is perfectly acceptable, you may get a memory allocation error when running programs that load a copy of the bitmap into your memory partition—e.g., DSKANA and MONTST.
