160 MB SCSI Tape Cartridge (250-4166A) Install Faxback Doc. # 4997 BEFORE YOU BEGIN CAUTION: Static electricity can damage electronic components. To prevent discharge of static electricity into your computer equipment, touch a grounded metal object before touching the drive or computer. Before you begin, be sure your kit contains the tape drive, four rubber grommets, four shoulder screws, the SY-TOS tape operating system diskettes, and its manual. INSTALLATION The host adapter board can block access to the drive tower mounting screws. Install the tape drive (and any other internal SCSI drive) before you install the host adapter board. NOTE: You might need to remove other installed adapter boards that block access to the drive tower screws. INSTALLING THE TAPE DRIVE This manual assumes that you are installing the tape drive inside a computer that has an internal SCSI hard disk drive and at least one floppy diskette drive. (External installations of this drive will vary. See the instructions that come with your external drive kit.) The procedure for installing the tape drive depends on whether your computer has a Type A, Type B, or Type C chassis. Remove the computer cover as illustrated in your computer's user's guide. Then, compare your computer to the following illustrations to determine the chassis type. INSTALLATION IN A TYPE A CHASSIS To install the tape drive in a Type A chassis, slide the unit into the 5 1/4" drive bay and secure it with the supplied mounting screws, as shown. NOTE: You can only install one 5 1/4" device in a Type A chassis. INSTALLATION IN A TYPE B CHASSIS Install the tape drive in the unused 5 1/4" drive bay 1. Remove the appropriate drive rails (upper or lower set) from the drive tower. 2. Using the four machine screws supplied with the computer, attach the drive rails and metal grounding clips to the tape drive as shown. 3. Slide the tape drive into the drive bay until the rails lock into place. INSTALLATION IN A TYPE C CHASSIS There are two 5 1/4" drive bays in a Type C chassis. If you want to install the tape drive in the bottom 5 1/4" drive bay, you must remove the drive tower. (Removing the drive tower is not necessary for mounting the tape drive in the upper 5 1/4" drive bay.) Before installing the tape drive in a Type C chassis, not the location of any cables attached to the existing drives and disconnect the cables. Type C, Lower 5 1/4" Drive--Follow these steps to install the tape drive in the lower drive bay. 1. Detach the backup battery from the side of the drive tower. 2. Remove the four screws that secure the tower to the bottom of the computer chassis and the three screws that secure the tower to the front of the chassis. NOTE: Some computers with this type of drive tower do not have a front cover opening for the lower bay. In such computers, you must mount the tape drive in the upper bay. CAUTIONS: * The computer chassis' sharp edges can damage furniture and snag clothing. * Be careful not to let the computer fall while you remove the bottom screws. 3. Carefully lift the drive tower up and out of the chassis. 4. Attach two shock isolators to each side of the tape drive. 5. Slide the tape drive into the lower 5 1/4" drive bay. Do not let the tape drive touch any device installed in the upper drive bay. 6. Use the four supplied machine screws to fasten the unit to the drive tower. (Install one of the rubber washers on each screw before you insert it into the drive tower.) 7. Re-install the drive tower. Be sure that no cables are under the drive tower when you replace it. Re-attach the backup battery to the hook-and-loop strip on the side of the drive tower. (Velcro) 8. Reconnect any cables you removed from the existing drives. Type C, Upper 5 1/4" Drive--Follow these steps to install the tape drive in the upper drive bay. 1. Insert the four grommets that come with the Tape Cassette System into the mounting holes in the upper 5 1/4" drive bay. 2. Slide the tape drive into the upper drive bay. Be sure it does not touch any other installed devices. Use the four supplied machine screws to fasten the unit to the drive tower. 3. Reconnect any cables you removed from the existing drives. INSTALLING THE HOST ADAPTER BOARD After you install the tape drive in a drive bay, install the host adapter board and set its jumpers for proper operation. Refer to the instructions supplied with the host adapter board for more information. Select an empty, full-size option slot to install the board. It is usually necessary to install the board in the option slot closest to the drive tower so the data cable can reach it easily. CONNECTIONS The following steps describe how to connect the data and power cables to the tape drive. 1. Connect the single-connector end of the data cable to connector J2 on the host adapter board. Be sure to align the arrow on the cable with Pin 1 on the connector. 2. Attach the two-connector end of the data cable to the tape drive. NOTE: If you need to route the data cable between two boards, fold the cable so its flat side is parallel to the board width. Fold the cable again at the top of the board. 3. Connect an unused 4-pin power cable to the tape drive. 4. Reinstall the computer's cover. (dkh/jej-05/12/94)
