Replacing the Computer Tape Drive

1. Turn the computer power switch OFF and unplug the power cord.
2. Remove the computer cover (see Figure 5-15).
3. Depress the latches on each side of the floppy drive (Figure 5-28) and slide the floppy
drive half way out of the top shelf. Make a written note of the orientation of the cable
connectors, unplug them and remove the floppy drive.
4. Repeat step 3 for the old tape drive and remove it. Note the cable connector orientation
before unplugging!
5. Unpack the new replacement tape drive, handling it carefully by its edges. Save all pack-
ing materials for use in returning the old unit.
6. Remove the side rails from the old tape drive and install them on the new replacement
drive, in the original orientation.
For Archive Viper and Cipher 150mb Tape Drives:
a. If the drive is used with a SCSI hard drive, remove the terminating resistors and
connect the drive to the middle connector of the SCSI cable. The terminating
resistors are in SIP form, located between the 50-pin SCSI connector and the
circuit board at the rear of the drive.
b. If the drive is to be used without a SCSI hard drive, install the terminating
resistors and connect the drive to the end of the SCSI cable.
NOTE: Be sure the red line on the 50-pin connector is closest to the power connector.
