Preparing The Tape Drive For The Scsi Bus - Exabyte EXB-8205 Installation And Operation Manual

Preparing the Tape Drive for the SCSI Bus

The SCSI bus that you attach the tape drive to must be
terminated correctly to ensure proper operation. The devices
that are physically located at each end of the SCSI cable must
have terminators installed. All other devices on the SCSI
cable must not have terminators installed.
If you place the tape drive at the end of the SCSI bus, you
must terminate the tape drive. The procedure you use
depends on whether the tape drive uses a single-ended or a
differential SCSI configuration.
Termination for a Single-Ended tape drive
The single-ended tape drive includes three single in-line
package (SIP) resistor terminators (R-packs) that can be left
in place if the tape drive terminates the SCSI bus.
The R-packs must be removed if the tape drive does
not terminate the SCSI bus or if external SCSI bus
termination will be used. Instructions for removing
the R-packs are provided below.
Optional External Termination
If desired, you can terminate the single-ended tape drive
externally by removing the R-packs from the back of the
tape drive and installing an external terminator. Exabyte
recommends a Methode Electronics, Inc. dataMate
DM103-02-0 single-ended external terminator.
Removing the R-Packs
To remove the R-packs, follow these steps:

Locate the three R-packs on the back of the tape
drive, as shown in Figure 3.
Using a pair of flat-nose wiring pliers, grasp each
R-pack in the center and pull it straight out. Be
careful not to squeeze the pliers too tightly or you
may break the R-pack.
