CHAPTER 4: Installing Your Tape Drive
4.3.2 Configuring the Internal Drive for TERMPWR
A SCSI bus must be terminated at each end of the bus. All signals not defined as
RESERVED, GROUND, or TERMPWR shall be terminated exactly once at each
end of the bus. At least one device must supply terminator power (TERMPWR).
To enable TERMPWR, install the jumper across Pins 1 and 2 ( Figure 4-3 ) on the
TERMPWR jumper block. Remove the jumper to disable TERMPWR. Pins 3 and
4 on this block are reserved and require no jumpering.
Figure 4-3.

4.3.3 Configuring the Internal Drive for Narrow SCSI
The 8-pin Configuration Jumper block allows you to enable or disable the wide
SCSI bus. The default setting is for the wide SCSI bus to be enabled; there is no
jumper across Pins 1 and 2 when wide SCSI is enabled (
Figure 4-1 on page 4-8 ).
To disable wide SCSI, install a jumper across Pins 1 and 2. Pins 3 through 8 are
reserved and require no jumpering.
4.3.4 Installing the Internal Tape Drive
Installing the tape drive requires securing the drive in its bay or chassis and
connecting SCSI bus and power cables, as described in
“Securing the Internal Tape
Drive” below. When you have finished mounting and installing the drive, proceed
directly to “Confirming the Installation” on page 4-23 to confirm the installation.
Two perspective views of the internal tape drive are shown in Figure 4-4 .
