Figure 2.4 Changing the drive's termination
jumper block
Default configuration:
SCSI ID = 4, drive
terminated
3 Determine whether the tape drive should be terminated or unterminated.
The jumper marked T on the jumper block controls termination.
•
If the tape drive is the last device or the only device on the internal
SCSI bus and the computer's SCSI ribbon cable has no active
termination, the tape drive's termination jumper should remain in
place. (See figure 2.4.) Any other device between the SCSI controller
and the tape drive must not be terminated. Go to step 4.
•
If the tape drive is not the last device on the internal SCSI bus and/or
the computer's SCSI ribbon cable has active termination (a terminator
block on the end of the cable or an in-line terminator), you must
remove the termination jumper from the bottom of the tape drive, as
shown in figure 2.4.
4 If your computer requires special rails or other hardware to install the tape
drive, mount them on the tape drive in this step. Many computers require
no special mounting hardware, however. If other devices in your computer
are not mounted with special rails or tray, proceed with the next section,
"Installing the Tape Drive in the Bay" on page 2-9.


If you are installing the drive in an HP NetServer E-series or an HP
Vectra, attach the HP rails to the tape drive with the screws provided, as
shown in figure 2.5.


If your computer uses mounting hardware (either rails or a tray) and you
have a spare set, attach them to the tape drive as directed in your
