Step 9. Installing the SCSI Bus Terminator
Make sure to install a terminator on the last device in the configuration.
To install the SCSI terminator, align it with the unused SCSI connector on
the 7207-122 Tape Drive and push in until the terminator is seated. Secure
the terminator with the thumbscrews.
If the 7207-122 Tape Drive (
.1/
in Figure 5) is the only SCSI device attached
to the RS/6000
.2/
, install the terminator
.3/
on one of the dual connectors
.4/
.
Figure 5. Example of Attaching One SCSI Device to the System Unit. The view is from the
side. The thumbscrews on the connector are not shown.
If there is more than one device (
.1/
in Figure 6) attached to the RS/6000
.2/
,
move the terminator
.3/
to the last device.

Notes:
1. The terminator and the SCSI bus cable can be connected to either the top or
bottom SCSI connector on the 7207-122 Tape Drive.
2. Only one external terminator is required to terminate the SCSI bus. You do not
need to use the terminator shipped with the 7207-122 Tape Drive if you already
have an IBM-approved terminator installed at the end of your SCSI bus.
3. If the 7207-122 Tape Drive is installed at the end of a narrow bus, do not use
the existing narrow terminator. Instead, use the 68-pin terminator that is
supplied with the device-to-device cable.
