right, or vertical with the LEDs up.
The drive occupies a half-size 5.25-inch slot with standard holes for mounting

screws on both sides of the drive chassis and at the bottom of the drive.

Figure 1 Mounting specifications

Important!
Mounting screw

requirements

• Only M3 (metric) screws must be used for mounting the drive

• Maximum permitted screw penetration: 3.0 mm

• Minimum required screw penetration: 2.0 mm

SCSI Identification

Make sure that the drive unit has the proper SCSI-ID before it is connected to a
computer system.

Refer to manuals for host computer and application software to obtain the correct
ID. For correct mounting of ID-jumpers at the rear of the drive, please refer to
Figure 3 and Table 1.

External drives have a thumb-wheel switch to set the SCSI-ID (see Figure 6).

Power Connector

Figure 3 Drive connectors

The factory default drive
number setting is SCSI ID = 2.
If the drive has to be set up
with a different unit number,
the straps (on the Service
Connector) have to be
connected according to
Table 1.

Example: SCSI ID = 3

Termination

The SCSI-bus cable must be terminated in both ends according to SCSI
specifications. If the tape drive is the last device on the bus, the bus must be
terminated within 10 cm of the tape drive connection.

Tandberg 420LTO has a combined SCSI-LVD/SE interface embedded. The PC-98
Specification specifies that the termination of the SCSI-bus system is a part of the
SCSI-cable and not a part of the SCSI-device.

As a result, termination cannot be turned on or off directly on the tape drive itself.
For internal devices, a SCSI-cable with an integrated terminator or a separate
terminator applied to the end connector of the cable, 10 cm from the last device,
must be used.

External devices must be terminated with an external terminator on the last device
on the SCSI-bus.
