DDS Tape Drive
The DDS tape drive ships with the drive set to SCSI ID address
3 and the Operation Mode switches set for correct drive opera-
tion. We recommend keeping the address setting at 3 unless it is
used by another device.
CAUTION: SCSI tape drives are susceptible to mechanical
and electrostatic shock. When handling the drive,
always wear the static-grounding wrist strap that
came in the DDS tape drive kit. Always handle
the drive carefully.
If you need to change the DDS tape drive's address or operation
mode, follow these instructions, referring to Figure A–7 for the
DDS-DC drive, Figure A–8 for the DDS-2 drive, and Figure
A–9 for operation mode. If you do not need to change the drive's
address or operation mode, go to Step 10 of this installation pro-
cedure.
1. Locate the jumpers at the back of the DDS tape drive.
2. To change the jumper settings, use needlenose pliers to set
the drive's SCSI ID to an address that is not used by another
SCSI device. Check that the other jumpers are set correctly.
NOTICE: Do not use SCSI ID 7 for your DDS tape drive's
SCSI address. The host SCSI controller uses
SCSI ID 7.
3. Use needlenose pliers to remove the SCSI terminators, if
still attached to the drive.
4. If you need to change the Operation Mode switches, locate
the switches on the underside of the DDS tape drive.
Switches 1 and 2 are used to configure the data compression
operation mode. Switches 3 through 8 are used to specify
drive connectivity and functionality according to host or
customer requirements. The default setting is all switches
ON. Figure A–9 shows the available options.
