1. [. . . ] 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. 4.
Use needlenose pliers to remove the SCSI terminators, if still attached to the drive. 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. Figure NO TAG shows the available options.

Floppy Drive
The floppy disk drive ships with the drive set to SCSI ID address 0. We recommend keeping the address setting at 0 unless it is used by another device. CAUTION: Floppy disk drives are susceptible to mechanical and electrostatic shock. When handling the drive, always wear the static-grounding wrist strap that came in the floppy disk drive kit. If you need to change the floppy disk drive's address, follow these instructions, referring to Figures B12 and B13. If you do not need to change the drive's address, go to Step 10 of this installation procedure. To change the jumpers, use needlenose pliers to set the drive's SCSI ID to an address that is not used by another SCSI device. The host SCSI controller uses SCSI ID 7.

14. With the disk mounting bracket between the guides on each side
of the Storage Assembly, slide the disk into the Storage Assembly, securing it with the two side screws. Do not over-tighten the side screws.
Reconnect the drive SCSI and power cables here.

15. Reconnect the cabling from the back of the drive to the side of
the drawer assembly. Secure the EMI plate at the back of the removable drives with
the captive screw in the bottom of the plate.
17. Push the drawer ejector handle up until the Storage Assembly
slides all the way into the system unit and secure the two captive screws on the left of the Storage Assembly, as shown in Figure B16.
NOTICE:
If the ejector handle is not pushed completely in, you may not have proper seating of the SCSI PCB interconnect to the backplane.
