Installing a Drive in the Floppy Bracket

Before you begin, refer to the documentation that came with your drive to determine how
to configure the drive. To install a drive in the lower position of the floppy bracket, refer
to Figure 4–10 and the procedure that follows.
Figure 4–10: Installing a Drive in the Floppy Bracket
1. Select a SCSI address and make sure SCSI termination is disabled. Terminator power
should be enabled. (Record the SCSI address you use in Appendix F, Equipment
Log.)
2. Orient the bracket, as Figure 4–10 shows. Position the drive so that the cable
connections face the rear of the system. Select the bracket mounting holes that match
the threaded holes in the drive. Mount the drive in the floppy bracket, securing it with
the four screws provided with the drive (two on each side).
3. Connect the power and SCSI cables to the drive before fully inserting and securing the
floppy bracket.
Verify that the cables are connected in the correct orientation. All cables and most
connectors are keyed so that you cannot connect them incorrectly. If your drive is not
keyed, you must connect pin 1 of the cable to pin 1 of the connector.
Pin 1 of the cable is on the edge with the colored stripe or pattern. Pin 1 of the
connector is marked with a small number "1" at one end of the connector or with a
small number "1" or "2" printed on the circuit board near one end of the connector.
4. Replace the floppy drive bracket assembly. Slide it forward until it locks in place.
5. Replace the cover.
6. Connect the power cord and plug it into the wall outlet.
