Before you connect the optical drive option, observe the following
precautions.
Be sure that power to the host computer and to the drive is off.
Verify that the SCSI bus is inactive before disconnecting power to any
device on the bus.
Remove inserted disks before moving the drive.
Follow these steps to connect the drive option. See your optical drive
manual for location of the switches. See

Use a small screwdriver or pen point to set the SCSI switch on the
optical drive to 1.

the drive to 1.
NOTE: If you change the SCSI ID or operation mode at a later date, power
cycle the drive so that the host recognizes the change.

peripheral on a daisy-chain.
NOTE: The length of the SCSI cable cannot exceed 6 meters, including the
internal cable length of all peripherals on the SCSI bus. The optical drive
internal cable length is 0.3 meters.

Plug one end of the power cord into the AC connector on the rear of the
drive; plug the other end of the cable into an AC power outlet.
