Gathering Tools and Documentation

To install the drive, you need the following items:
v A flat-blade screwdriver
v Your system unit documentation, including any service documentation
v Your operating system documentation

Planning Your SCSI Device Layout

SCSI devices include such hardware as disk drives, tape drives, CD-ROM drives,
DVD-RAM drives, scanners, and printers. Some SCSI devices can be connected to or
installed inside your system unit, while others can be installed externally. The devices
are attached, in a daisy-chain configuration, to a SCSI adapter installed inside the
system unit.
Each device in the chain has a unique SCSI address (also called a SCSI ID). When
you connect more than one SCSI device, it is important that you plan the location and
address of each device in the chain. You must also be sure to connect a terminator at
each end of the chain. If you are using an internally connected device, the SCSI
adapter provides the termination for that end. The last attached device must terminate
the other end of the chain.
If your configuration includes both internal and external devices, you must connect a
terminator to the last external device and terminate the internal SCSI cable. The
adapter terminates one end of the chain, and the last device terminates the other end.

Determining Your SCSI Device Address

Before you install the 4.7GB SCSI-2 DVD-RAM Drive, you must set the SCSI address
on the drive. First, you must determine which SCSI addresses are available to use.
Then you choose an address and install jumpers on the drive to set the selected
address. You can use any available SCSI address as long as no two SCSI devices on
the same chain use the same address. No device can use address 7, which is reserved
for the SCSI adapter.
SCSI addresses are in sequential order from highest to lowest priority. Refer to Table 1
below for the priority associated with each SCSI address. For optimum performance,
choose the highest unused SCSI address between 6 and 0.
Note: Use only SCSI addresses 6 through 0 for this device.
