STEP 1: Halting the System
If you are installing an internal DVD-RW or adding an external DVD-RW to a SCSI channel that already has
devices on the system bus, you must shutdown the system. If you are adding an external unit to a new, empty
channel you do not need to shut down and may continue to step 3. Before halting your system find out what
operating system you are running by typing:
# /usr/bin/uname -sr
Write down your operating system here ________________
You must have root permission and be sure that all users are logged off. Use any command you would use to halt
your system normally or use the commands listed below.
# sync;/etc/halt
Once the system is halted turn off the power to the system and any devices attached to it.
STEP 2: Addressing
External SCSI:
SurfSTOR subsystems have an
external SCSI ID select switch on the bottom or rear
panel of the enclosure. This switch corresponds with
the SCSI address of the DVD-RW unit inside the
enclosure. See Figure 2A below for a view of the ID
Selector:

Internal SCSI:
If you are installing an internal
DVD-RW
please note that all of the jumpers have
already been preset by Partners’ technicians to ID6
for compatibility with most Sun systems. Please do
not add or take off any other jumpers aside from the
SCSI ID selection jumpers.
For a reference of the standard SCSI addresses on
Sun Workstations refer to the following GENERIC
Solaris kernel setup below. The main point with
addressing is to make sure that no two devices have
the same address. See Figure 2B below for a view of
the unit and its connections:

Key:
CN1 --- 68-pin female SCSI connector.
CN2 --- 40-pin female IDE connector.
CN3 --- 4-pin power connector.
JP1 --- Sets Term Power to unit. Use pins 1 and 2
(left side).
JP2 --- Sets SCSI ID Selection and LED.
Typical SCSI Reservations:
IDs 0, 1, 2 and 3 are typically disk drives
(ID3=sd0 and is normally the boot disk mounted
internally).
IDs 4 & 5 are for tape drives or DVD-RW devices.
ID 6 is for bootable CD-ROM or DVD-RW devices.
ID 7 is for the SCSI Controller.
IDs 8 through 15 are for Tape Libraries and RAID
systems
