Sun 100/150 Installation Manual
3.2. M2284 (Fujitsu 169-MByte) Disk
The 169-MByte disk subsystem is currently shipped in several boxes: the disk drive itself, the
power supply for the subsystem, and the mounting hardware for a 19-inch rack each come pack-
aged separately.
When you follow the unpacking and mounting procedures below, we recommend that you have
the Fujitsu M22aX Fized Di,1e Unit, Cultomer Engineering Manual close at hand. This manual
contains information essential to the process.

1.
Open the 169-MByte disk's outer shipping carton by removing the four white plastic pins
on the lid (squeeze together wings and pull), and then lifting off the lid.
2. When the lid is removed, the internal carton containing the disk subsytem is exposed. Lift
out the internal carton, and take off the corner pads.
3. Cut open the internal· carton, and remove the styrofoam packing material. This exposes
the power and control cables, on the sides of the box; the front panel for the unit; and the
subsystem itself, wrapped in a polyethylene bag.
4. With another person, lift the unit out of its bottom pad. Grasp the unit at the bottom to
avoid damage to the sub-assemblies.
We recommend that you save the salvageable shipping carton and packing material for
future use in case the product must be reshipped.
S. Before applying power to the subsystem, you must unlock the spindle, the actuator, and
the motor on the disk drive. These are locked during shipment to protect the subsystem,
and must be locked any time the unit is moved. For procedures, see the Fujitsu M22aX
Fized Di,.1e Unit, Cultomer Engineering Manual, sections 3.4.3, 3.4.4, and 3.4.5, respectively.
If you are mounting the subsystem, and you are mounting it such that you can get to its
underside when it \s mounted (necessary to unlock the spindle), you should mount the unit
before unlocking the svindle, actuator, and motor for maximum protection. Go on with
step 6 for mounting instructions.
6. To mount the suhsystem, first mount the slides at the chosen position in the rack. Have
one or two brawny folks around to help you lift the unit gently into position. When you
are completely tArougA with sliding the disk around, you can screw the pair of retaining bars
onto the front of the subsystem, and snap on the front panel.
7. The M2284 disk drive is connected to its power supply unit via three cables.
CAUTION:
Turn off the power and disconnect the power cord before opening up the Sun
Workstation's enclosure, doing cabling of any sort, or altering peripheral/board configurations.
3-4
There are two power cables known
as
the 'A' (AC) and 'B' (DC) power cables, and there is
a power control cable for power-up sequencing when multiple disk drives are installed. The
'A' cable (12-pin) connects to PWI near the center. rear of the power supply unit. The 'B'
cable (IS-pin) connects to PW2 near the top right rear of the unit. The power control
cable (9-pin) connects to
CN18~
just to the left of PW2.
