1) Make sure the power cord is disconnected from line power.
2) Release the lockdown mechanism on the PowerLoader™, using the Lockdown
Screw on the back (lower right) of the unit.
3) Turn the spring-loaded lockdown screw on the back counter-clockwise until the
lockdown mechanism releases from the shuttle.
4) Turn the Power "ON" and begin operations

The PowerLoader™ desktop model requires no mechanical assembly for
mounting Place the unit on a desk, table, server top, or other stable,
horizontal surface. Make sure the cooling grilles at the rear of the unit are
not obstructed. Allow two inches of clearance behind the rear panel.

To convert a tabletop PowerLoader™ to a rack mount model, order the
Rackmount Conversion Kit (Part Number 106070-001).
If your PowerLoader™ is already rack-mount configured, See "Installing
Rack Mount Model".

With the inner rack slides attached to the LibraryPro™ unit and the
intermediate/outer slides separated from the inner slides, you can install
the outer rack slides in the rack.
1) Locate the screw holes in the front and rear rails of the cabinet or equipment
rack where the drive is to be installed.
2) Loosely assemble a mounting bracket to each outer slide, using two 10-32
screws and a nut-plate for each. Select slots in the mounting brackets so the
length of the assembly equals the distance between the front and rear rails of
the rack.
3) Fasten each outer slide behind the front rail of the rack using two 10-32 low-
profile screws and one nut plate.
13) Slide the module into the rack as shown in Figure 2–11, and tighten the
thumbscrews..

Visually inspect the shipping containers and notify your carrier immediately of any
damage. Verify the contents against the packing list. If parts are missing or the
equipment is damaged, notify your representative. Always save the containers and
packing materials for any future reshipment.
To set up the PowerLoader, do the following:
•
Follow the directions in the shipping container to unpack the PowerLoader.
•
Save the packing materials in case you need to return the unit for repairs.
•
You do not have to assemble anything.
Place the PowerLoader on a stable horizontal surface with at least a 2-inch clearance
behind the chassis to allow sufficient cooling air to flow freely from the fan, or mount
your unit in an equipment rack using the Rack Mount Installation section found in the
User and Installation Manual or Rack Mount Quick Install card.

2) Turn off the unit and remove all power.
3) If necessary, reposition the unit for easier access to the back panel..
4) Push in the spring-loaded lockdown screw on the back of the unite and turn it
clockwise..
5) Release the clip, allowing it to fit into the center of the leadscrew bearing.

4) Fasten each of the mounting brackets to the front of the rear rail of the rack
using two standard 10-32 screws and one nut plate.
5) Tighten the screws installed in step 2.
6) If they are not already locked, pull the intermediate slides toward the front
(out of the rack) so that they lock in the extended position.

7) Install the Library unit into the rack:
a. In front of the rack, lift the module to its installed height.
b. Engage the inner slides mounted on the module with the
intermediate slides protruding from the rack
c. Slide the module toward the rack until the inner slide's lock
engages the intermediate slides.
d. Depress the lock tab and continue until the lock tab engages in
the locking hole shown in the figure below. This leaves the
entire module protruding from the rack, locked in position,
supported by slides.

Each drive is wired to an independent bus, with a pair of SCSI connectors.
Drive 1 shares a SCSI bus with the PowerLoader™'s robotics. To fully use
the bus bandwidth, connect all the SCSI buses together as shown Figure 2–
44. The insets in show how to connect the SCSI cable, the jumper cables and
the terminator for one or two-drive units.

Connectors, SCSI Terminator & Cable
Each of the drives in the PowerLoader™ and the robotics is a separate SCSI
device. When any two or more devices are connected to the same SCSI bus,
each separate SCSI device must be assigned a unique SCSI address. For
information on assigning SCSI addresses, see the Configuration section.
To connect a PowerLoader™ to a host computer, the host must have at least
one Wide SCSI controller and the appropriate driver software. The controller
must be LVD/SE or differential, as required to match the module in 34-pair
twisted-pair.

of performance, use the highest-quality interface cables from a
reputable manufacturer of computer cables. All SCSI cables used
with the unit should meet the following requirements:

8) Press inward (toward the module) on each of the inner slide locks to permit
the intermediate slides to move toward the rack.
9) Slide the module in and out several times as shown in Figure 2–10, ensuring
that the inner and outer slide locks engage, and that the module does not
bind against the slides.If they are not already locked, pull the intermediate
slides toward the front (out of the rack) so that they lock in the extended
position.
10) If binding or misalignment with other rack devices occurs, loosen the four
screws that secure the slides to the front rails and the four screws that secure
the slides to the rear rails and realign the module. Retighten the screws.
11) If necessary, repeat steps 9 and 10 until the module does not bind against the
slides.
12) Install two clip nuts on each front rail at the height of the front panel
mounting screws (thumbscrews).

The LibraryPro™ is designed with many configuration options, each
offering multiple settings to support a variety of applications and
platforms. The setting of each option is stored in non-volatile memory in
the module. For most applications, you do not have to change the factory
default settings. If you need to change the configuration, go on to the nex
section. If you are uncertain whether you need to change a setting, conta
your Technical Support representative.
To change settings, use the Control Panel. For an overview of how the
Control Panel works, and a description of the functions of the buttons,
indicators and display, refer to Entering the Menu Mode, Exiting the Men
Mode, and Navigating through the Menu Structure in the PowerLoader
User and Installation Manual.
You can change the settings using the procedure in How to Customize
Configuration later in this chapter. Consult your host computer and
software documentation to determine which settings you might have to
change.
