Remove & Replace Instructions
Overview and Notes
IMPORTANT: Overland Storage requires that all ARCvault parts in this procedure be
removed and replaced by an Overland Storage authorized service provider. Improper
installation can result in damage which voids existing warranties.
This document describes how to remove and replace the front bulkhead and flex cable
assembly in an ARCvault 2U library or loader from Overland. This is only for units with
a serial number 2B73400000 or higher.
WARNING: To reduce the risk of electric shock or damage to equipment, remove the
power cord before working on the unit.
Unpacking
Carefully unpack and verify that you have all the parts:
•2U bulkhead & cable assembly in anti-static bag
•These remove & replace instructions
•9 bags of screws and washers consisting of:
A magnetic #1 Phillips screwdriver, flatblade screwdriver, flashlight, and 2.0mm hex
driver are also needed.
Electrostatic Discharge Information
A discharge of static electricity can damage micro-circuitry or static-sensitive devices. To
help prevent Electrostatic Discharge (ESD), observe standard ESD precautions.

Removing the Old Assembly
All positions stated are relative to standing in front of the library (left, right, etc.). New
screws and washers are provided for all the removed items but you may want to retain the
old hardware in the large plastic bag. When you are done, discard the old hardware.
Remove Unit from Rack
WARNING: It is recommended that a mechanical lifter (or at least two people) be used to
prevent injury during rack removal or installation.
1. At the rear of the unit, remove the power cord and all cables.
2. Inside the front doors, loosen the retaining screws.
3. Using either a mechanical lifter or at least two people, remove the ARCvault unit
from the rack and place it on a secure, flat ESD surface.
Remove the Covers
1. Remove the six screws from the front top cover and set the cover aside.
2. Remove the eight screws from the rear top cover and set the cover aside.
Remove the Magazines
CAUTION: Always keep a loaded magazine level to prevent the tapes from falling out. Also,
don’t hold a magazine by just the handle; use both hands to support it.
1. For the right magazine:
a. Open the magazine door.
b. Release the solenoid latch (Figure 1) at the rear of the magazine.
Figure 1: Swing Solenoid Latch Release Handle Toward Rear
c. Carefully slide the magazine out.
2. For an ARCvault 24, repeat Step 1 for the left magazine.
Remove the Trackplate
CAUTION: If the trackplate is raised, removing the vertical motor causes it to quickly
descend. Support it as you disconnect the motor and then lower it slowly.

2U Bulkhead & Cable Assembly ARCvault Series R&R Instructions
1. At the rear of the trackplate, remove the vertical motor by removing the two
bracket screws and washers (Figure 2), and set the motor aside in the area of the
removed magazine.
Be careful not to damage the wiring connected to the rear of the motor.
Figure 2: Vertical Motor Bracket Screws
2. At the front of the trackplate, remove the hexhead screw and washer (Figure 3)
securing the Spring Assembly post.

a. Move it forward about an inch until the rear releases.
b. Simultaneously lift up and swing the rear end toward the center, freeing the
bracket.
c. Set the power supply on top of the drive without putting a strain on the cables.
Check Controller Card
In some cases, the F4, F5, or F6 fuse on the Controller card may also be blown and the card
needs to be replaced.

5. Position the J18 cable over the middle EMC strip above the white cables.
6. With the shiny side DOWN, insert the top EMC strip over the J18 cable, under the
front bulkhead (Figure 26), and under the rear cable tray lip next to the solenoid.
IMPORTANT: The top EMC strip must be inserted at least 3/16 inch (5mm) under the
front bulkhead. This results in an offset at the rear (Figure 26) which is correct.
Figure 26: Position EMC Covers Under Tray Lip
7. Gently fold all four cable tray tabs down flat.
Connect the Cables
CAUTION: Verify that you connect each cable to the correct plug to prevent damage to the
Controller card. Note that the bottom white cable does NOT go on the first plug.

NOTE: Be sure the right-rear gear is held in place by your thumb since the Vertical Motor is
no longer attached over it.
2. Position the front of the assembly between the two vertical gear racks (Figure 31).
The trackplate front gears should be in the area with no gear teeth setting on the top
gear tooth.
Figure 31: Position the Trackplate in Gear Rack Top Gaps (View from Rear)
3. Rolling the rear trackplate gears inward, engage the front gears and lower the
trackplate all the way down, visually verifying that it is flat on the bottom.
NOTE: Some resistance may be felt as the trackplate motor rubs against the bulkhead. This
is normal.
4. Slide the trackplate toward the rear of the unit and then slightly to the right to
engage the alignment tab with the groove in the right rear gear rack (Figure 32).
Figure 32: Alignment Tabs and Gear Rack (Top View)
5. Visually inspect the four large holes in the trackplate (Figure 33) to confirm that
it is flush to the bottom of the chassis.

Reinstall the Trackplate Motor
CAUTION: When attaching the motor, the trackplate MUST be all the way down and to the
right, and the alignment tab inserted in the gear rack slot (Figure 32).
1. If the trackplate was originally in an elevated position, using a flat blade
screwdriver, press firmly on the exposed gear tooth just above the bracket rear edge,
until the tooth surface is flush with the edge surface (Figure 34).
Figure 34: Align Gear to Bracket for Installation
2. Push the motor assembly down over the holes on trackplate.
The motor gear engages the gear rack as this is done.
NOTE: If the motor does NOT easily install, repeat Step 1. If you continue to have problems,
replace the vertical motor.
3. Holding the motor in place, insert two new M3x14mm screw (Bag 8) and M3 cup
washer (Bag 9) sets into the motor bracket holes (Figure 35).
NOTE: Verify that the cup of the washer is next to the screw head.
Figure 35: Vertical Motor Screw and Cup Washer
4. Reverify that all four corners of the trackplate are still flush with the bottom.
If not, remove the motor, realign the trackplate, and reinstall the motor.
Reinstall the Shuttle Flex Cable
1. Carefully position the flex cable assembly back inside the unit.

straight and untwisted.
5. Holding the new bracket next to the shuttle, plug the Signal and Power cables
into their sockets (Figure 37).
Figure 37: Flex Cable Connections on Shuttle
6. Using two new 4-20x5/16 panhead screws (Bag 2), attach the new cable bracket

Reactivating the Library
To complete the procedure, follow these final steps.
Verify the Library Operation
1. Using eight new M3x6mm screws (Bag 5), reattach only the top rear cover.
2. Lay the front cover on the unit (but DO NOT attach it at this time).
During POST, the shuttle touches the front cover to set the positioning software.
3. Power on the library (with no magazines) and let it run POST.
NOTE: If there are any problems, contact Overland Support.
4. Using six new M3x6mm screws (Bag 5), reattach the front cover.
Return Library to Rack
1. Using a lift or two people, reinstall the library into the rack.
2. Tighten the retaining screws on the front.
3. Open the doors, reinsert the media magazines and close the doors.
4. At the rear, reconnect the host interface and network cables.
5. Plug in the power cord and power on the unit.
Train the Library
1. Verify that all magazines have only the middle row of slots filled with media.
The top and bottom rows MUST be empty.
2. Log into RMU at the Service security level.
Contact Overland Support if you have forgotten your password.
3. Click Functions > Start Training.
NOTE: This process takes up to 30 minutes.
Once the training is complete, log out of RMU.
4. Reload the normal media and reboot the library.
Return Old Bulkhead
1. Pack the old bulkhead and cable assembly in the same box that the new part
came in.
2. Follow the enclosed instructions to return the part to Overland Storage.
