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.

•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.
