Chassis Replacement Instructions
IMPORTANT: These instructions are for a DX2 chassis with captive screws at the top of the side flanges. For units with the screws
at the bottom of the flanges, refer to document 10400349-003.
This document describes how to remove and replace the chassis
of a SnapServer DX2 appliance from Overland Storage.
WARNING: To reduce the risk of electric shock or damage to
equipment, always remove any power cords while working
with the unit.
AVERTISSEMENT: Pour réduire le risque de choc électrique ou
endommagement de l'équipement, retirez toujours les cordons
électriques en travaillant avec l'appareil.
CAUTION: While working with the unit, observe standard
Electrostatic Discharge (ESD) precautions to prevent damage
to micro-circuitry or static-sensitive devices.
Prepare the Unit
Power Off and Disconnect
If the unit is still running, power it down cleanly:
1. Use the Web Management Interface to shutdown the
server (
Maintenance > Reboot and Shutdown > Shutdown ).
2. When all the LEDs are off, disconnect the power cords.
3. Disconnect the remaining cables from the unit.
Remove the Front Bezel
Carefully take hold of the front bezel and pull it straight out
from the appliance until the magnets release. Set it aside.
Remove the Drives
IMPORTANT: Overland recommends that you remove the disk
drives to lessen the unit’s weight prior to removal.
NOTE: Do not remove the disk drives from their carriers. Doing so
voids the drive warranty.
Remove all the drive carriers. Blank carriers can be left in
place.
1. Press the release button on the right side of the carrier.
2. Using the built-in handle, pull the drive carrier out.
3. Set the carrier on an secure surface.
4. Repeat Steps 1–3 for all the remaining drive carriers.

Remove Unit from Rack
WARNING: It is recommended that a mechanical lifter (or at
least two people) be used during rack installation or removal
to prevent injury.
AVERTISSEMENT: Pour éviter toute blessure il est
recommande qu'un monte-charge (ou deux personnes au
moins) soit utilisé lors de l'installation ou de l'enlèvement du
support.
1. Release the two captive screws on the front flanges, and
slide the chassis out until it stops.
2. Position the lifter in front of the unit, release the rail
locks, and slide the chassis out onto the lifter.
3. Move the chassis onto a secure surface.
4. Unpack the new chassis and place it next to the old one.
Transfer Components
Move Inner Sliding Rails
You need to move the attached inner slide rails to the new
chassis:
1. Remove and retain the three screws holding one of the
rails on the side of the old chassis.
2. Position the rail on the same side on the new chassis,
and secure it with the retained screws.
3. Repeat Steps 1–2 for the other rail.
Remove Top Panels
1. At the old chassis, remove and retain the six screws on
the sides and top securing the rear top panel.
2. Slide the panel toward the rear about one-half inch
(1.25cm), lift it off, and set aside.
3. Repeat Steps 1–2 for the new chassis.
Move DIMMs
All installed DIMMs need to be moved to the new chassis:
1. Remove a DIMM in the old chassis by pressing the
latches on each end and popping the DIMM out.
2. Position the DIMM in the same slot of the new chassis,
lining up the DIMM notch with the guide in the slot.
3. Firmly press the DIMM down until the latches in place.
4. Repeat Steps 1–3 for any other DIMMs.
Move the Power Supplies
1. While pressing the release latch toward the handle, pull

than one-half inch (1.25cm) extending out over the rear
of the unit.
2. Slide the panel forward until it is fully seated.
3. Using the six retained screws, secure the panel.
4. Repeat Steps 1–3 for the old chassis.
Install New Chassis in Rack
Install the Chassis
1. Using the mechanical lifter, position the chassis in front
of the rack rails.
2. Pull the middle rails out of the rack, connect those rails to
the server rails, and slide the chassis all the way into the
rack.
3. Secure the unit using the two captive screws on the
front flanges.
Reinstall the Drives
1. Position a drive carrier in front of its empty slot.
2. Slide the carrier in until the latch locks (clicks).
3. Repeat Steps 1–2 for all remaining drive carriers.
IMPORTANT: To maintain proper airflow and cooling, a drive
carrier or a blank carrier must be installed in every slot. No
empty slots are allowed.
Reattach the Bezel
1. Position the bezel with the horizontal tabs aligned inside
the top and bottom edges of the chassis.
2. Move it toward the appliance until the magnets contact.
3. Verify that the bezel is aligned properly, all the LEDs are

Chassis Replacement Instructions
Important – Read This Before Continuing
If the GuardianOS on the new chassis is different from the
version on the disk drives, the appliance goes through a special
initialization and synchronization process that can take up to
10 minutes to complete. During this time, the Status LED
flashes an alternating green and amber pattern.
CAUTION: Under no circumstances should power be removed
while the system is in this state! Doing so may render the
appliance inoperable.
Once initialization is complete, the system automatically
reboots and the Status LED displays a solid green color.
If the GuardianOS versions are the same on both the chassis
and drives, the appliance boots normally.
Complete the Exchange
Validate the System
Log onto the SnapServer Web Management Interface and
verify your the connections and settings. Check flashing front
LEDs indicating errors. Refer to the user guide to resolve.
NOTE: If the server was configured as an EDR master console, new
licenses must be installed, as they are based on the server number.
If there are any problems, contact Overland Technical Support:
