SnapServer™DX2 / SnapScale™X2 Node
Add-on/Spare DIMM Instructions
This document describes how to either add a additional DIMM
(Dual In-line Memory Module) to or remove and replace an
existing DIMM from a SnapServer DX2 or SnapScale X2 node
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.
IMPORTANT: Using DIMMs that are not supplied by
Overland Storage will void your warranty. Overland
Storage DIMMs have been tested and verified to operate
properly with Overland appliances. Failure to use qualified
DIMMs may impact data availably or lead to data loss.
Register the Add-on DIMM
NOTE: If you are only replacing an existing DIMM, skip to the next
section, “Prepare the Unit.”
When adding a DIMM to your server, you must first register it
to activate the warranty. Technical and warranty support are
not available until this is done:
1. Go to the Overland Storage website
(http://www.overlandstorage.com/).
2. Select
Service & Support > My Products .
3. At the Site Login, enter your e-mail address and
password, and click
GO .
4. Click the
Manage Products button.
5. From the Product Selector drop-down list, select the DX2
or X2 in which you are installing the DIMM.
6. Click
Add a Component .
7. Enter the DIMM information.
8. Click
Save & Exit .
IMPORTANT: Your warranty certificate will be emailed to you.

Add-on/Spare DIMM Instructions
Prepare the Unit
Power Off and Disconnect
1. Power off the unit/cluster:
• SnapServer: Press the Power button.
• SnapScale: There are two power-off options available.
•Shut off the entire cluster by using the Web
Management Interface (
Maintenance > Shutdown/
Restart > Shutdown
).
By shutting down the entire cluster, no peer sets
will need to be rebuilt when it is reactivated.
However, the cluster will be offline and unavailable
during the repairs. This option is recommended
when all nodes are having memory added.
•Shut off just the affected node by briefly pressing
the Power button on a node.
By shutting down only the node, the cluster remains
online and active. However, some peer sets will be
operating with either less (3x replication) or no (2x
replication) redundancy while the node is down and
afterwards when the peer sets are being rebuilt.
This option is recommended when only one node is
having memory added.
2. When all the LEDs are off, disconnect the power cords.
3. Disconnect all the 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 reduce the unit’s weight prior to removal. They must
be replaced in the same bays when done.
NOTE: Do not remove the disk drives from their carriers. Doing so
voids the drive warranty.
Remove all the drive carriers, noting from which bay they were
removed. 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.

Add-on/Spare DIMM Instructions
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.
Remove Top Panel
1. Remove and retain the four screws on the sides and two
screws on the top securing the rear top panel.
2. Slide the panel toward the rear about one-half inch
(1.25cm) and lift it off.
3. Set the top panel on a safe surface.
Install DIMM
DIMM Configurations
DIMMs go into specific slots based on the motherboard used.
NOTE: Failure to add the DIMM to the next slot in the order may
result in the unit not recognizing the extra memory.
Motherboards (type A) with black-blue-blue-blue DIMM slots
come with a DIMM in slot 1. Additional DIMMs are added in
the order shown (2, 3, and then 4).
Motherboards (type B) with blue-black-blue-black DIMM slots
come with a DIMM in slot 1. Additional DIMMs are added in
the order shown (2, 3, and then 4).
Install Additional DIMMs
NOTE: If you are only replacing an existing DIMM, skip to the next
section, “Replace DIMMs.”
1. At the appropriate empty DIMM slot (refer to “DIMM
Configurations”), press both latches down.
2. Align the DIMM in the slot, lining up the DIMM notch
with the guide in the slot.
3. Firmly press the DIMM down until the latches lock.
Continue with “Reinstall Top Panels.”

Add-on/Spare DIMM Instructions
Replace DIMMs
1. Remove the old DIMM by pressing the latches on each
end and popping the DIMM out.
Set the DIMM aside on an ESD-safe surface.
2. Position the new DIMM in the same slot, lining up the
DIMM notch with the guide in the slot.
3. Firmly press the DIMM down until the latches lock it in
place.
Reinstall Top Panels
1. Position the top panel with no more 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.
Reinstall in Rack
Reinstall 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 connecting them to
the inner rails, and slide the chassis into the rack.
3. Secure the unit using the two captive screws on the
front flanges.
Reinstall the Drives
Return the drive carriers back to their original bays:
1. Position a drive carrier in front of its empty bay.
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 bay. No
empty bays are allowed.
Reattach the Bezel
1. Position the bezel with the tabs aligned inside the top and
bottom edges of the chassis.
2. Move the bezel toward the unit until the magnets make
contact.
3. Verify that the bezel is aligned properly, all the LEDs are
visible, and the Power panel is cleanly centered in its bay
on the right flange.

Add-on/Spare DIMM Instructions
Reattach Cables and Power Cords
1. Reattach all cables to the same connections as before.
2. Attach the power cords.
3. At the front, press the power switch to power it ON.
For SnapScale, depending on the shutdown procedure
used:
•After adding memory to all nodes, at the front of
each node in the cluster, press the power switch to
power each node ON.
•After adding memory to a single node only, press the
power switch to power ON that node. When it
finishes booting, the node rejoins the cluster and
rebuilds peer sets. Let all peer sets complete their
rebuilding process before reconfiguring any
additional nodes.
Verify Memory
1. In the Web Management Interface, go to Monitor > System
Status
.
2. Verify the Memory amount is correct.
The usual DIMM memory GB rounding variations apply.
If necessary, click Refresh to display the current settings.
3. Click Close.
Return Old Part to Overland
1. Place the old part in the anti-static bag and put it in the
replacement part’s box.
2. Use an RMA to return the part to Overland Storage.
