SnapScale™X4 Node
Chassis Replacement Instructions
This document describes how to swap out the chassis of a
SnapScale X4 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: For SnapScale nodes running ROS 3.x,
contact Overland Technical Support before attempting
this procedure. Go to http://docs.overlandstorage.com/
support for details.
Prepare the Node
Power Off and Remove
1. At the Web Management Interface, go to Storage > Nodes
and click the node name to view the
Node Properties page.
2. Click
Remove Node from SnapScale and confirm.
3. If the node is running, wait for the node to reboot as an
Uninitialized node, and then press the Power button on
its left flange to shut it down.
4. When all the front LEDs are off, disconnect the power
cords of the node.
5. Disconnect all remaining cables from the node.

Chassis Replacement Instructions
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 drive bays in the new node.
NOTE: Do not remove the disk drives from their carriers. Doing so
voids the drive warranty.
Remove all the drive and blank carriers, noting from which slot
they were removed.
1. Press the release button on the right side of the carrier.
2. Using the built-in handle, pull the carrier out.
3. Number the carrier and set it on a secure surface
4. Repeat Steps 1–3 for all the remaining carriers, front and
rear.
Remove Node 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. With a lifter positioned in front of the array, release the
two captive screws on the front flanges, and slide the
chassis out until it stops.
2. Release the rail locks and continue to 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 screws holding one of the rails on
the side of the old chassis.
2. Slide the rail toward the rear, and remove it.
This may require some force as it is a tight fit.
3. Position the rail against the side of the new chassis with
the locking tabs going through the holes on the rail.
4. Slide the rail toward the front to lock it and secure it with
the retained screws.
5. Repeat Steps 1–4 for the other rail.

Chassis Replacement Instructions
Remove Top Panels
1. At the old chassis, remove and retain the three screws
on the sides and one screw on the top securing the rear
top panel.
2. Carefully lift the panel off.
3. Set the panel on a safe surface.
4. Remove the air shroud over the motherboard.
5. Repeat Steps 1–4 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 it latches (clicks).
4. Repeat Steps 1–3 for any other DIMMs.
Move the Power Supplies
1. While pressing the release latch toward the handle, pull
the handle to slide the module out of the old chassis.
2. Slide the power supply into the same bay of the new
chassis until it locks (clicks).
3. Repeat steps Steps 1–2 for the remaining power supply.
Move Optional PCIe Cards
If optional PCIe cards are installed, move them to the new
chassis, placing them in the same slots.
1. In the new chassis, remove the slot cover where the card
is supposed to go, retaining the screw and cover.
2. In the old chassis, remove and retain the screw of the
card being moved.
3. Grasp the card and carefully pull it straight up and out of
the socket making sure the bracket does not catch.
4. Insert the card into the same socket in the new chassis.
Push the card down firmly to ensure a good connection in
the socket.
5. Use the retained screw to secure the card bracket.
6. Using the retained screw, install the slot cover in the old
chassis where the card was removed.
7. If other PCIe cards exist, repeat Steps 1–6 for each card.

Move the Fans
1. In the old chassis, depress the tab on the side of the fan to
unlock and remove it along with its housing.
The fan's power connections automatically detach.
2. At the new chassis, slide the fan into the same slot until a
click is heard.
3. Repeat Steps 1–2 for all the remaining fans.
Reinstall Top Panels
1. Replace the air shroud over the motherboard.
2. Position the rear top panel over the unit and seat it.
3. Using the 4 retained screws, secure the panel.
Three screws go on the sides and one on top.
4. Repeat Steps 1–3 for the old chassis.
Install New Chassis in Rack
Install the Chassis
1. Using the mechanical lifter, position the new chassis in
front of the node’s existing rack rails.
2. Pull the middle rails out of the rack, connect those rails to
the node 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 Carriers
Return the drive and blank carriers to the same drive bays
they were removed from:
1. Position a carrier in front of its empty bay and slide it
all the way in until it makes contact with the backplane.
2. Close the latch, locking the carrier in place.
3. Repeat Steps 1–2 for all remaining carriers, front and
rear.
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. Insert the bezel tabs in the tab slots on the left.
2. With the tabs still in the slots, move the right side of the
bezel toward the unit until the latch clicks closed.
3. If required, relock the lock.

Chassis Replacement Instructions
Reattach Cables and Power Cords
1. Reattach all cables to the same connections as before,
with the Client and Storage switches correctly connected.
2. Attach the power cords.
3. At the front of the node, press the power switch to power
it ON.
Important – Read This Before Continuing
If the RAINcloudOS 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 light
blinks, alternating between a single- and double-blink.
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 RAINcloudOS versions are the same on both the chassis
and drives, the appliance boots normally.
Complete the Exchange
Add Node to Cluster
NOTE: If the node was not running before removing it from the
cluster, contact Overland Technical Support at http://
docs.overlandstorage.com/support.
1. Log onto the Web Management Interface and go to
Storage > Nodes by clicking the Nodes quick link.
2. Click
Add Nodes and follow the wizard to add the
refreshed node back to the cluster.
Return Old Parts 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.
