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.

Remove the Bezel

1. If locked, unlock the bezel.

2. Press the release button toward the center and pull the

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.

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
