Spare Sliding Rail Kit Instructions
This document describes how to remove and replace the sliding
rack rails for a SnapServer XSR 120, SnapExpansion XSR
unit, 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.
WARNUNG: Um das Risiko eines elektrischen Schlags oder
Schäden am Gerät zu vermeiden, ziehen Sie stets den
Netzstecker, bevor Sie an der Einheit arbeiten.
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. Power off the server/cluster:
•SnapServer: Use the Web Management Interface to
shut down the server ( Maintenance > Reboot and
Shutdown > Shutdown
).
•SnapScale: There are two power-off options available.
•Shut off the entire cluster by using the Web
Management Interface (
Maintenance > Shutdown/
Restart > Shutdown
).
This is the recommended option. 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.
•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.
2. When all the LEDs are off, disconnect the power cords.
3. Disconnect the remaining cables from the unit, noting
their locations.

Remove the Front Bezel
1. Carefully take hold of the front bezel and pull it straight
out from the appliance until the magnets release.
2. Set the bezel aside on a secure surface.
Remove the Drives
IMPORTANT: Overland recommends that you remove the disk
drives to reduce the unit’s weight prior to removal.
Remove all the drive carriers. For SnapScale, note from which
bay they were removed. Blank carriers can remain in the bays.
NOTE: Do not remove the disk drives from their carriers. Doing so
voids the drive warranty.
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 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.
WARNUNG: Um Verletzungen zu vermeiden, empfehlen wir
zur Rack-Installation oder -Deinstallation die Nutzung einer
mechanischen Hebehilfe (oder mindestens zwei Personen).
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. Remove and retain the four screws securing the unit to
the rack.
2. With a lifter positioned in front of the array, release the
rail locks and slide the chassis out onto the lifter.
3. Move the chassis onto a secure surface.
Replace the Rails
Prepare the Rails
1. Select a new rail assembly and slide the inner rail out
until it stops.
2. Push the inner rail release latch forward and remove the
inner rail.
3. To retract the middle rail, release the lock (1) and slide it
back into (2) the outer rail.
4. Repeat Steps 1–3 for the other rail assembly.
5. At the rack, remove the existing rails, making a note of
their position.

Attach New Inner Rails to Unit
1. Remove and retain the screws securing the right rail to
the chassis, and set the old rail aside.
2. Align the new inner rail against the right side with the
front end toward the chassis front.
3. Using the supplied screws, secure the rail.
4. Repeat Steps 1–3 for the left side rail.
Optional Steps for Thicker Rack Rails
NOTE: For rack rail sizes of less than 3mm, skip this procedure
and proceed to “Attach Outer Rails to Square-holed Rack.”
For rack rails thicker than 3mm, the sliding rail anchors
cannot be seated without exerting extreme force and
potentially damaging the sliding rail kit. The brackets need to
be removed from each end of the slide rails to make the anchors
seat securely.
1. Locate the bracket on the end of a slide rail.
2. Remove the center screw securing the bracket.
3. Push the bracket toward the end of the rail, prying the
back of the bracket upward to unseat and remove it.
4. Repeat Steps 1–3 for the other end of the rail.
5. Repeat Steps 1–4 for the other rail.
Attach Outer Rails to Square-holed Rack
NOTE: The new rails should be attached to the same front and
back vertical rack holes that the old rails used.
1. Position the front of one of the rails inside and in line with
the front vertical rail mounting holes (1).
2. Move the rail forward until the rail anchors are through
the holes.
3. Push the rail toward the outside of the rack (2) until the
rail locks snap into place.
4. At the rear (3), slide the outer rail in or out to fit between
the vertical rails (a) and repeat Steps 1–3 to secure it (b).
NOTE: Make sure the rear holes are the same height as the
front holes so the rail is level. For 3mm or thicker racks, use the
supplied two screws to secure the rail rear ends to the rack.
5. Repeat Steps 1–4 for the other rail.
Reassemble the Unit
Return Chassis to Rack
1. Slide out the middle rails from the rack.
2. Using the mechanical lifter, position the chassis in front
of the rack.
3. Insert the inner rails into the middle rails and slide the
unit into the rack.
4. Using the four retained screws, secure the unit.

Reinstall Drives
1. Position a drive assembly in front of its empty bay.
For SnapScale, they must be returned to the bay they
were removed from. Refer to the number on the assembly.
2. Slide the assembly in until the latch clicks, securing it.
3. Repeat Steps 1–2 for all remaining drive carriers.
IMPORTANT: To maintain proper airflow and cooling, a drive
assembly or a blank carrier must be installed in every bay. No
empty bays are allowed.
Reattach Cables and Power Cords
1. Reattach all cables to the same connections as before.
2. Attach the power cords.
3. At the front of the unit, press the power switch for less
than a second to power the unit ON.
Reattach the Bezel
1. Position the bezel with the tabs aligned inside the top
and bottom edges of the chassis.
2. Move bezel toward the unit until the magnets connect.
3. Verify that the bezel is aligned properly, all the LEDs are
visible, and the Power panel is centered in the left flange.
Return Replaced Parts to Overland
1. Place the old rails in the packing bag and put them in the
replacement part’s box.
2. Use an RMA to return the part to Overland Storage.
