Overland Storage SnapExpansion DX Series Replacement Instructions

Chassis Replacement Instructions
This document describes how to remove and replace the chassis
of a DX-series SnapExpansion unit 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

1. At the head unit, use the Web Management Interface,
select System Maintenance > Reboot and Shutdown >
Shutdown to stop services and power it OFF.
This also powers OFF all the expansion units.
2. When all the LEDs of all the units are off, disconnect the
power cords from the expansion unit.
3. Disconnect the SAS cables from the unit noting if they
were plugged into the IN or OUT socket.

Remove the Front Bezel

Carefully take hold of the front bezel and pull it straight out
from the unit until the magnets release. Set it aside.

Remove the Drives

IMPORTANT: Overland recommends that you remove the
drive assemblies 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.
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 drive assembly on an ESD-safe surface.
4. Repeat
Steps 1–3 for all remaining drive and blank
carriers.

the top of the flange, refer to document 10400404-001.
