SnapServer™DX1
Add-on/Spare DIMM Instructions
This document describes how to add a second DIMM (Dual
In-line Memory Module) or remove and replace an existing
DIMM in a SnapServer DX1 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 the SnapServer appliance. Failure to use qualified
DIMMs may impact data availability or lead to data loss.

NOTE: If you are only replacing an existing DIMM, skip to the next
section, “Prepare the Unit.”

Add-on/Spare DIMM Instructions
Remove the Bezel
Carefully take hold of the front bezel and pull straight out from
the appliance 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.
This process applies to both drive assemblies and blanks:
1. Press the release button on the right side of the carrier.
2. Using the handle, pull the assembly out.
3. Set the assembly on an ESD-safe surface.
4. Repeat Steps 1–3 for each remaining carrier.
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. Based on the mounting system, carefully remove the
appliance from the rack as follows:
• Fixed brackets – Remove and retain the four screws
from the front flanges and move the unit onto the lifter.
• Sliding rails – Release the two captive screws, slide
the unit out until it stops, release the rail locks, and
slide the unit out and onto the lifter.
2. Move the unit onto a secure ESD-safe surface.
Install/Swap DIMMs
Remove Top Panel
