Overland Storage SnapServer DX2 Leitfaden

SnapServer™DX2

Chassis Replacement Instructions

IMPORTANT: These instructions are for a DX2 chassis with captive screws at the bottom of the side flanges. For units with the

screws at the top of the flanges, refer to document 10400403-002.

This document describes how to remove and replace the chassis

of a SnapServer DX2 appliance 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

If the unit is still running, power it down cleanly:

1. Use the Web Management Interface to shutdown the

server (

Maintenance > Reboot and Shutdown > Shutdown

2. When all the LEDs are off, disconnect the power cords.

3. Disconnect the remaining cables from the unit.

Remove the Front Bezel

Carefully take hold of the front bezel and pull it straight out

from the appliance until the magnets release. Set it aside.

Remove the Drives

IMPORTANT: Overland recommends that you remove the disk

drives 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.

Remove all the drive carriers. Blank carriers can be left in

place.

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 carrier on an 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.

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. Release the two captive screws on the front flanges, and

slide the chassis out until it stops.

2. Position the lifter in front of the unit, release the rail

locks, and 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 three screws holding one of the

rails on the side of the old chassis.

2. Position the rail on the same side on the new chassis,

and secure it with the retained screws.

3. Repeat Steps 1–2 for the other rail.

Remove Top Panels

1. At the old chassis, remove and retain the four screws

on the sides securing the rear top panel.

2. Slide the panel toward the rear about one-half inch

(1.25cm), lift it off, and set aside.

3. Repeat Steps 1–2 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 the latches in place.

4. Repeat Steps 1–3 for any other DIMMs.

Move the Power Supplies

1. While pressing the release latch toward the handle, pull

the power supply handle to slide 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 PCIe Cards

All installed PCIe cards need to be moved to the new chassis:

1. For both chassis, release and lift the bracket lock.

2. If needed, remove any extra rear slot covers on the new

chassis to match the old chassis slots that have cards.

3. Noting their positions, remove the four orange SAS

cables from the SAS expansion card in the old chassis.

4. Grasp a PCIe card and carefully pull it straight up and

out of the socket.

5. Insert the card into the same socket in the new chassis,

positioning the cover bracket in the rear slot.

6. Repeat Steps 4–5 for any other PCIe cards.

7. Install on the old chassis any removed slot covers.

8. For both chassis, fold down and press the bracket lock

until it clicks into place securing the slot covers.

9. At the new chassis, release the tie-wraps and connect the

orange SAS cables to the ports on the SAS card.

Install Tie-Wraps

To prevent damage during return, the orange SAS cables in the

old chassis need to be secured using the tie-wraps provided.

1. Carefully position the three shorter orange cables back

along the black wrapped portion of the cable and loosely

secure them temporary with a tie-wrap.

2. Run the remaining long cable (P3) through the loose tie-

wrap and then tighten the tie-wrap.

Be sure the short cables are tight enough that there is no

slack or movement.

3. Position the long cable further down the black wrapped

cable and secure it near its plug with a tie-wrap.

Be sure it is also tight with no slack or movement.

Reinstall Top Panels

1. At the new chassis, position the top panel on the DX2 with

no more than one-half inch (1.25cm) extending out over

the rear of the unit.

2. Slide the panel forward until it is fully seated.

3. Using the four retained screws, secure the panel.

4. Repeat Steps 1–3 for the old chassis.

Install New Chassis in Rack

Install the Chassis

1. Using the mechanical lifter, position the chassis in front

of the rack rails.

2. Pull the middle rails out of the rack, connect those rails to

the server 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 Drives

1. Position a drive carrier in front of its empty slot.

2. Slide the carrier in until the latch locks (clicks).

3. Repeat Steps 1–2 for all remaining drive carriers.

IMPORTANT: To maintain proper airflow and cooling, a drive

carrier or a blank carrier must be installed in every slot. No

empty slots are allowed.

Reattach the Bezel

1. Position the bezel with the horizontal tabs aligned inside

the top and bottom edges of the chassis.

2. Move it toward the appliance until the magnets contact.

3. Verify that the bezel is aligned properly, all the LEDs are

visible, and the Power panel is cleanly centered in its slot

on the right flange.

Reattach Cables and Power Cords

1. Reattach the network cables to the same connections.

2. Reattach the power cords.

3. At the front, press the power switch to power it ON.

Important – Read This Before Continuing

If the GuardianOS 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 LED

flashes an alternating green and amber pattern.

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 GuardianOS versions are the same on both the chassis

and drives, the appliance boots normally.

Validate the System

Log onto the SnapServer Web Management Interface and

verify your the connections and settings. Check flashing front

LEDs indicating errors. Refer to the user guide to resolve.

NOTE: If the server was configured as an EDR master console, new

licenses must be installed, as they are based on the server number.
