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.

Spare Fan Instructions

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 slots when done.

NOTE: Do not remove the disk drives from their carriers. Doing so voids the drive warranty.

Remove all the drive carriers, noting from which slot they were removed. 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.

Remove Top Panel

1. Remove and retain the four screws on the sides and two

screws on the top securing the rear top panel.

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

(1.25cm) and lift it off.

3. Set the top panel on a safe surface.

5. Pull the fan up and out of the chassis.

Install New Fan

1. Slide the new fan down into the fan bulkhead slot.

2. Push the fan down until the clamps lock (click).

3. Carefully run the fan cable through the fan bulkhead into the chassis.

4. Connect the fan cable onto the same socket on the motherboard.

5. Position the cable above the bridge lance (metal loop) on the chassis floor and use a new tie-down to secure the cable to the bridge lance.

Fan cables 1 and 2 are looped and tied down together.

Reinstall Top Panels

1. At the new chassis, position the top panel with no more than one-half inch (1.25cm) extending out over the rear of the unit.

Reinstall the Drives

Return the drive carriers to their original slots:

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

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

1. Reattach the data cables to the same connections previously used.

2. Attach the power cords.

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

For SnapScale, turn all the nodes ON.
