REO™ 4500x Expansion Appliance

Quick Start Guide

This document describes how to unpack and install a REO 4500x Expansion Appliance into a standard RETMA 19" rack. The appliance has a 2U form factor.

Before unpacking the unit, ensure that the area is free from conditions that cause electrostatic discharge (ESD). Discharge static electricity from your body by touching a known grounded surface. Also, avoid touching pins, leads, or circuitry.

First Things First—Activate Your Warranty!

Before installing your new unit, it is essential that you activate your REO warranty. Technical and warranty support are not available until this is done. All you need to do is register your unit:

1. Go to the Overland Technical Support website at:

http://support.overlandstorage.com/

2. Using the MEMBER LOGIN E-mail and Password

fields, log in to the site.

Preparing REO 4500x for Installation

Overland recommends that you install the unit in a clean, air-conditioned environment where water and moisture cannot enter the case of the appliance. Keep the air as free from dust as possible.

Each REO 4500x comes with an Accessory Kit containing:

• Rail kit and hardware

• Power cords

• InfiniBand-to-MiniSAS cable

• MiniSAS-to-MiniSAS cable

• This quick start guide

CAUTION: Overland strongly recommends that you install power

conditioning and an adequately rated uninterruptible power supply (UPS), especially in areas prone to blackouts, power dips, and electrical storms.

Removing Drives from REO 4500x

1. Turn the carrier lever lock counterclockwise (Figure 1).

NOTE: If you are not yet a member, click the SIGN UP NOW button and follow the instructions to become a member. It’s free!

or Register a New Product and follow the on-screen instructions.

WARNING: The REO 4500x is shipped with the disk drives installed. Overland recommends that you remove the drive carrier assemblies from the REO to lessen the weight prior to rack installation.

CAUTION: Verify the AC power to the appliance is disconnected

before you install or remove the drive carrier assemblies.

The REO is intended to be grounded. Ensure it is connected to earth ground during normal use. Installing proper grounding helps to avoid damage from lightning and power surges.

3. Pull the lever and slide the drive carrier out (Figure 2).

NOTE: Do not remove the drives from their carriers. Doing so will void the drive warranty.

4. Number the carrier to ensure it is returned to the same

slot (Figure 3) after the unit is in the rack.

Installing REO 4500x in 19-Inch Rack

WARNING: Install multiple units in the rack from the bottom up. Extending a unit that has empty spaces beneath it might cause the rack to tip and cause injury or damage. Overland recommends that two people be used to insert or remove a unit.

Installing the Rail Kit

The REO 4500x comes with a rail kit for mounting the appliance in a 19-inch rack. These steps address the more common square-holed rack. Refer to the REO 4500 Setup Guide for installation in a rack with round holes.

1. Fully extend the rails, slide the red button on the inner

member forward, and remove the inner rail (Figure 4). Slide the intermediate member back in.

5. Attach right outer rail member to the rack as follows:

2. Identify and mark the screw holes on the front and rear

rails of the rack where the sliding rails will be installed.

NOTE: Be sure rear holes are horizontally in line with the front holes to assure the unit remains level.

3. Position the right inner rail against the appliance with

the locking tabs going through the holes on the rail, and slide the rail toward the rear to lock the tabs (Figure 5).

4. Repeat Step 3 to install the left inner member.

Installing the REO 4500x in the Rack

WARNING: It is recommended that a mechanical lifter (or at least two people) be used to prevent injury during rack removal and reinsertion.

1. At the front of the rack, pull out the middle members

until they lock (click) in the extended position.

2. Engage the inner members mounted on the appliance

with the intermediate members protruding from the rack, sliding the appliance in until it stops.

3. Push the white latch on both sides of the inner

members toward the rack and slide the inner members into the intermediate members, sliding the appliance all the way into the rack.

4. Slide the appliance in and out several times to ensure

that the rail members slide smoothly, the locks engage properly, and the appliance does not bind.

If binding occurs, verify that the front and rear flanges are mounted in the correct holes, readjusting the slide positioning as necessary.

5. Using the two screws provided, secure the appliance

flanges to the rack.

Reinstalling Drives in REO 4500x

Once the appliance is in the rack, reinstall the drives back into their original slots.

1. Position the drive carrier assembly with the release

button to the right before you slide it into the chassis.

2. Carefully insert the drive assembly with the lever lifted

until it completely enters the bay.

3. Push the lever back in place (Figure 8).

4. Turn the lock on the lever clockwise to secure the drive

carrier in the chassis.
