6. USB 3.1 Gen 1 port — Attach the included USB 3.1 Gen 1 (Standard-A to Standard-B)

cable here.

NOTES:

• Although the ON/OFF switch controls power to the device, the Qx2 requires a data

signal in order to turn on. As long as the on/oﬀ switch is in the ‘on’ position, the Qx2 will

turn on when it receives a data signal through the interface cable (FireWire 800, USB 3.1

Gen 1, or eSATA). If there is no interface cable connected, or if the computer is oﬀ or in

a sleep or hibernation mode, the Qx2 will turn oﬀ.

• Only one interface (USB 3.1 Gen 1, eSATA, FireWire 800) at a time can be used.

• For the safe removal of your drive and to ensure that no data is lost, always eject or

unmount the drive from your operating system before powering oﬀ.

• In order for the computer to access volumes larger than 2TB, the operating system

needs to support large volumes (e.g., Windows Vista or OS X 10.4 and above).

1.5.2 RAID Selector Dial

To adjust your RAID settings, there is a dial on

the front panel of the Qx2, behind the locking

faceplate.

Use the silk-screened chart as a guide when

adjusting the dial to the desired RAID setting.

Proceed to section 2.3 for instructions on

changing the RAID levels on the Qx2.

MERCURY ELITE PRO Qx2 DEVICE SETUP

DEVICE SETUP

2.1 HARD DRIVE INSTALLATION

If you purchased the Mercury Elite Pro Qx2 with drives, they will be installed prior to

shipment. If you purchased drives for the Qx2 separately, follow the steps below to install

the drives into the Qx2, or to replace existing drives. Repeat steps 1 through 8 as necessary

for the number of drives you are installing.

1. Insert one of the included keys into the lock on the top left of the faceplate.

2. Turn the key clockwise, then pull the key towards you. The faceplate will swing open, as

shown.

3. Once the faceplate has swung open as far as it will go, pull up to remove it.

4. On the drive tray you wish to remove, turn the thumbscrew counter-clockwise until you

no longer feel resistance. Then hold onto the thumbscrew and pull the drive tray out.

5. Set the drive tray as shown on your work surface. If you are replacing an existing hard

drive, unscrew it from the drive tray at this time. If your Qx2 was purchased without drives,

each drive tray will have a plastic bar to help the drive tray keep its shape during shipping.

Unscrew the plastic bar and discard it before proceeding.

6. Place your hard drive inside the drive tray as shown. The label should face up and the SATA

connectors should be on the far rear corner of the drive.

7. Fasten the drive into the drive tray using six of the included screws.

8. Slide the drive tray back into the rails in the Qx2 and push until it is seated fully. Then, push

in on the thumbscrew and turn it clockwise until it stops moving.

NOTE: Be careful when sliding the drive tray back into the Qx2. If you encounter resistance,

do not force the drive tray. Remove it, check to make sure there are no obstructions and

that the drive tray is lined up correctly, and slide it in again.

MERCURY ELITE PRO Qx2 DEVICE SETUP

2.2 QUICK START

If you purchased the OWC Mercury Elite Pro Qx2 with drives, they have been pre-conﬁgured

as a RAID 5 array and the OWC Drive Guide formatting utility has been pre-installed to assist

you with the formatting process. Follow the steps below to use the Drive Guide to format

your Qx2 for Mac (OS X 10.4 and later) or Windows (XP and later).

1. Plug in your Qx2, then connect it to your computer using the proper cable. If you prefer to

use a diﬀerent formatting utility, do so at this time and skip to Section 2.3.

2. Your drive will show up as “OWC SETUP”. Open your drive to view its contents.

3. Double-click the OWC Drive Guide application.

4. Follow the simple on-screen instructions to complete the formatting process.

5. Once the formatting is ﬁnished the drive is ready to use.

NOTICE: If you purchased the Qx2 without drives and are adding your own pre-formatted

drives, be aware that the default mode is set to RAID 5. This means the Qx2 will erase any

pre-existing data or formatting on the drives that you install in the Qx2. This is true of all

modes except Independent Drive Mode. See Section 2.3.2 for more information.

2.3 RAID SETTINGS

2.3.1 Setting the RAID Mode

IMPORTANT NOTE: Drives of identical model and capacity are required for

all RAID types other than independent drive mode and span mode.

To switch RAID modes, follow these three steps (continued on next page):

1. With the Mercury Elite Pro Qx2 turned oﬀ, adjust the RAID dial so that the arrow is

pointing to the desired RAID level (see section 1.5.2, RAID Selector Dial).

2. While using a paperclip or small screwdriver to hold down the “Conﬁrm” button, turn

on the Qx2. The Qx2 will build the newly selected RAID, during which time the LEDs

will ﬂash. This process will take 20-30 seconds. When the LEDs stop ﬂashing, release

the “Conﬁrm” button. The Qx2 will show up on your computer as an unformatted

volume (or individual disks if you selected independent drive mode).

3. Format the new volume. Formatting instructions can be found at:

www.owcdigital.com/format

WARNING: Changing the RAID mode will create

a new array and destroy all data on the drives.

Changing the RAID mode will also require you to

reformat the array afterward.

MERCURY ELITE PRO Qx2 DEVICE SETUP

2.3.2 RAID Modes

IMPORTANT NOTE: Drives of identical model and capacity are required for

all RAID types other than independent drive mode and span mode.

Independent Drive Mode (One to Four Drives Installed)

Dial position: 4

Each drive will appear as a single volume. If you intend to use hard drives of diﬀering

capacity and model, this is the mode to use. To swap or replace drives, ﬁrst unmount

all drives and turn oﬀ the Mercury Elite Pro Qx2.

Span Mode (Two to Four Drives Installed)

Dial position: 2

The drives show up as one large single volume. The total size will depend on the

drives installed; you can use drives of diﬀerent capacities. A span is an array (not

RAID) in which the data is written sequentially across the drives. This combines the

capacities of the drives, but it does not provide any performance or redundancy

beneﬁts.

RAID 0 “Drive Striping”Mode (Two to Four Drives Installed)

Dial position: 0

The drives show up as one large volume with a size equal to the combined capacities

of all the drives used in the array. RAID 0 is used when speed is the primary objective;

it does not provide data redundancy. Data is distributed across two or more drives,

and is written and read without pausing to check parity information. This greatly

improves the speed, but if one drive fails, the whole array can become corrupted and

data will be lost. Always maintain a backup of your data!

RAID 1 “Drive Mirroring” Mode (Two Drives Installed)

Dial position: 1

The drives show up as one volume with a size equal to the capacity of one of the two

drives used in the array. RAID 1 copies (or“mirrors”) a set of data from the ﬁrst drive to

the second drive. This is useful when reliability and redundancy are more important

than capacity. When one drive fails, it can be replaced and the data will be rebuilt

automatically.

WARNING: Changing the RAID mode will destroy

the data on the drives. Be sure to back up your

data rst! See section 3.2 for information on

proper backup strategies.

MERCURY ELITE PRO Qx2 DEVICE SETUP

RAID 10 “Drive Mirroring with Striping” Mode (Four Drives Installed)

Dial position: 1

The drives show up as one volume with a size equal to the combined capacities of

half of the drives used in the array. RAID 10 creates an exact copy (or “mirror”) of a

set of data but also uses a RAID 0 “stripe” for speed. When one drive fails, it can be

replaced and the data will be rebuilt automatically.

RAID 5 “Drive Striping with Parity” Mode (Three or Four Drives Installed)

Dial position: 3

The drives show up as one volume with a size equal to the combined capacities of

all the drives in the array, minus one drive. RAID 5 uses block-level striping with parity

data distributed across all disks and therefore provides the perfect balance between

high performance and data integrity. When one drive fails, it can be replaced and the

data will be rebuilt automatically.

2.4 CHANGING DRIVES

2.4.1 Adding and Removing Drives in Independent Mode

When the Mercury Elite Pro Qx2 is set to independent mode, you can add or remove any

drive without needing to create a new RAID set.

IMPORTANT NOTE:To avoid data corruption it is essential to unmount all drives and

turn oﬀ the Qx2 before removing or adding a new drive. If you physically remove a drive

from the Qx2 without powering it oﬀ ﬁrst, any mounted drives will improperly unmount

from the computer.

2.4.2 Adding Drives to an Existing RAID Set

It is not possible to add more drives to an existing RAID set. In order to add drives, a new

RAID set must be created, which will destroy the data on the existing RAID set. If you wish

to add more drives, shut oﬀ the Qx2, then add the drives. Once all of the drives that you

wish to use are installed, go through the steps in section 2.3.1 to create the new RAID set.

2.4.3 Replacing Drives

When one of the drives fails, the corresponding LED will turn oﬀ. If only one drive has

failed and the RAID mode is set to RAID 1, RAID 10, or RAID 5, the data on the RAID

set will still be accessible, but it is strongly suggested that you replace the failed drive

immediately with another drive of identical model and capacity to ensure the continued

safety of your data.

MERCURY ELITE PRO Qx2 DEVICE SETUP

If more than one drive fails at the same time, or if one drive fails and the RAID mode is set

to RAID 0 or span, the data is lost (in span mode, only the data stored on the failed drive

is lost) and the volume cannot be accessed again until the failed drives are replaced and

a new RAID set is created.

When a drive fails, follow these steps:

1. Identify the failed drive and replace it (see section 2.1 for instructions). The LED that is

oﬀ indicates the failed drive. You do not need to turn oﬀ the Mercury Elite Pro Qx2 to

do this.

2. For RAID 1, RAID 10, and RAID 5, the RAID set will rebuild automatically. During the

rebuild process, the LED of the drive being rebuilt will ﬂash orange. Depending on the

capacity of the drives being used, the rebuild process will last from several hours to

a few days. Once the rebuild is complete, the drive LED will turn green and ﬂash with

activity as normal.

3. For RAID 0 and span, the drive LED will turn green, showing that the failed drive has

been replaced and the new drive is ready to be used. You will need to go through the

steps in section 2.3.1 to create a new RAID set before the Qx2 can be used again.

NOTE: We recommend that you do not turn oﬀ the power during the rebuild process,

but if power is interrupted, the data will continue rebuilding from where it left oﬀ as

soon as power is restored. If the Qx2 enters sleep or hibernation mode, this will also

suspend the rebuild process. We recommend that you use the operating system’s

power management controls to ensure that this does not happen.
