1.3 Warnings and Notices

1.3.3 Encryption (RTX Secure 222-3QR Only)

Please read the following before beginning installation.

1.3.1 General Care

• Proper grounding is strongly recommended to
prevent electrical damage to the unit or other
connected devices, including the computer host.
Avoid all dramatic movement, tapping on the unit,
and vibration.

• Avoid placing the unit close to magnetic devices,
high voltage devices, or near a heat source. This
includes any place where the product will be subject
to direct sunlight. Do NOT allow water to make
contact with the unit.

• Before starting any type of hardware installation,
please ensure that all power switches have
been turned off and all power cords have been
disconnected to prevent personal injury and damage
to the hardware.

• To avoid overheating, the unit should be operated in a
well-ventilated area.

• Though the Security Key port is mechanically identical
to the standard Mini-USB port, inserting Security Keys
into any other Mini-USB port may damage the keys
and render them useless. Please only use Security
Keys in RTX products.

• Likewise, inserting a Mini-USB cable or other device
into the unit’s Security Key port on the carrier may
cause internal damage and potentially lead to loss of

data.

• Any time power is cycled on the unit, the Security
Key should be installed prior to recycling the power in
order to access the data on the drive.

2 Introduction to RAID

A RAID (Redundant Array of Independent Disks) is an
array of multiple hard drives that are combined in a way
that provides faster performance and/or data safety. Your
RTX-3QR unit is capable of creating and managing several
different varieties of RAID. You may choose your preferred
RAID level based on factors such as disk capacity, desired
data safety, and desired performance.

• Remove the drives before transporting the unit to
prevent damage to the drive interfaces.

1.3.2 RAID

• Use only hard drives that are in perfect condition.
Avoid using drives that have ever developed bad
sectors during previous usage. This could lead to
possible device failure or loss of data.

• The unit supports SATA hard drives of various
specications and different capacities. However,
we recommend using drives of the same brand and
type for optimal performance. If drives of different
capacities are used in a RAID, the capacity of the
smallest drive will determine how much of each drive
is used. The additional capacity on the larger drives
will not be used by the RAID.

• RAID level 0 will allow you to use the full combined
capacity of the drives, and offers the best data
transfer speeds. However, RAID 0 offers no protection
for the data. If one drive fails in a RAID 0, the data on
all of the drives is irretrievably lost. Before creating a
RAID, investigate the various RAID types and choose
the one that is best for your needs.

2.1 Summary of RAID Levels

RTX-3QR supports RAID levels 0 and 1.

RAID
Level

0 Also known as striping. Data distrib-

uted across multiple drives in the ar­ray. There is no data protection.

1 Also known as mirroring. All data

replicated on two separate disks.
This is a high availability solution,
but due to the 100% duplication,
only half the total disk capacity is
available for data storage.

* The RAID level becomes available as a menu option when
exactly these numbers of hard drives are installed inside of
the RTX-3QR unit.

• Always back up data before switching RAID types.
Switching RAID types will destroy current data. You
must reformat your drives afterwards.

3 Installation Steps

3.1 TrayFree Bay Drive Installation

Note: This section refers only to RTX220-3QR.

a) Pull on the ejection handle to open the door.

b) Slide in your SATA hard drive, connector-end rst
with the label facing up.

c) Shut the door by pushing on the handle.

3.2 Drive Installation for RTX with Removable Carriers

This section refers only to RTX221-3QR and RTX Secure
222-3QR models.

a) Slide the drive carrier out of the RTX-3QR unit.

b) The carrier’s cover is held in place by a screw on
the rear of the unit. Remove the screw and then
remove the cover.

c) Slide the drive in from the front of the carrier.

d) Mate the connection on the drive with the
connection on the drive carrier circuit board.

e) Flip the drive/carrier assembly over and secure the
drive in place with the provided screws.

f) Attach the Temperature Control Cooling Sensor to
the top of the drive with a piece of tape.

g) Replace the carrier cover and secure the screw on
the rear of the carrier.

h) Slide the carrier into the RTX-3QR unit.

3.3 Host Connections

RTX-3QR units connect to your computer in one of four
ways; USB 3.0, USB 2.0, Firewire 800, or eSATA. Choose
one of the four cable types to use and plug it into the unit.
Each bay requires its own data connection.

See Section 7 for instructions on how to create a RAID and
Section 8 for instructions to format the drive with Mac or
Windows operating systems.

Your RTX-3QR unit is now ready to use! If the hard drive
is already formatted, it can be used right away. If the hard
drives are brand new, or their le systems are not compatible
with your operating system, the drive will need to be
formatted before being used.

If any of the drives are inaccessible after powering on the
unit, try the following steps:

1. Turn off the power.

2. Remove the drive(s) in question.

3. Reinsert the drive(s).

4. Turn on the power.

4 Operating Your RTX 3QR unit

Connect the data cables to the RTX-3QR unit and your
computer. Plug in the power cord to a grounded electrical
outlet. Insert hard drives into the unit and turn on the
power.

• For RTX220-3QR, the drives will begin to spin up
automatically

• For RTX221-3QR and RTX Secure 222-3QR, use the
included set of keys to turn the key lock 90 degrees
clockwise to power on each hard drive.

Note: When any hard drives are rst used with a RTX 3QR
unit they will show up as blank, unallocated drives and
you’ll need to create a RAID inside the unit before you can
use it. Note that creating a RAID will erase all data on the
drive, so be sure to back up your data before beginning this
operation.

7 RAID Conguration

You may skip this section if you purchased your RTX-3QR
unit pre-congured with drives. All two-bay RTX 3QR units
ship with RAID 1 as the default mode.

RTX-3QR offers two options for RAID conguration; RAID
0 and RAID 1. Stop all data transfers before setting or
changing RAID types or rebuilding a degraded array. Failure
to do so can result in the loss of data. To set up or change the
RAID type, disconnect all data cables and reboot the RTX
3QR unit. After the unit has initialized, the LCD will display
the drives’ mode and status.

9.1 Accessing RTX Enclosure’s Settings

Use FireWire 800 in either FireWire port or a USB type-A
to A cable in the USB 2.0/eSATA combo port to use CRU
Congurator to congure your product.

RAID Warning Buzzer
This buzzer will sound when the RTX enclosure is in
degraded RAID mode (a drive has failed and is in need of
rebuild or the RAID is rebuilding). This buzzer is disabled
by default. The RAID Status LED will glow amber if this
occurs, regardless of whether the buzzer is enabled or not.

9.2 Customizable Options

The following options are available on the Alerts tab of the
Congurator:

Conguration PIN
This feature allows you to set a PIN to prevent unauthorized
conguration. The default PIN is 0000. The RTX enclosure
only requires you to enter a PIN if a different value has been
set.

Buzzers
Place a check in the boxes to indicate which warning/alarm
buzzers you want to be activated or remove a check from the
boxes next to the buzzers you want to deactivate. When a
buzzer sounds, press Enter on the front of the RTX enclosure
to temporarily silence it until the RTX enclosure is next
rebooted.

System Warning Buzzer
This buzzer will sound when a drive reaches the temperature
set using the Drive temperature warning slider below. This
buzzer is disabled by default. As a visual alert, the System
Status LED will glow amber when the temperature is reached,
regardless of whether the buzzer is enabled or not.

RAID Alarm Buzzer
This buzzer will sound when the RAID has failed or is
invalid. The RAID Status LED will glow red if this occurs,
regardless of whether the buzzer is enabled or not.

Temperature Sliders
When your RTX-3QR reaches a certain temperature, buzzers
will sound if they are enabled (see the Buzzers subsection
above) and the fan will kick on. You may want to change
these default temperatures according to your environment.
With these sliders, you can change the default temperatures
of the:

• Enclosure fan kick-on

• Enclosure temperature warning

• Drive temperature warning

• Drive temperature alarm

10. RAID is Not a Backup

Because your RTX-3QR features redundant RAID modes
which protect against a hard drive mechanical failure, it is
an excellent part of any backup strategy. However, a RAID is
not, in itself, a backup strategy. Many things besides hard
drive failure can damage or erase your data:

• Corruption caused by unexpected disconnection during
data access (e.g. a cable is unplugged during a data
transfer, or the computer crashes or loses power while
writing to the drives)

• Corruption or destruction caused by viruses or other
malware

• Sabotage by a disgruntled employee or acquaintance

• Theft of your [Trademark] [enclosure/unit/etc.]

• Natural disasters such as re, ooding, etc.

System Alarm Buzzer
This buzzer will sound on 3 occasions:

• When a drive reaches the temperature set using the
Drive temperature alarm slider below

• When the enclosure reaches the temperature set using
the Enclosure temperature warning slider below

• When the fan fails

As a visual alert, the System Status LED on your RTX
enclosure will glow red when any of these three situations
occur, regardless of whether the buzzer is enabled or not.

Page 8

Considering these possibilities, any single copy of your
important data must always be considered at risk. That’s why
backing up is so important. Follow the 3-2-1 backup rule. Data
should exist in three different places on two different storage
media and at least one of those copies should be maintained
offsite.

Without an effective backup strategy, recovering data
may be impossible, or the cost of data recovery may be
quite expensive. The CRU warranty does not cover costs
associated with data loss (nor do the warranties of other data
storage manufacturers). Plan accordingly and backup data to
minimize downtime!
